CDA FAQ

GENERAL INFORMATION Why did the Chrysler Diagnostic Application (CDA) replace the EDT2? The CDA is replacing the EDT2 due to a VP-level decision (Dan Knott – VP of Global Service, Bill Mattingly – VP of Core Core EE Engineering, and Bob Lee – VP of Powertrain Engineering) to establish a “single” comprehensive diagnostic and flash tool application for Chrysler Engineering, Manufacturing, and Service. This was done in order to improve overall EE product quality, improve service quality and readiness, reduce tool redundancies, and consolidate resources.

Why do I need to for access to the Diagnostic Workbench? The Diagnostic Workbench consists of proprietary information owned by DaimlerChrysler. Registration permits access to that information. The Diagnostic Workbench consists of 2 separate instances: • The Chrysler Diagnostic Workbench, http://workbench.ctc.chrysler.com for internal Chrysler employees • The Supplier Diagnostic Workbench, https://www.diag.dcctools.com , for external s and suppliers. o Suppliers may initially sign up for access to the workbench web site at https://diag.dcctools.com/ Having separate Diagnostic Workbench websites was done to protect sensitive data and applications.

What is currently ed by the Chrysler Diagnostic Application? The Chrysler Diagnostic Application (CDA) s the following hardware platforms:

• • • •

Vector Hardware (CANcardX, CANcardXL, CANcaseXL, CANcardXLe, CANboardXL) StarMOBILE (service tool) wiTECH VCI Pod (service tool) StarSCAN (up to version E4.02 only) o E5.01 and forward is NOT ed on StarSCAN

The CDA has the following functionality:

• • • • • •

UDS and KWP2000 based ECU communication Functional CAN Messaging ECU DTCs ECU Flash CAN Bus Logging Engineering Features o Read/Write Control o I/O Control o Fault Management

What are ENG files? ENG files are essentially containers for ECU specific data and functionality. ENG files are released according to variant, version, and minor version. The contents of an ENG file are: • • • •

ECU Diagnostic Database ECU Text (Strings) File Security Unlocks Off Board Routines

When any of the above contents needs to be added or updated, a new minor version of the ENG file must be generated and then posted to the Diagnostic Workbench. All diagnostic data is maintained and released by the Core Vehicle Diagnostics group at Chrysler. No diagnostic data (ENG files) are bundled with the CDA software. The of the CDA must import them. ENG files cannot be bundled with the CDA software because new ones are released daily. See the CDA Guide for instructions on how to import ENG files into the CDA.

Does the Chrysler Diagnostic Application Vector hardware (e.g. CANcardX/XL)? Yes, for Vector hardware such as CANcardX, CANcardXL, CANcaseXL, CANcardXLe, and CANboardXL is present in the latest CDA version.

How can I order a StarMOBILE or wiTECH VCI Pod for use with the Chrysler Diagnostic Application? StarMOBILE and wiTECH devices may be purchased directly from the supplier, Bright Star Engineering. To place an order, please Roy Nachowicz at [email protected] or 617-224-4912.

CDA FAQ

Where can I get additional assistance with the Chrysler Diagnostic Application (CDA) or Diagnostic Workbench? The first place you should look for assistance is on the Diagnostic Workbench under . If you have a bug or new feature request, you can click on the Submit Issue menu item. All documentation can be found under the Library menu. If you cannot find the answers you are looking for in the Documentation or Training Aids found there, please call the Engineering Hotline at (810) 287-3806 or e-mail [email protected].

TOOL FEATURES I have installed the latest version of the application. Why don’t I see any ECU or vehicle data? The Chrysler Diagnostic Application is deployed without any ECU or vehicle data. ECU and other data required by certain features of the application are available via the Diagnostic Workbench (specifically eRepository). The following types of data packages must be obtained from the Diagnostic Workbench: Chrysler Diagnostic Workbench

• • •

ECU diagnostic data files (.eng files : My Workbench > ECU View > select either ECU View or Vehicle View to obtain appropriate .eng files) Gateway Configuration Files (GatewayConfig.bndl: Tools > Software & Drivers) ECU Flash Files (.efd files: My Workbench > ECU View > Flash)

Supplier Diagnostic Workbench • ECU diagnostic data files (.eng files: External s must their Chrysler Core Release Engineer to obtain the necessary .eng files or ECU Diagnostic Packages that they require. • Gateway Configuration Files (GatewayConfig.bndl: eRepository > Gateway Configuration • ECU Flash Files (.efd files: eRepository > Flash Files) These pieces of data must be transferred to the tool by the using the File Management features of the application.

How does the CDA handle Off Board Routines? An off board routine is a custom script that streamlines a series of functions that need to be performed on an ECU or set of ECUs. CDA version E4.01 and forward will Off-Board Routines. Off Board Routines are deployed inside of ENG files. When a routine is ready for release, new min versions of an ENG files are created. Which ENG files are created depends on what variants and sometimes versions of an ECU the routine is intended to be used on. The new routine is then put inside those ENG files and posted to the Diagnostic Workbench website where they can then be ed and imported into the CDA.

CDA FAQ

If a new off board routine is needed for engineering use, a request should be entered through the Jira issue tracking system which can be accessed through the Diagnostic Workbench under -> Submit Issue. There is a project dedicated to off board routine requests listed on that page. The request will be reviewed by the CDA Release Planning team and eventually scheduled for implementation.

How can I change the CAN baud rate? All hardware configuration on the CDA can be done immediately when the application launches. The physical communication channels of your Vector hardware or StarMOBILE/wiTECH tools can be mapped to a bus type, and thus a specific baud rate for that bus. Please click on the Help button in the upper-right corner for assistance with the device configuration.

How does the StarMOBILE’s vehicle connection system work? There are certain conditions that must exist for the StarMOBILE tools to communicate with a vehicle. The first conditions that must be met for the tool to operate properly are that power and grounds must be connected at the Data Link Connector (DLC). This means that pin 16 on the DLC will need to have battery voltage (B+) at all times and that pins 4 and 5 have a “clean” path to ground. When the StarMOBILE is turned on and plugged into the DLC, the light near the power button on the tool will turn green when vehicle power is present. If the tool is running off of its internal battery, then the light will be a solid red. A green light with an occasional red blink means that the tool is running off of the vehicle’s battery and charging its internal battery. Note: on boot up, the tool may take a few seconds to recognize that vehicle battery is present. If you don’t see a green light, then check all of your cable connections from the StarMOBILE tool to the DLC. Also check that the vehicle’s battery voltage is at least 10.5 Volts. This is the approximate voltage at which the tool will switch from vehicle power to internal battery power for most of its hardware. Vehicle communications hardware on the StarMOBILE tool would still draw off of vehicle power and function above 6 Volts. If all of these conditions are met and you are still having trouble communicating, then try a different vehicle cable or plug into a different vehicle. If vehicle battery is present, the StarMOBILE tool will attempt to identify the cable attached to it. There are different types of cables that can be connected to the tool vehicle connector, so be sure you’re using the correct type.

How can I easily connect the wiTECH VCI Pod or StarMOBILE to ECUs that are not on a vehicle or buck? When connecting to ECUs in a desktop setting, the Chrysler Diagnostic Application development team recommends the use of a breakout box. A breakout box provides easy access to all of the lines in the Vehicle On-Board Diagnostic connector. Using standard banana plug connectors, you can easily connect the CAN, power, and ground lines to the appropriate J1962 pins so that the standard vehicle cables can be used. Breakout Boxes are available from Dearborn Group and may be purchased by ing their sales department at (248) 488-2080 or [email protected]. The part number is DG-OBDII-BOX.

*Note: When using a desktop setup, ensure that the ground lines, on J1962 pins 4 and 5, are tied together for a common ground. The table above shows that the vehicle’s diagnostic connector has the Diagnostic CAN-C bus available on pins 6 (CAN+) and 14 (CAN-). Since the StarMOBILE device was initially designed for vehicle connection in the service environment, the only CAN-C bus available on these devices on pins 6 and 14 of the vehicle cable. There is no multiplex capability on the StarMOBILE. Therefore, if you are attempting to connect to the CAN-C (pins 1 and 13) bus on a development vehicle, you must route the pins accordingly. A breakout box (described above) provides an easy way to do this. The wiTECH VCI Pod has two high speed CAN-C transceivers wired to pins 6/14 and 3/11. The CDA s dual channel communications over these pins simultaneously. So, the new Powernet vehicle architecture is ed out of the box. Please also note that the wiTECH VCI Pod and StarMOBILE devices do not supply any additional termination to the CAN lines. Therefore, depending on the ECU, you may have to manually add termination to the bus.

CDA FAQ

VECTOR HARDWARE TROUBLESHOOTING How do I get my CANcardX working with CDA? If you are using CANcardX (not CANcardXL), then you must ensure that your CANcardX driver is at version 5.2 or later. You can check the driver version by going to your PC's Control and selecting either CAN Hardware or Vector Hardware. If the version is less than 5.2, then go to the Software Updates page on the Diagnostic Workbench and the CANcardX driver update in the list. You'll then need to extract those driver files and follow the normal procedure to update hardware drivers (you may need access to your PC to do this).

I am having communication problems with the CDA using Vector CANcardX and a 1041Aopto transceiver cable. What could be the problem? Vector has indicated that the 1041Aopto transceiver cable does not the CANcardX because the 1041Aopto cable was released after for the CANcardX halted. The 1041Aopto cable must be used with a CANcardXL.

The CDA won’t work on my PC. It says “ECU is not responsive” for all ECUs. What could be wrong? There are multiple situations where this can occur: 1. If you are a CANcardX , the first thing to check is your Vector CANcardX driver version. The driver version can be found in the Vector Hardware Config screen by going to your PC’s Control , then choosing either “CAN Hardware” or “Vector Hardware”. Click on “CANcardX” and the driver version should appear in the right pane of the screen.

The driver version needs to be at 5.2.62 or above in order for the CDA to function properly. If your driver needs to be updated, then you’ll need to the latest

If you are not familiar with how to update hardware on your PC, the Engineering help line or IT personnel. 2. Make sure your transceiver cable (CANcab) is attached to CANcardX/XL and detected by the Vector Hardware Config software prior to starting the CDA. You can check whether the cable is detected by going to the Vector Hardware Config screen (click Control , then click either “CAN Hardware” or “Vector Hardware”) and clicking on your CANcardX/XL. The screenshot below shows what the screen will look like when the cable is detected.

3. Sometimes if logging is started with CANalyzer or CANoe on Channel X, and then the CDA is started and also connected to Channel X, the CDA may be blocked from using that channel. It is recommended that logging in CANalyzer or CANoe should not be started until after the CDA is launched.

SOFTWARE UPDATES Where do I get updated versions of the Chrysler Diagnostic Application? Updated versions of the application can be found in the Chrysler Diagnostic Workbench under Tools > CDA > Software & Drivers section and on the Supplier Diagnostic Workbench in the Software Updates section. There are separate files for the PC and StarSCAN versions of the application.

CDA FAQ

How do I find instructions on how to update my wiTECH VCI Pod or StarMOBILE software? See the CDA Guide. On the Chrysler Diagnostic Workbench this can be found under select > Library > Library Filters>Applications> CDA Guide. On the Supplier Diagnostic Workbench on the Home Page under the Latest News Section.

SUPPLIER DIAGNOSTIC WORKBENCH The supplier version of the Diagnostic Workbench contains the CDA Software, the Gateway Configuration file, and flash files created by external s. ECU Diagnostic Packages which include the .eng file, the Diagnostic Data Table and the change log, are only available on the Chrysler Diagnostic Workbench. External Diagnostic Workbench s must their Chrylser Core Release Engineer to obtain those eng files or ECU packages that they require.

CHRYSLER DIAGNOSTIC WORKBENCH The ECU Diagnostic Package I am looking for is not available on the Diagnostic Workbench under My Workbench> ECU View. What is the process for having it released to the site? The ECU Release Engineer should the appropriate Core EE Vehicle Diagnostics (Art Merriweather’s team) team member to request that the ENG file for the ECU be released to the Chrysler Diagnostic Workbench (specifically My Workbench > ECU View / Vehicle View).

When do I need to use the ENG files found in on My Workbench under ECU View or Vehicle View? The ENG files are similar to the KWP01 files that were used with EDT2. The ENG files are required when attempting to communicate with and perform diagnostic functions on an ECU. The packages contain all data for the given variant of the ECU. You can search for .eng files by creating a filter under ECU View or for a specific Vehicle MY combination. Once you have the filters Diagnostic Data Results and have selected the specific files you need, you can then choose to the entire ECU Diagnostic Package of just the .eng file by selecting the appropriate radio button before ing.

When do I need the Gateway Configuration Package found in Tools > Software & Drivers? The Gateway Configuration Package is required in order to provide the Chrysler Diagnostic Application the ability to filter the list of ECUs shown to the . Because the Central Gateway ECU contains LIDs/PIDs describing which ECUs are built on a given vehicle, the CDA can use this information to display only those ECUs. This is known as a CGW Filter. The Gateway Configuration file is only necessary when using the CGW Filter, Vehicle Wide DTCs, and the Vehicle Scan features of the CDA.

JIRA What is Jira? Jira is an online system used to track issues, bugs, and new feature requests that emerge during a project. It provides a quick and effective way of notifying the development team of issues in order to get them resolved quickly. The Chrysler Diagnostic Application development team is using Jira as a portal for s to notify them of any issues or feature requests they encounter. For efficient resolution of issues, all correspondence regarding a specific Jira issues should be within the Jira project. The Jira project will notify the development team and the issue reporter via an automatic email when an update is entered In addition, Jira should also be used by ECU Release Engineers to request flash for new ECUs.

How can I get for the Jira application? Atlassian, the company that developed Jira, has an extensive online system. Please see their website, http://www.atlassian.com//jira/ for help with the Jira application.

Implementation Requests (CVD and GSD only), and Noncompliant ECU Issues should be created here as well. EFD Builder (EFD): Any bug, new feature, or task related to the EFD Builder. Off Board Routines: Requests for for specific Off Board routines are created here.

What are the differences between the PND and EFD file formats? The EFD (Extensible Flash Definition) file format was created to be a self-contained flash file which addressed many of the shortcomings of the PND file format. With PND, any special handling required in an ECU’s flash process, such as security unlocks, would require changes to the application code. EFD was designed to handle this through metadata in the file so that a generic flash application can be used and is not required to check for special requirements of the ECU during the flash process. The PND file format was originally created for J1850 flash, and later modified to KWP2000 over CAN flash. Due to the modifications to the file format that would be required to protocols such as UDS, the EFD file format was developed to be extendable and handle KWP2000, UDS, and future protocols. Other requirements of the flash process that are not provided for with PND but have been taken into with EFD are non-sequential addresses in logical blocks, an ECU containing more than eight logical blocks, and multiple address handling.

Why don’t I see an ECU in the list of available ECUs in EFD Builder? You will not be able to build an EFD for an ECU until the CDA development team has received the metadata mentioned in the question above. Because this metadata is stored within the EFD file, it must be entered into the system before an EFD can be built. The ECU Release Engineer is responsible for requesting flash for their ECU by creating a request in Jira. For more details on how to request flash , see the ‘CDA New ECU Flash Process’ document located on the Chrysler Diagnostic Workbench site under Tools>Documentation & Training Aids section and on the Supplier Diagnostic Workbench site on the Home Page under Latest News.

Can EFD Builder and the CDA’s flash software multiple address ranges or 'holes' in the memory map for each logical block? Yes, EFD Builder and the CDA’s flash software will multiple address ranges for each logical block. When defining an ECU, EFD Builder s multiple address range entries. For example, an ECU may have a memory map of 0000-7FFF and C000-FFFF for logical block 1 and 8000-BFFF for logical block 2. When importing a s-record file having code for both logical blocks inside, EFD Builder will correctly parse the physical blocks into their correct logical blocks.

Can EFD Builder and the CDA’s flash software overlapping logical blocks where the address ranges are the same for two logical blocks? Yes, as long as the code for each of the logical blocks are in separate s-record files. When importing an s-record file, if a particular physical block can belong to more than one logical block, EFD builder will ask which logical block the physical block belongs. 1/12/09

CDA FAQ

How many logical blocks can EFD Builder and the CDA’s flash software ? EFD Builder and the CDA’s flash software can up to the theoretical maximum that the protocol allows. For the KWP2000 protocol, the maximum is 254 code logical blocks, 254 data logical blocks, and 254 boot logical blocks. For the UDS protocol, the maximum is 255 logical blocks.
