NHTSA ID Number: 10189670

Manufacturer Communication Number: 07-192-21

Summary

This bulletin announces availability of DMS reprogramming files to address DTCs B112C and / or B112E when they appear in memory.

SERVICE BULLETIN

NUMBER: 07-192-21
DATE: 03/15/21

INTRODUCTION:

This bulletin announces availability of DMS reprogramming files to address  DTCs B112C and / or B112E when they appear in memory.  In some cases,  when multiple functions are processed by the DMS control module at same  time, a task error may occur and cause the system’s indicator lamp to  illuminate yellow (as opposed to green during normal system operation).  A work flow to follow for proper diagnosis is also supplied in the Service  Procedure section below.

IMPORTANT NOTE:  This bulletin supersedes TSB 07-151-19R which outlined the steps to replace the DMS control unit instead of reprogramming it.

PRODUCTION CHANGE INFORMATION:

• This bulletin will be updated with the starting VIN information for this logic change when it becomes available.

PACK FILE APPLICABILITY:

IMPORTANT NOTES:

• These update files were included in the January, 2021 Select Monitor update .

• Each of the PAK Files in the table above consists of TWO (2) separate update files in FlashWrite. BOTH files listed in FlashWrite must be installed to complete the applicable update.

• A screenshot of the current FlashWrite screen is supplied below for reference.

SERVICE PROCEDURE / INFORMATION:

REMINDER:  Customer satisfaction and retention starts with performing quality repairs.

Step 1) Using the SSM4, check for any CURRENT DTCs.

Step 2) Diagnose any CURRENT DTCs (including B112C or B112E) using the procedure in the applicable Service Manual.

Step 3) Turn the ignition OFF then back ON again.

Step 4) Check for any STORED DTCs in memory.

CHECK: Is either DTC B112C or B112E stored in memory?

YES:  Proceed to Step 5 below.

NO:  If any DTC(s) other than B112C or B112E are stored, no further DMS repairs are necessary.

Step 5) Check the ROM ID numbers of the DMS C/M using the screen shots below as a guide:

Go to: Diagnosis > Each System > select Driver Monitor from the System List.

To check the ROM ID, select Software information to display the ROM ID.

CHECK: Is the ROM ID 50 0* 00 00 09, 50 0* 00 00 0C or 50 0* 00 00 0D?

YES: Proceed with reprogramming the DMS using the normal FlashWrite procedure.  Use the Pack File table above to select the proper reprogramming files from the FlashWrite result after entering the Vehicle Spec. parameters.

NO: Diagnose the DMS following the procedure in the applicable Service Manual.

Step 6:  Reprogram the DMS (if determined necessary).

Subaru of America, Inc. (SOA) highly recommends connecting either the Subaru Midtronics DCA8000 Dynamic Diagnostic Charging System or the Subaru Midtronics GR8-1100 Diagnostic Battery Charger to the vehicle and utilizing the Power Supply Mode feature anytime a vehicle control module is being reprogrammed.  Once the Midtronics charger is connected to the vehicle, if the battery is fully charged, it takes less than three (3) minutes to boot-up the charger, select the Power Supply Mode, and have the battery voltage stabilized and ready for reprogramming.

NOTES:

• For instructions on using the power supply mode, reference the applicable User Manual for the Midtronics DCA-8000 Dynamic Diagnostic Charging System and the Midtronics GR8-1100 Diagnostic Battery Charger on STIS.

• Confirm all electrical loads such as lights, audio, HVAC, seat heaters, and rear defroster are all switched OFF before setting up the charger for Power Supply Mode.

• Select the correct battery type (Flooded, EFB, Gel, AGM or AGM Spiral).

• Input the CCA which matches the vehicle’s battery. NOTE: OE and replacement batteries have different CCA ratings.  Always confirm the battery’s CCA rating before proceeding.

• If using a DCA-8000 Dynamic Diagnostic Charging System, set the power supply voltage to 13.5 volts.

• DO NOT connect the DST-i or SDI until the Power Supply mode function has completed its battery test mode and the Charging Voltage has dropped to and shows a steady 13.5 Volts on the display.

• Once Power Supply Mode reaches a steady 13.5 volts, connect the DST-i or SDI to the OBD connector and proceed with initiating the normal FlashWrite reprogramming process.

• Amperage will fluctuate based upon the vehicle’s demand for power. NOTE: If the voltage rises beyond 14V while programming is in process, the procedure will abort. This can indicate a need to test or charge the vehicle battery before any further attempt at programming is made.

VERY IMPORTANT:

This information is applicable to the Subaru Midtronics DCA-8000 Dynamic Diagnostic Charging System and the Subaru Midtronics GR8-1100 Diagnostic Battery Charger ONLY.  It does not apply to any other brand / type of “generic” battery charger whatsoever.  ONLY the DCA-8000 and the GR8-1100 and their Power Supply Mode feature have been tested and approved by SOA.

REMINDER:  If the DCA-8000 or GR8-1100 indicates the vehicle’s battery must be charged, charge the battery fully before proceeding to reprogram the vehicle while using the Power Supply Mode.

NOTES: 

• Control module failures resulting from battery discharge during reprogramming are not a matter for warranty. Should any DTCs reset after the reprogramming update is performed, diagnose per the procedure outlined in the applicable Service Manual.

IMPORTANT:  Before installation of the first reprogramming file can be accomplished, the DMS / CAN system must be “put to sleep” using the following procedure:

1. Switch the ignition OFF.

2. Close all windows, doors and rear gate.

3. Wait approximately 2 minutes.

4. When the red LED in the small DMS window located above the CP-1 multi-function touch screen display goes out, the DMS is “asleep”.

IMPORTANT:  For push-button start vehicles, the keyless access remote must be at least 7 feet away for the system to go to sleep.

IMPORTANT:  This DMS update requires installation of 2 reprogramming files as shown in the FlashWrite screenshot above.  Each file will take about 15 minutes to install.  BOTH update files MUST be installed.  If this update has been performed previously, a “Latest version already installed” message will be displayed.  Due to the system structure, the FlashWrite reprogramming procedure must be performed twice (once for each file) to complete the update successfully.

Step 7) After the FIRST file installation is successfully completed, switch the Ignition back ON and repeat the FlashWrite procedure to install the SECOND file.  The DMS / CAN system does NOT have to be put to sleep again.

Step 8) After successful installation of BOTH update files, switch the ignition back ON and using the SSM4, check again for any stored DTCs.

CHECK:  Does either DTC B112C or B112E remain stored in memory?

YES:  Diagnose the stored DTC(s) per the applicable Service Manual.

NO:  Proceed to Step 9 below.

Step 9) Repeat Step 5 above to confirm the new ROM ID number is 50 01 00 00 0E and complete the procedure.

Reprogramming

What J2534 reprogramming capabilities are available?

(4a) J2534 Reprogramming

Subaru reprogramming files using a generic (non-OEM) SAEJ2534 pass-thru vehicle programming device are available by contacting Service Technical Information Company toll free at 1-866-428-2278. The cost for the CD-ROM with all reprogramming files is $75.00 plus S/H and applicable state tax. Files will be updated four (4) times per year, in CD-ROM format, with all available reprogramming service information at the same above offered cost. Authorized Subaru Dealers are provided the same reprogramming information.

Before purchasing, the reprogramming details can be found in the following Reprogramming J-2534 Files chart. Click the link to view the PDF chart.

Subaru J2534 Reprogramming software meets the latest available J2534-1 specification. Our Reprogramming J2534 Files chart does not specify the Calibration Identification Number (CID); however, this information is included in our offered CD-Rom.

Note: The ECM or TCM being reprogrammed may already contain some or all of the reprogramming files listed in the Reprogramming J2534 Files chart shown by release date. It is possible to damage the vehicles ECM/TCMduring the reprogramming event. Once the reprogramming process has started, it is recommended not to interrupt the process until the event is completed. If you experience any problems, please contact your scan tool maker for further instructions.

(4b) Are all pre-2004MY Subaru vehicles compatible with J2534?

No. Subaru has no reprogramming capability for model years 1996-1998. Starting with our 1999 model year, please see our Reprogramming Pre-J2534 Files chart for affected model reprogramming information.

Both pre-J2534 reprogramming and J2534 pass thru reprogramming files are included in the offered HDS kit software for aftermarket service provider application.
