INTRODUCTION

This bulletin announces the availability of new reprogramming files developed to address the following two symptoms:

SYMPTOM #1: 2022-23MY ONLY: After the EyeSight camera has been exposed to high humidity/temperature conditions without any operation, the cooling fans become inoperable, and DTC B28C7 is detected by the EyeSight Stereo Camera Assembly.

SYMPTOM #2: 2022-24MY ONLY: The EyeSight system enters into a temporary halt mode with an E5 halt code detected by the EyeSight Stereo Camera Assembly.

The new files contain optimized logic providing a more precise detection of DTC B28C7 and halt code E5. If any of the two symptoms listed above are reported by a customer. Follow the diagnosis and reprogramming procedures outlined in this bulletin.

SERVICE PROCEDURE/INFORMATION

SYMPTOM #1

2022-23MY ONLY: After the EyeSight camera has been exposed to high humidity/temperature conditions without any operation, the cooling fans become inoperable, and DTC B28C7 is detected by the EyeSight Stereo Camera Assembly.

STEP 1: Is DTC B28C7 detected?

YES: Proceed to Step 2.

NO: Continue diagnosis as per the applicable Service Manual.

STEP 2: Check the Fault Freeze Frame Data (FFD).

Is the Failure Detail Code (FDC) 00EC (FAN Speed is low) or 00EB (B28C7 detected during high temperature HALT)?

YES: Perform the reprogramming outlined in Step 3.

NO: Continue diagnosis as per the applicable Service Manual.

STEP 3: Review the prerequisites/battery charging information provided in the APPENDIX A section of this document. Install and turn on the power supply.

STEP 4: Using the Subaru Select Monitor (SSM), confirm the following EyeSight Stereo Camera Assembly information:

2022-23MY: The current control software version is 0421011E or 04210801.
2024MY: The current control software version is 0D210800 or 0D210801.
Confirm the Camera Temperature is less than 176°F (80°C).
Confirm the battery voltage is 13.5 Volts.

IMPORTANT: If the current software version is the latest version available, reprogramming is not required.

STEP 5: Reprogram the EyeSight Stereo Camera Assembly following the normal FlashWrite procedure and confirm the control software version has changed.

Was the reprogramming procedure successful?

YES: The procedure is completed. There is no need to recalibrate the EyeSight camera after the reprogramming procedure.

NO: Perform up to two more attempts. If the reprogramming procedure continues to be unsuccessful, replace the EyeSight Camera Stereo Assembly. Check the software status. If required, perform reprogramming after replacement.

SYMPTOM #2

2022-24MY ONLY: The EyeSight system enters into a temporary halt mode with an E5 halt code detected by the EyeSight Stereo Camera Assembly.

STEP 1: Does the Subaru Select Monitor data meet the criteria outlined below?

YES: Proceed to the next Step.

NO: Perform the HALT Code E5 diagnosis as per the applicable Service Manual. Refer to STIS: DIAGNOSTICS > EyeSight (DIAGNOSTICS) > EyeSight HALT Code > E5

NOTE: The pak file listings provided in this bulletin are the latest available at the time of publishing. Updates are often released thereafter without revision to the original bulletin. For this reason, it is critical to always have the latest version of Select Monitor software installed on your system. You can confirm if a later version is available by entering the CID listed in this bulletin into FlashWrite. If a newer CID is shown as available in FlashWrite, reprogram using that file.

IMPORTANT REMINDERS:

SOA strongly discourages the printing and/or local storage of service information as previously released information and electronic publications may be updated at any time.
Always check for any open recalls or campaigns anytime a vehicle is in for servicing.
Always refer to STIS for the latest service information before performing any repairs.

APPENDIX A

Subaru of America, Inc. (SOA) highly recommends utilizing either the Subaru Midtronics DCA8000 Dynamic Diagnostic Charging System or the Subaru Midtronics GR8-1100 Diagnostic Battery Charger to the vehicle in 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 will take 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.

PREREQUISTS:

Confirm there are no faults within the EyeSight® system. If there are any faults, they must be diagnosed, repaired, and cleared prior to reprogramming. Fully exit SSM prior to starting FlashWrite
Apply the Electronic Parking Brake (EPB). Switch the ignition switch to the "ON" position (engine off). Using the gear selector lever, set the vehicle in the Neutral (N) range. Wait at least 5 minutes after complete.
CRITICAL:
- If the gear selector is in the Park (P) range, it is possible for the ignition switch to turn off automatically while reprogramming after approximately 60 minutes. This will cause the reprogramming procedure to fail.
- DO NOT operate SSM during reprograming.
- DO NOT have the engine running during reprogramming.
Confirm the PC being use for reprogramming is connected to a known good power source. Turn off any screen saver settings. Make sure the PC is not in power saving mode and is set to the normal power mode.
Confirm all electrical loads are switched off such as climate control, seat heater, audio system, etc.
Connect a Midtronics DCA-800 or GR8-100 battery charger to the vehicle, utilize the Power Supply Mode feature to supply a stable 13.5 volts.

NOTE:

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 (Enhanced Flooded, Flooded, 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 DST-010 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 DST-010 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 14 Volts 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.
ALWAYS set the power supply voltage to 13.5 Volts when using Power Supply Mode. NEVER turn the ignition switch on when charging at voltages 15 Volts or higher.
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.

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.

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.
