SERVICE PROCEDURE / INFORMATION:
IMPORTANT: Confirm the following prior to proceeding with any reprogramming.
•
Confirm Subaru Select Monitor (SSM) has communication with the DCM and no DTCs are
present in the Telematics system.
•
Review the information supplied in the Appendix A section of this bulletin prior to proceeding
with any reprogramming.
•
Record the subscription status information prior to proceeding with any reprogramming. This
information is required when reprogramming is completed.
SOFTWARE VERSION VERIFICATION:
Using the SSM, verify and record the current DCM software status. Using the work support function,
read the “Software Information” data monitor.
Is the current software version DCM_06.00.17_20190816?
YES- The DCM has the latest version. Reprogramming is not required.
NO- Confirm the next course of action and applicable software file by referring to the
table below.
Current DCM Software Version
Next Step
Applicable Software File
DCM_05.00.10 or 05.00.17
Proceed to Step 1 of Phase 1.
86229DCM01-1.pak

Proceed to Step 1 of Phase 2.
86229DCM01-2.pk2
DCM_06.03.17_20191029
(Rare Cases)
Phase 1 and 2 reprogramming is
complete. Proceed to Step 1 of Phase 3.
86229DCM02.pk2
Follow the specific instructions for Phase 1 -3 reprogramming based on the starting DCM software
version. Each phase involves selecting the appropriate file and initiating the reprogramming process
through the SSM tool.
CAUTION: Installing the incorrect file will damage the DCM and void all Warranty. ALWAYS
confirm the software version and follow the correct course of action.

PHASE 1: REPROGRAMMING INTERMEDIATE 86229DCM01-1.PAK (IF THE CURRENT
SOFTWARE VERSION IS 05.00.10 OR 05.00.17):
IMPORTANT: Due to the duration of each reprogramming procedure and consecutive
reprogramming file transfers required to complete this 3G Sunset reprogramming update, a Subaruapproved Denso SSM cable is STRONGLY recommended. Cables from other manufacturers may not
meet data transfer rate and interference shielding requirements to ensure error-free data transmission
during reprogramming.
CAUTION: Ensure the Midtronics GR8 / Midtronics DCA-8000 set to Power Supply Mode is
connected to the vehicle, the parking brake is engaged, ignition is in the “ON” position, the engine
is OFF, the shift selector in NEUTRAL and the wheels are blocked. This must be done to ensure the
power supplied to the DCM is not turned off. If this step is not performed, the CAN will power down
the DCM during the reflash, and the reprogramming will fail, resulting in irreparable damage.
FOR KEY START VEHICLES:
•
Turn the ignition key ON (engine OFF).
•
Depress the brake pedal and move the Shift Lever into NEUTRAL.
•
Leave the ignition ON.
FOR VEHICLES EQUIPPED WITH KEYLESS ACCESS AND PUSH-BUTTON START:
•
Without touching the brake pedal, press the Push Button Ignition Switch twice to put the
ignition system is in IG ON mode (Engine OFF).
•
Depress the brake pedal and move the Shift Lever into NEUTRAL.
•
Leave the ignition ON.
CRITICAL: DO NOT leave the vehicle in park! Doing so will damage the DCM requiring
replacement.
