This bulletin supersedes TSB-22-55-002 issued September 2022, to update the affected vehicles
and Warranty Op code Revisions are italicized and indicated by ◄.
PURPOSE
This Campaign Bulletin provides instructions to reprogram the HVAC ECU with updated
software.
BACKGROUND
Inappropriate software programming may cause an internal error in the AC AUTO AMP. The AC
system turns off unintentionally and does not automatically turn back on. The AC may be
turned back on manually within a few seconds; however, stored settings such as temperature,
are lost. Upon customer complaint, please reprogram the software.
AFFECTED VEHICLES
Certain 2022-23 Outlander:
ATTENTION:
•
Cooling fan may turn on during reprogramming.
•
The battery charger must be connected to the 12V battery while updating to prevent
battery discharge. A discharged battery may cause the reflash to fail, prevent the
update, and the HVAC ECU may require replacement.
VERIFY THE LATEST VERSION OF SOFTWARE is installed when the update is complete.
"Erase and Read all DTCs" must be performed since HVAC related DTCs may be generated
and stored.

ECU REPROGRAMMING CHART
SOFTWARE/MEDIC VERSION VERIFICATION PROCEDURE
1.
Verify that the ECU has not already been updated to the latest S/W number in the table above.
If the Engine ECU is at the latest level, reprogramming is not necessary.
NOTE: Reprogramming the ECU with the latest database (e.g., N220701 includes
all past and current reprogramming for TSBs of affected vehicles. It is not
necessary to reprogram the ECU for each previous TSB.
For MEDIC 3.5/4 users only: (MUT-III SEV users go to step 5)
2. Verify the MEDIC 3.5/4 is at version 3.5 and at update 754 or higher.
If your MEDIC 3.5/4 update is at least 754, continue with the Reprogramming Procedure.
If your MEDIC 3.5/4 update is below 754, update your MEDIC as follows:
