PURPOSE
Due to the supplier improperly programming of the Electronic Power Steering ECU (EPS-ECU), when
replacing the EPS-ECU, the coding process cannot be competed. When attempting to code the
replacement service part, caution “Busy (21)” will be displayed as well as DTC U1195 will be stored.
NOTE: If failure to code the replacement service part occurs, Do NOT attempt to code the part multiple
times.
This TSB instructs dealers to reprogram the EPS-ECU with updated software to correct the coding
issue.
AFFECTED VEHICLES
2018 - 2019 Eclipse Cross vehicles
REQUIRED OPERATIONS
1.
2.
Confirm your MUT-III is updated with the latest reprogramming database.
Reprogram the EPS-ECU with the new software. Refer to the “EPS-ECU Reprogramming Chart”
for new software information.
IMPORTANT: If an affected vehicle has a Malfunction Indicator Lamp (MIL) illuminated before
reprogramming, and DTCs are listed in the EPS-ECU memory, diagnose and repair those DTCs per
the service manual before reprogramming. DO NOT reprogram the EPS-ECU until the reason(s) for
other DTCs being set is corrected.

REPAIR PROCEDURE
SOFTWARE/MEDIC VERSION VERIFICATION
1.
Verify the identification mark on the EPS-ECU is D0 (before countermeasure).
If the Identification mark is D6, then the EPS-ECU has the countermeasure software and
reprogramming is not necessary.
2.
Verify that the EPS-ECU has not already been updated to the latest S/W number in the table
above.
If the EPS-ECU is at the latest level, reprogramming is not necessary.
NOTE: Reprogramming the EPS-ECU with the latest database (e.g., N190302) includes all past and
current reprogramming for TSBs of affected vehicles. It is not necessary to reprogram the EPS-ECU for
each previous TSB.
For MEDIC 3.5/4 users only: (MUT-III STV users go to
step 5)
3.
Verify the MEDIC 3.5/4 is at version 3.5 and at
update 595 or higher.
If your MEDIC 3.5/4 update is at least 595, continue
with the Reprogramming Procedure.
Version and Update
numbers
If your MEDIC 3.5/4 update is below 595, update
your MEDIC as follows.
