PURPOSE
In cases where a gas tank is filled with winter blend fuel, engine stalling may occur in cold weather
conditions, after the specific operations below:
1. Cold engine start
2. Turn key off
3. Engine restart
4. Shift to D (Drive) range
5. Tap acceleration pedal
This may be due to inappropriate fuel correction data after engine restart, where the Air/Fuel (A/F)
ratio becomes rich, resulting in the engine stalling.
This TSB instructs dealers to reprogram the Engine ECU with updated software to correct the issue.
AFFECTED VEHICLES
2018 - 2019 Eclipse Cross vehicles, produced before December 5, 2018
REQUIRED OPERATIONS

IMPORTANT: If an affected vehicle has a Malfunction Indicator Lamp (MIL) illuminated before
reprogramming, and DTCs are listed in the Engine ECU memory, diagnose and repair those DTCs per
the service manual before reprogramming. DO NOT reprogram the Engine ECU until the reason(s)
for other DTCs being set is corrected.

REPAIR PROCEDURE
SOFTWARE/MEDIC VERSION VERIFICATION
1.
Verify that the Engine 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 Engine ECU with the latest database (e.g., N190101 ) includes all past and
current reprogramming for TSBs of affected vehicles. It is not necessary to reprogram the Engine ECU
for each previous TSB.
For MEDIC 3.5/4 users only: (MUT-III STV users go to
step 5)
2.
Verify the MEDIC 3.5/4 is at version 3.5 and at
update 581 or higher.
If your MEDIC 3.5/4 update is at least 581, continue
with the Reprogramming Procedure.
