The fix involves selectively erasing and reprogramming the PCM with new software. The wiTECH software level must be at release 13.02 or higher to perform this procedure.

Install a battery charger to ensure that battery voltage does not drop below 13.02 volts or rise above 13.5 volts during the flash.

The following must be performed once the PCM has been reflashed:

Turn the ignition key OFF for a minimum of 10 seconds to allow the module to update and power down.
Turn the ignition ON.
Using the wiTECH at the home screen, select PCM.
DTC P1302 – Trannsmission self learning will be present. Depress the clutch fully to allow DTC to store.
Perform the Cruise Control Learn Procedure. Press, then release the Cruise ON/OFF button on the steering wheel. Start the engine. Press the Cruise ON/OFF button to verify that the Cruise indicator illuminates on the cluster.
Perform the TLC relearn procedure.

a. Select PCM from Vehicle View.
b. Select the Misc. Functions Tab.
c. Set the parking brake and start the engine.
d. Select the “Clear Mis-fire TLC” function and verify that the Misfire TLC has been cleared.
e. Select the “Monitors drop down list and select “OBDII Monitors”.
f. Select the “Mis-fire Mon SWC” screen.
g. While watching the Mis-fire Mon SWC screen, allow the engine to warm up until the coolant temp has reached 140 degrees F.
h. Once coolant temp has reached 140 degrees, perform a 6,000 rpm wide open throttle stab and let rpm return to idle.
i. Verify that the Mis-fire monitor status on the Mis-fire Mon SWC screen has changed from “Waiting” to “In Progress”. If 6000 RPM was not achieved, perform Step H again.

Clear any DTCs that may have set in other modules. Type the necessary information on an Authorized Modifications Label and attach it near the VECI label.
