PASSWORD LEARN PROCEDURE
In order for a theft deterrent vehicle to run, a password is communicated between the Instrument Panel Cluster (IPC) and the PCM. If a PCM is
replaced, the new PCM needs to learn the correct password of the vehicle. When the new PCM is installed, the EEPROM calibration is flashed
into the new PCM and the vehicle will learn the new password upon initial ignition On. If the IPC is replaced, the PCM needs to learn the new
password from the IPC. The Password learn procedure is as follows:
1. Attempt to start vehicle, then leave the ignition On. The Theft System telltale will flash for 10 minutes.
2. When the Theft System telltale stops flashing, start the vehicle. Once the vehicle is running, the password is learned.
