Password Learn Procedure For Passlock® Anti-Theft System

NOTE: If BCM or VCM are replaced, modules must be programmed with vehicle configuration before performing Passlock® reprogramming.

Password learn procedure must be performed if VCM, Passlock® module or sensor is replaced. A password is communicated between VCM and Passlock® module to provide engine operation. If VCM is replaced, VCM must learn password from Passlock® module.
Momentarily turn ignition switch to CRANK position, but do not start engine. Release switch to RUN position, but do not turn off. Wait 10 minutes and observe SECURITY indicator light.
NOTE: Ensure battery is fully charged before proceeding. Ensure steps are followed in correct order or procedure may need to be repeated.
If Passlock® sensor was replaced, SECURITY indicator will flash for 10 minutes. If Passlock® module was replaced, SECURITY indicator will flash for a few seconds, then remain on for 10 minutes. If VCM was replaced with a new programmed VCM and connected to vehicle for the first time, vehicle will start and this procedure is not necessary. If replacement VCM was connected to any other vehicle at any other time, SECURITY indicator will flash for a few seconds, then remain on for 10 minutes.
After 10 minutes, SECURITY indicator light will turn off. Turn ignition switch to OFF position and wait 10 seconds.
Repeat programming procedure 2 more times. New security code is ready to be communicated. New password is learned on next ignition switch lock cylinder from OFF to CRANK to ON.
