Did you have the BCM programmed when you installed the new one?Also try this to relearn it, Attempt to the start vehicle. The vehicle will start and then stall.
Leave the ignition on until the Theft telltale turns off in approximately 10 minutes.
Turn the ignition off.
Restart the vehicle. The vehicle will start and on this attempt. The password is now learned.
Attempting to start the vehicle by bypassing the Passlock ll system or substituting parts without performing the password learn procedure may set a DTC P1631 and P1632.
If no password is received a DTC P1626, P1632 and U1064 may be set.
Post back with any other questions.
