Passlock(TM) Theft Deterrent Relearn (Intrigue)

WARNING: This page does not describe the selected car, but rather 67 other vehicles, including the 2000 Saturn SW2, 2000 Saturn SL2, 2000 Saturn SL1, 2000 Saturn SL, and 2000 Saturn SC2. However, it is still accessible from the selected car via links, so may be relevant.

Password must be learned when Passlock(TM) sensor, BCM or PCM is replaced. This procedure must be performed after ignition switch replacement. If BCM is replaced, BCM must be programmed with proper RPO configurations before performing relearn procedures. If PCM is replaced, after programming, PCM will immediately learn the first password it receives. If password needs to be changed, learn procedure will need to be performed.

Turn ignition off. Turn ignition switch from OFF to START position, then leave in on position. SECURITY indicator will come on and stay on for at least 10 minutes. After SECURITY indicator goes out, turn ignition off for 5 seconds. Repeat this procedure 2 more times. After third time, turn ignition off. Turn ignition switch to START position, engine should start and run. Recheck BCM for Diagnostic Trouble Codes (DTC).

NOTE: 10 minute procedure requires special equipment to perform. If special equipment is not available, 30 minute procedure may be used. This procedure allows relearning of BCM or PCM learned data code after replacement of Passlock(TM) module, Passlock(TM) sensor or VCM. DTC B3031 will set when entering programming mode. Reprogram BCM with proper RPO configurations before performing 30 minute relearn procedure. After reprogramming a new PCM, PCM will learn incoming fuel continue password immediately. After initial password is learned, relearn procedure will have to be performed to change password.
