Passlock® Anti-Theft Learn Procedure

WARNING: This page does not describe the selected car, but rather 98 other vehicles, including the 2001 Saturn SW2, 2001 Saturn SL2, 2001 Saturn SL1, 2001 Saturn SL, and 2001 Saturn SC2. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: This procedure allows relearning of BCM module or VCM/PCM learned data code after replacement of BCM module, Passlock® sensor or VCM/PCM. DTC B3031 will set when entering programming mode.
  1. Turn ignition switch to OFF position. Replace failed component.
  2. Place transmission in Park (A/T) or Neutral (M/T). Turn ignition switch momentarily to START position (engine will not start), then leave in RUN position. SECURITY indicator will stay on for 10 minutes. After 10 minutes, when indicator light turns off, turn ignition switch to OFF position for 5 seconds.
  3. Repeat step  2 two more times. Auto learn procedure will be completed during next start attempt. If VCM/PCM was replaced, reprogram VCM/PCM. See appropriate SELF-DIAGNOSTICS article in ENGINE PERFORMANCE.
  4. Check for DTCs. If Passlock® codes exist, go to appropriate ANTI-THEFT SYSTEMS article in ACCESSORIES & EQUIPMENT. If PCM codes exist, diagnose affected DTC(s). See appropriate SELF-DIAGNOSTICS article in ENGINE PERFORMANCE.
