PASSLOCK(tm) SYSTEM AUTO LEARN PROCEDURE

NOTE: This procedure allows relearning of BCM or VCM learned data code after replacement of BCM, Passlock(tm) sensor or VCM. DTC B3031 will set when entering programming mode.
  1. Using scan tool, clear all DTCs. See scan tool manufacturer's instructions. Turn ignition off. Replace component(s) as necessary.
  2. With transmission in Park (A/T) or Neutral (M/T), momentarily turn ignition switch to START position (DO NOT start engine). Leave ignition switch in RUN position (engine off). If VCM was replaced with new VCM, vehicle may start and procedure may not be needed. If replacement VCM was used even momentarily, SECURITY indicator light will flash for a few seconds, and then stay on for 10 minutes. After 10 minutes, when light turns off, turn ignition switch to OFF position for 5 seconds.
  3. Repeat step  2 twice more. Turn ignition switch to OFF position. Auto learn procedure will be completed during next start attempt. Clear all DTCs. If VCM was replaced, reprogram VCM. See appropriate SELF-DIAGNOSTICS article in ENGINE PERFORMANCE.
