  2. Learning the restraints ID--Refer to Body Control Module (BCM) Programming/RPO Configuration in Computer/Integrating Systems.
  3. Theft Learn--Refer to Programming Theft Deterrent System Components in Theft Deterrent. A new BCM will learn the Passlock™ information automatically but the PCM must still learn the theft information from the BCM.
  4. Program Key Fobs--Refer to Transmitter Programming in Keyless Entry.

BCM Reprogramming

If the body control module (BCM) is reprogrammed, the following procedures must be performed

  1. BCM Reprogramming--Refer to Body Control Module (BCM) Programming/RPO Configuration in Computer/Integrating Systems.
  2. Learning the restraints ID--Refer to Body Control Module (BCM) Programming/RPO Configuration in Computer/Integrating Systems.
  3. Theft Learn--Refer to Programming Theft Deterrent System Components in Theft Deterrent.
  4. Program Key Fobs--Refer to Transmitter Programming in Keyless Entry.

Inflatable Restraint Sensing and Diagnostic Module (SDM) Replacement

If the sensing and diagnostic module (SDM) is replaced, learning the restraints ID procedure needs to be performed. Refer to Body Control Module (BCM) Programming/RPO Configuration in Computer/Integrating Systems.
