Installation

1. NOTE: If installing a new BCM , the ignition cannot be turned on until 2 keys are programmed to the vehicle. The BCM still communicates with the diagnostic scan tool with the ignition off. If necessary, use the previous diagnostic scan tool session or start a diagnostic scan tool session using the PCM part number or tear tag number located on the PCM .

   NOTE: If installing a new BCM , verify at least 2 of the vehicle keys are available prior to carrying out this procedure.

   To install, reverse the removal procedure.
   

NOTE: Carry out the remaining steps only if installing a new BCM .

1. NOTE: A diagnostic scan tool should not be used to program keys for this specific step.
