BCM Replacement

IMPORTANT: If the BCM is replaced, refer to BCM Programming/RPO Configuration to program the new BCM to the current ignition key. Remember the BCM can only be programmed once. Programming and Relearning

Do not replace the BCM unless directed to do so by the diagnostic procedures in this section. Most system faults are traceable to faulty wiring, connectors or system components other than the control module. Do not replace the BCM before performing a complete diagnosis. This may result in the replacement of a good BCM and a recurrence of the fault.
