Introduction
The procedures below will program the body control module (BCM) correctly
after BCM related service, or setup the sensing and diagnostic module (SDM)
serial number in the BCM after the SDM has been replaced. Before you start, read these
procedures carefully and completely.

- Program the key fobs. Refer to
Transmitter Programming
in Keyless Entry.
- Clear all diagnostic trouble codes (DTCs) with the scan tool.
After the procedure is completed, the personalization settings of the BCM are
set to a default setting. Inform the customer that the personalization must be set
again. Refer to
