Important: The air bag indicator light may remain ON after the body control module (BCM), or sensing and diagnostic module (SDM) is replaced, and during the programming procedure for the BCM until after the procedure is completed, and the ignition key is cycled OFF and ON.

If the SDM is replaced you must perform the BCM reprogramming procedure in order for the BCM to relearn the new SDM ID. Refer to Body Control Module Programming and Setup . After, you must setup the new SDM. With a scan tool, select the SIR Module Setup. Select Setup SDM and follow the on-screen instructions.
