Roll Rate Sensor: Testing and Inspection




Inflatable Restraint Sensing and Diagnostic Module Programming and Setup

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 setup the new SDM part number in the BCM. With a scan tool, select the SIR module setup. Select setup SDM Part Number in BCM and follow the on-screen instructions.
