Chevrolet Equinox Service Manual: Inflatable Restraint Sensing and Diagnostic Module Programming and Setup

The inflatable restraint sensing and diagnostic module (SDM)must be programmed with the proper calibration software. The modulestores and utilizes this information however if it is not properlyconfigured with the correct calibration software, the SDM will notcontrol all of the vehicle features properly.

Ensure that the following conditions exist in order toprepare for SDM programming:

The battery is fully charged.The MDI data link connectors are secure.The scan tool is loaded with the most current softwareversion.All disconnected modules and devices are reconnectedsecurely.This entire procedure has been reviewed beforeproceeding.

Do not reprogram the SDM unless directed by a serviceprocedure or a service bulletin.

Note:

The air bag indicator light may remain ON after the bodycontrol module (BCM), or SDM is replaced, and during theprogramming procedure for the BCM until after the procedure iscompleted. When installing a new SDM, there may be several DTCs setprior to programming. Once programmed, these DTCs should be inhistory and can be cleared.Failure to complete the following Setup procedure may causeDTC B1001 to be set in the SDM.

The following service procedures require either a programmingor a setup event performed for a complete repair:
