DIAGNOSTIC STARTING POINT - SIR
Begin the system diagnosis with Diagnostic System Check - Vehicle . The Diagnostic System
Check - Vehicle will provide the following information:
The identification of the control modules which commands the system
The ability of the control modules to communicate through the serial data circuit
The identification of any stored diagnostic trouble codes (DTC) and their status
The use of Diagnostic System Check - Vehicle will identify the correct procedure for
diagnosing the system and where the procedure is located.
DTC B0012 OR B0013
Diagnostic Instructions
Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.
Review Strategy Based Diagnosis for an overview of the diagnostic approach.
Diagnostic Procedure Instructions provides an overview of each diagnostic category.

Diagnostic Fault Information
Circuit/System Description
If a malfunction is detected, a DTC will be stored in non-volatile memory. During a frontal crash
of sufficient force the inflatable restraint sensing and diagnostic module (SDM) will allow current
to flow through the deployment loop in order to deploy the steering wheel module. The SDM
performs continuous diagnostic tests on the deployment loops to check for proper circuit
continuity and for shorts to ground or voltage.
