INFLATABLE RESTRAINT SENSING AND DIAGNOSTIC MODULE PROGRAMMING AND SETUP
INTRODUCTION
The replacement of the inflatable restraint sensing and diagnostic module (SDM) will require that the SDM part number be relearned by other modules, such as the body control module (BCM), and the powertrain control module (PCM). The following procedures are designed to setup the SDM correctly and must be performed.
IMPORTANT:
- The Air Bag indicator may illuminate and DTC B1001 may set during the BCM reprogramming procedure.
- Use the 10-minute relearn procedure when programming the theft deterrent system.
1. Program the BCM with the proper regular production options (RPO). Refer to Body Control Module (BCM) Programming/RPO Configuration in Computer/Integrating Systems.
2. Clear any DTC.
3. Perform the Diagnostic System Check - Vehicle in Vehicle DTC Information.
