Test Description

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2004 Oldsmobile Bravada, 2004 GMC Envoy XUV, 2004 GMC Envoy XL, 2004 GMC Envoy, and 2004 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.

The numbers below refer to the step numbers on the diagnostic table.

  1. 2:  This step checks to see if the correct VIN is programmed in the PCM.
  2. 4:  This step checks to see if the BCM has been replaced.
  3. 5:  This step explains the proper steps to perform after a BCM has been replaced in order for the BCM to operate properly.
  4. 6:  This step checks to see if the correct VIN is programmed in the BCM.
  5. 7:  This step explains how to properly program the VIN into the BCM.
  6. 8:  This step checks to see if the SDM has been replaced.
  7. 10:  This step explains how to properly setup the SDM and BCM.

1 Did you perform the Diagnostic System Check - SIR? - Go to Step 2  Go to Diagnostic System Check - SIR 
  1. Install a scan tool.
  2. Turn ON the ignition, with the engine OFF.
  3. Use the scan tool to verify that the powertrain control module (PCM) is programmed with the correct VIN by comparing the vehicle identification number (VIN) that is stored in the PCM to the VIN plate of the vehicle.
Is the PCM programmed with the correct VIN?
- Go to Step 4  Go to Step 3 
3 Use the scan tool and/or the techline machine to program the correct VIN into the PCM.
Did you complete the programming procedure?
- Go to Step 11  -
Was the body control module (BCM) replaced? - Go to Step 5  Go to Step 6 
Program the BCM in order for the BCM to learn the restraints ID from the SDM. Refer to Body Control Module (BCM) Programming/RPO Configuration in Body Control System.
Did you complete the programming procedures?
- Go to Step 10  -
Use the scan tool to verify that the BCM is programmed with the correct VIN by comparing the VIN that is stored in the BCM to the VIN that is stored in the PCM.
Is the BCM programmed with the correct VIN?
- Go to Step 8  Go to Step 7 
Program the correct VIN into the BCM. Refer to Body Control Module (BCM) Programming/RPO Configuration in Body Control System.
Did you complete the reprogramming procedure?
- Go to Step 10  -
Was the sensing and diagnostic module (SDM) replaced? - Go to Step 10  Go to Step 9 
9 Replace the inflatable SDM. Refer to Inflatable Restraint Sensing and Diagnostic Module Replacement  .
Did you complete the replacement?
- Go to Step 10  -
10  Perform the Relearn Restraints ID Procedure. Refer to Body Control Module (BCM) Programming/RPO Configuration in Body Control System.
Did you complete the setup procedure?
- Go to Step 11  -

  1. Verify that all components, connectors, and CPAs are properly mounted.
  2. Use the scan tool in order to clear the DTCs.
  3. Turn the ignition switch OFF for 10 seconds.
Are all SIR components properly mounted and connected?
- Go to Diagnostic System Check - SIR  -
