When the ignition is turned ON, the inflatable restraint sensing and diagnostic module (SDM) compares the restraints ID stored in the SDM to the restraints ID stored in the instrument panel cluster (IPC). The restraints ID being compared contains the last 4 digits of the SDM part number. For more detailed information concerning the Class 2 data lines, refer to Data Link Communications Description and Operation .
This diagnostic procedure supports the following DTC:
DTC B1001 Option Configuration Error
Ignition 1 voltage is within the normal operating voltage range.
• | The SDM disables all AIR BAG deployments. |
• | The SDM commands the AIR BAG indicator ON via class 2 serial data. |
• | The condition responsible for setting the DTC no longer exists. |
• | You issue a scan tool CLEAR DTCs command. |
• | A history DTC will clear once 255 malfunction-free ignition cycles have occurred. |
DTC B1001 is an indication that the restraints ID stored in both the IPC and SDM do not match. If either the IPC or engine control module (ECM)/powertrain control module (PCM) were replaced, the replacement modules needs to be reprogrammed for proper operation.
The numbers below refer to the step numbers on the diagnostic table.
This step checks to see if the correct VIN is programmed in the ECM/PCM.
This step explains the proper steps to perform after a ECM/PCM has been replaced in order for the ECM/PCM to operate properly.
This step explains the proper step to perform after a IPC has been replaced in order for the IPC to operate properly.

1 | Did you perform the Diagnostic System Check - Vehicle? | Go to Step 2 | |
Is the ECM/PCM programmed with the correct VIN? | Go to Step 4 | Go to Step 3 | |
With a scan tool and/or techline machine, program the correct VIN into the ECM/PCM. Refer to Control Module References for replacement, setup, and programming. Did you complete the programming procedure? | Go to Step 7 | -- | |
4 | Was the instrument panel cluster (IPC) replaced? | Go to Step 6 | Go to Step 5 |
5 | Replace the inflatable restraint sensing and diagnostic module (SDM). Refer to Control Module References for replacement, setup, and programming. Did you complete the replacement? | Go to Step 6 | -- |
With a scan tool, follow the instructions under the IPC SPECIAL FUNCTIONS menu to properly Synchronize the IPC with the SDM. Did you complete the synchronize procedure? | Go to Step 7 | -- | |
