Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service

  • Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
  • Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
  • Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
  • Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.

Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.

1. What does OBDII code B1001 mean on a 2015 GMC Sierra?

The B1001 code indicates an SDM (Sensing and Diagnostic Module) Option Configuration Error, meaning the module’s configuration doesn’t match the vehicle’s specifications.

2. What are the common symptoms of code B1001 in a 2015 GMC Sierra?

Common symptoms include the airbag warning light staying on, a chime or warning message on the dashboard, and potential issues with airbag deployment functionality.

3. What causes the B1001 SDM Option Configuration Error?

This code is typically caused by an incorrect SDM configuration, a recently replaced or reprogrammed SDM, a mismatch in the VIN or system settings, or a communication error between modules.

4. How can I fix the B1001 code on my 2015 GMC Sierra?

The SDM may need to be reprogrammed or calibrated using a GM scan tool to ensure it matches the vehicle's configuration. This often requires a visit to a dealership or qualified technician.

5. Can I drive my 2015 GMC Sierra with the B1001 code active?

While the vehicle may still be drivable, the airbag system could be compromised, posing a safety risk in the event of an accident. It's important to address this issue promptly.

6. Does replacing the SDM automatically resolve the B1001 code?

No, replacing the SDM often requires reprogramming or configuration to ensure compatibility with the vehicle. Without this step, the code will remain active.

7. Can a dead or disconnected battery cause the B1001 code?

Yes, a loss of power to the SDM, such as during a battery replacement or disconnection, can sometimes trigger the code if the module loses its configuration.

8. How much does it cost to fix the B1001 code on a 2015 GMC Sierra?

Repair costs can vary but typically range from $150 to $300, depending on whether reprogramming or module replacement is necessary and whether work is done at a dealership.

9. Can I clear the B1001 code with a generic OBDII scanner?

No, clearing this code usually requires a GM-specific scan tool capable of reprogramming and configuring the SDM.

10. Will resetting the SDM clear the B1001 code permanently?

No, simply resetting the module won’t resolve the issue. The SDM must be reprogrammed or configured correctly to ensure the error does not return.
