What is the B0001 error code?

The SRS control module continuously monitors deployment loop circuit integrity by measuring low-level diagnostic current across the driver airbag stage-1 deployment loop. The control module triggers this code upon detecting an electrical fault in the stage-1 deployment path. This occurs if it measures an open circuit, high resistance, a short to ground, a short to reference power, or an internal monitoring discrepancy against manufacturer limits.

What does B0001 mean?

The code means the Supplemental Restraint System (SRS) control module has detected that the monitored driver-airbag stage-1 deployment circuit is not behaving as expected. Depending on the vehicle and fault subtype, the issue may involve an open circuit, short circuit, excessive circuit resistance, connector/terminal fault, clockspring path, deployment device, or another monitored circuit condition. It does not prove that the driver airbag module itself is defective.
