B0001 LINCOLN Possible Causes
- Faulty driver airbag module
- Driver airbag harness is open or shorted
- Poor electrical connection in driver airbag circuit
- Faulty clockspring
- Faulty Restraints Control Module (RCM)
How to Fix B0001 LINCOLN Code?
Start by checking the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.
Technical Notes
What Does It Mean?
B0001: Driver Frontal Stage 1 Deployment Control 11: Short to Ground
B0001: Driver Frontal Stage 1 Deployment Control 12: Short to Battery
B0001: Driver Frontal Stage 1 Deployment Control 13: Circuit Open
B0001: Driver Frontal Stage 1 Deployment Control 1A: Circuit Resistance Below Threshold
When Is the Code Detected?
If the restraints control module detects a short circuit between the driver airbag stage 1 circuits and the circuits of another SRS component, it sets this detected problem code (DTC) and the corresponding SRS component DTC.
Possible Symptoms
Airbag warning light illuminated
B0001 LINCOLN Meaning
The Restraints Control Module (RCM) monitors all deployable device and sensor circuits for a coupled (shorted) signal between circuits. If the RCM detects a short circuit between the circuits of one device and another device, it will store a DTC for each of the signal cross-coupling faults in memory. The RCM sends a message to the instrument panel cluster (IPC) to illuminate the airbag warning indicator. When a normal loop fault is present (a loop is either shorted to battery/ground, open circuit, or low resistance), then the signal cross-coupling diagnostics will not be active. Once the normal loop fault is repaired, the signal cross-coupling diagnostic resumes.
