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's pins.
B0001:11 Driver Frontal Stage 1 Deployment Control: Circuit Short to Ground
B0001:12 Driver Frontal Stage 1 Deployment Control: Circuit Short to Battery
B0001:13 Driver Frontal Stage 1 Deployment Control: Circuit Open
B0001:1A Driver Frontal Stage 1 Deployment Control: Circuit Resistance Below Threshold
The cost to diagnose the B0001 Mercury code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
If the Restraints Control Module detects a short between the driver air bag stage 1 circuits and the circuits of another SRS component, it sets this Detected Trouble Code (DTC) and the DTC of the corresponding SRS component.
The Restraints Control Module (RCM) monitors all deployable device and sensor circuits for a signal cross coupled (short) between circuits. If the RCM detects a short between the circuits of one device and another device, it will store a DTC for each of the signal cross coupled faults in memory. The RCM sends a message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator. When a normal loop fault is present (one loop is either shorted to battery/ground, open circuit or low resistance), then signal cross coupled diagnostics will not be active. Once the normal loop fault is repaired, then the signal cross coupled diagnostics will resume.
