Normal Operation

WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

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.

DTC DESCRIPTION TABLE

DTC Description Fault Trigger Condition
  • B0001:2B - Driver Frontal Stage 1 Deployment Control: Signal Cross Coupled
 If the RCM detects a short between the driver air bag stage 1 circuits and the circuits of another SRS component, it sets this DTC and the DTC of the corresponding SRS component.
  • B0002:2B - Driver Frontal Stage 2 Deployment Control: Signal Cross Coupled
 If the RCM detects a short between the driver air bag stage 2 circuits and the circuits of another SRS component, it sets this DTC and the DTC of the corresponding SRS component.
  • B0004:2B - Driver Knee Bolster Deployment Control: Signal Cross Coupled
 If the RCM detects a short between the driver knee air bag circuits and the circuits of another SRS component, it sets this DTC and the DTC of the corresponding SRS component.
  • B0010:2B - Passenger Frontal Stage 1 Deployment Control: Signal Cross Coupled
 If the RCM detects a short between the passenger air bag stage 1 circuits and the circuits of another SRS component, it sets this DTC and the DTC of the corresponding SRS component.
  • B0011:2B - Passenger Frontal Stage 2 Deployment Control: Signal Cross Coupled
 If the RCM detects a short between the passenger air bag stage 2 circuits and the circuits of another SRS component, it sets this DTC and the DTC of the corresponding SRS component.
  • B0020:2B - Left Side Airbag Deployment Control: Signal Cross Coupled
 If the RCM detects a short between the driver seat side air bag circuits and the circuits of another SRS component, it sets this DTC and the DTC of the corresponding SRS component.
  • B0021:2B - Left Curtain Deployment Control: Signal Cross Coupled
 If the RCM detects a short between the driver side air curtain circuits and the circuits of another SRS component, it sets this DTC and the DTC of the corresponding SRS component.
  • B0028:2B - Right Side Airbag Deployment Control: Signal Cross Coupled
 If the RCM detects a short between the passenger seat side air bag circuits and the circuits of another SRS component, it sets this DTC and the DTC of the corresponding SRS component.
  • B0029:2B - Right Curtain Deployment Control: Signal Cross Coupled
 If the RCM detects a short between the passenger side air curtain circuits and the circuits of another SRS component, it sets this DTC and the DTC of the corresponding SRS component.
  • B0050:2B - Driver Seatbelt Sensor: Signal Cross Coupled
 If the RCM detects a short between the driver safety belt buckle switch circuits and the circuits of another SRS component, it sets this DTC and the DTC of the corresponding SRS component.
  • B0052:2B - Passenger Seatbelt Sensor: Signal Cross Coupled
 If the RCM detects a short between the passenger safety belt buckle switch circuits and the circuits of another SRS component, it sets this DTC and the DTC of the corresponding SRS component.
  • B00B5:2B - Driver Seat Track Position Restraints Sensor: Signal Cross Coupled
 If the RCM detects a short between the driver seat track position sensor circuits and the circuits of another SRS component, it sets this DTC and the DTC of the corresponding SRS component.
  • B1211:2B - Driver Seatbelt Retractor Pretensioner Deployment Control: Signal Cross Coupled
 If the RCM detects a short between the driver safety belt retractor pretensioner circuits and the circuits of another SRS component, it sets this DTC and the DTC of the corresponding SRS component.
  • B1214:2B - Passenger Seatbelt Retractor Pretensioner Deployment Control: Signal Cross Coupled
 If the RCM detects a short between the passenger safety belt retractor pretensioner circuits and the circuits of another SRS component, it sets this DTC and the DTC of the corresponding SRS component.
