PINPOINT TEST R : B0001:2B, B0002:2B, B0010:2B, B0011:2B, B0050:2B, B0052:2B, B007E:2B, B007F:2B, B00B5:2B, B1404:2B, B1405:2B, B1407:2B and B1408:2B: Notes
Diagnostic Overview
Diagnostics in this article assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Service Information for information about these practices.
Refer to Supplemental Restraint System , for schematic and connector information.
Normal Operation and Fault Conditions
The RCM continuously monitors all deployable device and sensor circuits for a signal cross coupled (short) between circuits. Signal cross coupled DTCs are present when one or both circuits of a component are shorted to one or both circuits of another component. Signal cross coupled DTCs do not set when the circuits of a single device are shorted together, a different DTC is present (for example, a DTC for circuit resistance below threshold). When a fault is detected, the RCM sends a message to the IPC to illuminate the airbag warning indicator. When a normal loop fault is present (one loop is either shorted to battery/ground, open circuit or low resistance), signal cross coupled diagnostics are not active. Once the normal loop fault is repaired, the signal cross coupled diagnostics resume.
| 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 airbag 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 airbag stage 2 circuits the and 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 airbag 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 airbag stage 2 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. |
| B007E:2B | Driver Seatbelt Pretensioner "C" 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. |
| B007F:2B | Passenger Seatbelt Pretensioner "C" 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. |
| 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. |
| B1404:2B | Driver Side Airbag Deployment Control: Signal Cross Coupled | If the RCM detects a short between the driver side airbag circuits and the circuits of another SRS component, it sets this DTC and the DTC of the corresponding SRS component. |
| B1405:2B | Driver Curtain Deployment Control 1: 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. |
