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 the passenger safety belt buckle switch and circuits for the following faults:
- Open circuit
- Short to voltage
- Short to ground
- Current out of range
- Faulted passenger safety belt buckle switch
If a fault is detected, the RCM stores DTC B0052:11, B0052:12, B0052:13 or B0052:1D in memory and sends a message to the IPC to illuminate the airbag warning indicator.

|---|---|---|
| B0052:11 | Passenger Seatbelt Sensor: Circuit Short to Ground | A fault is indicated when the RCM senses a short to ground on the passenger safety belt buckle switch circuit for more than 6 seconds. |
| B0052:12 | Passenger Seatbelt Sensor: Circuit Short to Battery | A fault is indicated when the RCM senses a short to voltage on the passenger safety belt buckle switch circuit for more than 6 seconds. |
| B0052:13 | Passenger Seatbelt Sensor: Circuit Open | A fault is indicated when the RCM senses an open on either passenger safety belt buckle switch circuit for more than 6 seconds. |
