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 front impact severity sensor and circuits for the following faults:
- Open circuit
- Short to voltage
- Short to ground
- Faulted front impact severity sensor
If a fault is detected, the RCM stores DTC B1413:11 or B1413:93 in memory and sends a message to the IPC to illuminate the airbag warning indicator.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B1413:11 | Driver Frontal Restraints Sensor: Circuit Short to Ground | A fault is indicated when the RCM senses a short to ground on the LH front impact severity sensor feed circuit. |
| B1413:93 | Driver Frontal Restraints Sensor: No Operation | A fault is indicated when the RCM senses a faulted LH front impact severity sensor, a short to voltage on the sensor feed circuit, an open sensor feed or an open sensor return circuit. |
