WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
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. |
