WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty, 2013 Ford F-450 Super Duty, 2013 Ford F-350 Super Duty, and 2013 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
On vehicles equipped with a gas engine, the RCM transmits an event notification signal which communicates fuel cut-off status and SRS deployment status to the FPCM. This allows the PCM to initiate fuel cut-off in the event of a crash.
The RCM does not monitor the event notification signal circuit or initiate fuel cut-off on vehicles equipped with a diesel engine.
On vehicles equipped with a gas engine, the RCM monitors the event notification signal circuit for the following faults:
- Short to voltage
- Short to ground
- Open circuit
If a fault is detected, the RCM stores DTC B11D8:12 or B11D8:14 in memory. The airbag warning indicator will not be illuminated if B11D8:12 or B11D8:14 is set.
- DTC B11D8:12 (Restraint Event Notification: Circuit Short to Battery) - A fault is indicated when the RCM senses a short to voltage on the event notification signal circuit for more than 15 seconds.
- DTC B11D8:14 (Restraint Event Notification: Circuit Short to Ground or Open) - A fault is indicated when the RCM senses a short to ground or an open on the event notification signal circuit for more than 15 seconds.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- FPCM
- RCM
