Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Pinpoint Test PB: Event Notification Signal (Equipped With BCM-C And Fuel Pump Control Module): Notes
Refer to appropriate Supplemental Restraint System in OEM Wiring Diagrams article, for schematic and connector information.
Normal Operation and Fault Conditions
The RCM transmits an event notification signal which communicates crash status and SRS deployment status to the BCM. When the BCM receives an event notification signal which indicates a crash, it initiates fuel cut-off.
The RCM monitors the event notification signal circuit for the following faults:
- Short to voltage
- 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 does not illuminate if B11D8:12 or B11D8:14 is set.
PPT P RCM DTC FAULT TRIGGER CONDITIONS
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B11D8:12 | Restraint Event Notification: Circuit Short to Battery | Sets when the RCM senses a short to voltage from the event notification signal circuit for more than 12 seconds. |
| B11D8:14 | Restraint Event Notification: Circuit Short to Ground or Open | Sets when the RCM senses a short to ground or an open from the event notification signal circuit for more than 12 seconds. |
