B11D8:11, B11D8:12, B11D8:13


Refer to Wiring Diagrams Cell 46 for schematic and connector information.

Normal Operation and Fault Conditions

The RCM transmits an event notification signal which communicates fuel cutoff 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 ground
  • Open circuit

If a fault is detected, the RCM stores DTC B11D8:11, B11D8:12 or B11D8:13 in memory. The airbag warning indicator does not illuminate if B11D8:11, B11D8:12 or B11D8:13 is set.


  DTC Fault Trigger Conditions


  DTC Description Fault Trigger Conditions
B11D8:11 Restraint Event Notification: Short to Ground A fault is indicated when the RCM senses a short to ground on the event notification signal circuit for more than 15 seconds.
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.
B11D8:13 Restraint Event Notification: Circuit Open A fault is indicated when the RCM senses an open on the event notification signal circuit for more than 15 seconds.

Possible Causes

  • Wiring, terminals or connectors
  • BCM
  • RCM

PINPOINT TEST A: B11D8:11, B11D8:12, B11D8:13
  WARNING: Incorrect repair techniques or actions can cause an accidental Supplemental Restraint System (SRS) deployment. Never compromise or depart from these instructions. Failure to precisely follow all instructions could result in serious personal injury from an accidental deployment.
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to the connector.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
NOTE: Only disconnect or reconnect SRS components when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS .
NOTE: Install new components only when directed to do so in the pinpoint test.
NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the Ford parts catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, Diagnostic Trouble Codes (DTCs) may set.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
