Pinpoint Test U: B14ED:12, B14ED:14

Refer to SUPPLEMENTAL RESTRAINT SYSTEM 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 door control modules. When the door latch control modules receive an event notification signal which indicates a crash, they enter a crash unlock mode that allows the doors to unlatch from the inside or outside door latch release switches after approximately 10 seconds.

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 B14ED:12 or B14ED:14 in memory. The airbag warning indicator does not illuminate if B14ED:12 or B14ED:14 is set. If DCME or DCMF sets DTC B1262:92 , diagnose the RCM faults.

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Condition
DCME B1262:92	Crash Input Mismatch - CAN Active, Hardware Inactive: Performance or Incorrect Operation	This DTC sets when the DCME senses a fault on the event notification signal circuit 2.
DCMF B1262:92	Crash Input Mismatch - CAN Active, Hardware Inactive: Performance or Incorrect Operation	This DTC sets when the DCMF senses a fault on the event notification signal circuit 2.
RCM B14ED:12	Restraint Event Notification 2: 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.
RCM B14ED:14	Restraint Event Notification 2: 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.

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.

NOTE: 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.
