Pinpoint Test U - DTC: B1414:11, B1414:93, B1419:11, B1419:93
Refer to Supplemental Restraint System for schematic and connector information.
Normal Operation and Fault Conditions
The RCM monitors the driver front door and RH B-pillar (vehicles without second row seat) or RH C-pillar (vehicles with second row seat) side impact sensors and circuits for the following faults:
- Open circuit
- Short to voltage
- Short to ground
- Faulted driver front door side impact sensor
- Faulted RH B-pillar side impact sensor (vehicles without second row seat)
- Faulted RH C-pillar side impact sensor (vehicles with second row seat)
If a fault is detected, the RCM stores DTC B1414:11, B1414:93, B1419:11 or B1419:93 in memory and sends a message to the IPC to illuminate the airbag warning indicator.
The RCM communicates with each impact sensor. If the RCM is unable to communicate with the sensor, a DTC is stored in memory. A Continuous Memory Diagnostic Trouble Code (CMDTC) no operation (failure type: 93) can be set by a short to voltage on the return circuit of the impact sensor.

PINPOINT TEST A : B1414:11, B1414:93, B1419:11, B1419:93
- 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: 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: 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.
- NOTE: Do not probe any impact sensor. The impact sensor cannot be tested using a multi-meter.
