Pinpoint Test Ya: Driver Door Side Impact Sensor (Third Row Left Hand Side And Second Row Right Hand Side Impact Sensor): Notes
Refer to appropriate Supplemental Restraint System in OEM Wiring Diagrams article, for schematic and connector information.
Normal Operation and Fault Conditions
The RCM monitors the driver door side impact sensor, second row right side impact sensor, third row left side impact sensor and the circuits for each sensor for the following faults:
- Open circuit
- Short to voltage
- Short to ground
- Faulted driver door side impact sensor
- Faulted second row right side impact sensor
- Faulted third row left side impact sensor
NOTE:
A short to ground on either impact sensor feed circuit sets DTC B1414:11, B1416:11 and B1419:11. A short to voltage on either impact sensor feed or return circuit sets DTC B1414:93, B1416:93 and B1419:93.
If a fault is detected, the RCM stores DTC B1414:11, B1414:93, B1416:11, B1416:93, 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 due to a short to voltage on the return circuit of the impact sensor.

Possible Causes
- Wiring, terminals or connectors
- Driver door side impact sensor
- Second row right side impact sensor
- Third row left side impact sensor
- RCM
Visual Inspection and Diagnostic Pre-checks
- Inspect for damaged wiring harness(es).
WARNING:
Incorrect repair techniques or actions can cause an accidental 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.
CAUTION:
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:
Always make sure the correct OCSM 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 OCSM component is installed, 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.
