Pinpoint Test XB: Driver Door And Right C-Pillar Side Impact Sensor (Including Component Internal Failure): 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 and the second row right side impact sensors and circuits 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
NOTE:
The second row right side impact sensor also known as the right C-pillar side impact sensor. If a fault is detected, the RCM stores DTC B1414:11, B1414:12, B1414:13, B1414:96, B1419:11, B1419:12, B1419:13 or B1419:96 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 CMDTC no operation (failure type: 93) can be set by a short to voltage on the return circuit of the impact sensor.
When the feed circuit of either impact sensor is shorted to voltage, an invalid data received fault (failure type :81) may also be present for both sensors.

PPT X RCM DTC FAULT TRIGGER CONDITIONS
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B0091:11 | Left Side Restraints Sensor 1: Circuit Short to Ground | Sets when the RCM senses a shorted driver door side impact sensor, a shorted right C-pillar side impact sensor, a short to ground from the driver door side impact sensor feed circuit or a short to ground from the right C-pillar side impact sensor feed circuit. |
| B0091:81 | Left Side Restraints Sensor 1: Invalid Serial Data Received | Sets when the RCM senses a faulted right C-pillar side impact sensor or driver door side impact sensor, or a short to voltage from the feed or return circuit of the right C-pillar side impact sensor or driver door side impact sensor. |
| B0091:93 | Left Side Restraints Sensor 1: No Operation | Sets when the RCM senses a faulted right C-pillar side impact sensor or driver door side impact sensor, or a short to voltage from the feed or return circuit of the right C-pillar side impact sensor or driver door side impact sensor. |
| B0097:81 | Right Side Restraints Sensor 2: Invalid Serial Data Received | Sets when the RCM senses a faulted right C-pillar side impact sensor or an open right C-pillar side impact sensor circuit. |
Possible Causes
- Wiring, terminals or connectors
- Driver door side impact sensor
- Second row right side impact sensor
- RCM
Visual Inspection
- 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.
