Pinpoint Test Z: Passenger Door And Left C-Pillar Side Impact Sensor Super Cab And Super Crew: 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 passenger door and the second row left side impact sensors and circuits for the following faults:

Open circuit
Short to voltage
Short to ground
Faulted passenger door side impact sensor
Faulted second row left side impact sensor

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.

PPT Z RCM DTC FAULT TRIGGER CONDITIONS

DTC	Description	Fault Trigger Conditions
B0092:81	Left Side Restraints Sensor 2: Invalid Serial Data Received	Sets when the RCM senses a faulted left hand C-pillar side impact sensor or an open from the left hand C-pillar side impact sensor circuits.
B0096:11	Right Side Restraints Sensor 1: Circuit Short to Ground	Sets when the RCM senses a shorted passenger door side impact sensor, a shorted left hand C-pillar side impact sensor, a short to ground from the passenger door side impact sensor feed circuit or a short to ground from the left hand C pillar side impact sensor feed circuit.
B0096:81	Right Side Restraints Sensor 1: Invalid Serial Data Received	Sets when the RCM senses a faulted passenger door side impact sensor or an open from the passenger door side impact sensor circuits.
B0096:93	Right Side Restraints Sensor 1: No Operation	Sets when the RCM senses a faulted left hand C-pillar side impact sensor or passenger door side impact sensor, or a short to voltage from the feed or return circuit of the left hand C-pillar side impact sensor or passenger door side impact sensor.

Possible Causes

Wiring, terminals or connectors
Passenger door side impact sensor
Second 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.
