Pinpoint Test M: DTCs B0091:11, B0091:93, B0097:11 and B0097:93

Refer to Wiring Diagram Set 46, Supplemental Restraint System for schematic and connector information. Diagrams By Number

Normal Operation

The Restraints Control Module (RCM) monitors the driver front door impact sensor and passenger second row side impact sensor (SuperCab and SuperCrew vehicles only) circuits for the following faults:

- Open circuit
- Short to voltage
- Short to ground
- Faulted driver front door side impact sensor
- Faulted passenger second row side impact sensor (SuperCab and SuperCrew vehicles only)

If a fault is detected, the RCM stores DTC B0091:11, B0091:93, B0097:11 or B0097:93 in memory and sends a message to the Instrument Panel Cluster (IPC) to illuminate the air bag 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.

NOTE: A short to ground on either impact sensor feed circuit sets DTCs B0091:11 and B0097:11 on SuperCab and SuperCrew vehicles.

A short to voltage on either impact sensor feed or return circuit sets DTCs B0091:93 and B0097:93 on SuperCab and SuperCrew vehicles.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Driver front door side impact sensor
- Passenger second row side impact sensor
- RCM

PINPOINT TEST M: DTCs B0091:11, B0091:93, B0097:11 AND B0097:93

WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy(R) and cause serious personal injury or death.

NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure to use the correct probe adapter(s) may damage 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. Inspection and Verification

NOTE: Only disconnect or reconnect Supplemental Restraint System (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: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

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 Catalog Advantage(TM) or equivalent to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.

NOTE: Do not probe any impact sensor. The impact sensor cannot be tested using a multi-meter.
