Pinpoint Test P: DTC B0095:11 Or B0095:93
Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS)
Pinpoint Test P: DTC B0095:11 or B0095:93
Refer to Wiring Diagram Set 46, Supplemental Restraint System for schematic and connector information Electrical Diagrams.
Normal Operation
The Restraints Control Module (RCM) checks the RH front impact severity sensor and circuits for the following faults:
- Open circuit
- Short to voltage
- Short to ground
- Faulted RH front impact severity sensor
If a fault is detected, the RCM (Restraints Control Module) stores DTC B0095:11, B0095:81, B0095:93 or B0095:96 in memory and sends a message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.
- DTC B0095:11 (Right Front Restraints Sensor: Circuit Short to Ground)- When the RCM (Restraints Control Module) senses a short to ground on the RH front impact severity sensor feed circuit, a fault is indicated.
- DTC B0095:93 (Right Front Restraints Sensor: No Operation)- When the RCM (Restraints Control Module) senses a faulted sensor, short to voltage or open on either RH front impact severity sensor circuit, a fault is indicated.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- RH front impact severity sensor
- RCM (Restraints Control Module)
PINPOINT TEST P : DTC B0095:11 OR B0095:93
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 (Supplemental Restraint System).
NOTE: Always make sure the correct Supplemental Restraint System (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 (Supplemental Restraint System) component is installed, DTCs may set.
NOTE: The SRS (Supplemental Restraint System) 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 can not be tested using a multi-meter.
