Pinpoint Tests
Pinpoint Test N: DTCs B0092:11, B0092:93, B0096:11 and B0096:93
Refer to Wiring Diagram Set 46 (Escape/Mariner, Escape Hybrid/Mariner Hybrid), Supplemental Restraint System for schematic and connector information. Diagrams By Number
Normal Operation
The Restraints Control Module (RCM) monitors the driver second row C-pillar and passenger first row B-pillar side impact sensors and circuits for the following faults:
- Open circuit
- Short to voltage
- Short to ground
- Faulted driver second row C-pillar side impact sensor
- Faulted passenger first row B-pillar side impact sensor
If a fault is detected, the RCM will store DTC B0092:11, B0092:93, B0096:11 or B0096:93 in memory and send a message to the Instrument Cluster (IC) module 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 will be stored in memory. A Continuous Memory Diagnostic Trouble Code (CMDTC) no operation (failure type status :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 will set DTCs B0092:11 and B0096:11.
A short to voltage on either impact sensor feed or return circuit will set DTCs B0092:93 and B0096:93.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Driver second row C-pillar side impact sensor
- Passenger first row B-pillar side impact sensor
- RCM
PINPOINT TEST N: DTCs B0092:11, B0092:93, B0096:11 AND B0096:93
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.
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:Supplemental Restraint System (SRS) components should only be disconnected or reconnected 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.
