Pinpoint Test Ai: B1417:11, B1417:12, B1417:13

Refer to SUPPLEMENTAL RESTRAINT SYSTEM for schematic and connector information.

Normal Operation and Fault Conditions

The RCM monitors the passenger front impact severity sensor circuits for the following faults:

Open circuit
Short to voltage
Short to ground
Faulted passenger front impact severity sensor

If a fault is detected, the RCM stores DTC B1417:11, B1417:12 or B1417:13 in memory and sends a message to the IPC to illuminate the airbag warning indicator.

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Condition
RCM B1417:11	Passenger Frontal Restraints Sensor: Circuit Short To Ground	A fault is indicated when the RCM senses a short to ground on the passenger front impact severity sensor feed circuit.
RCM B1417:12	Passenger Frontal Restraints Sensor: Circuit Short To Battery	A fault is indicated when the RCM senses a short to battery on the passenger front impact severity sensor feed circuit.
RCM B1417:13	Passenger Frontal Restraints Sensor: Circuit Open	A fault is indicated when the RCM senses an open passenger front impact severity sensor feed circuit.

Visual Inspection and Pre-checks

Inspect for a damaged passenger front impact severity sensor.
Inspect the passenger front impact severity sensor mounting and orientation.
Inspect for damaged wiring harness(es).
Inspect for loose or damaged connectors.

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

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 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 parts catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, Diagnostic Trouble Codes (DTCs) may set.

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

NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
