Pinpoint Test V - DTC: B1415:11, B1415:93, B1418:11 and B1418:93

Refer to Supplemental Restraint System for schematic and connector information.

Normal Operation and Fault Conditions 

The RCM monitors the passenger front door and LH C-pillar side impact sensors and circuits for the following faults:

• Open circuit
• Short to voltage
• Short to ground
• Faulted passenger front door side impact sensor
• Faulted LH C-pillar side impact sensor

If a fault is detected, the RCM stores DTC B1415:11, B1415:93, B1418:11 or B1418:93 in memory and sends a message to the IPC to illuminate the airbag 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.

DTC Fault Trigger Conditions 

DTC	Description	Fault Trigger Conditions
B1415:11	Driver Side Restraints Sensor 2: Circuit Short to Ground	A fault is indicated when the RCM senses a shorted passenger door side impact sensor, a shorted second row LH side impact sensor, a short to ground on the passenger front door side impact sensor feed circuit or a short to ground on the second row LH side impact sensor feed circuit.
B1415:93	Driver Side Restraints Sensor 2: No Operation	A fault is indicated when the RCM senses a faulted second row LH side impact sensor, a short to voltage on the feed or return circuit of the second row LH side impact sensor, a short to voltage on the feed or return circuit of passenger front door side impact sensor or an open feed or return circuit of the passenger front door impact sensor.
B1418:11	Passenger Side Restraints Sensor 1: Circuit Short to Ground	A fault is indicated when the RCM senses a shorted passenger front door side impact sensor, a shorted second row LH side impact sensor, a short to ground on the passenger front door side impact sensor feed circuit or a short to ground on the second row LH side impact sensor feed circuit.
B1418:93	Passenger Side Restraints Sensor 1: No Operation	A fault is indicated when the RCM senses a faulted passenger front door side impact sensor, a short to voltage on the feed or return circuit of passenger front door side impact sensor, a short to voltage on the feed or return circuit of the second row LH side impact sensor or an open feed or return circuit of the passenger front door side impact sensor.

Possible Causes 

• Wiring, terminals or connectors
• Passenger front door side impact sensor

Visual Inspection and Diagnostic Pre-checks 

• Inspect for damaged wiring harness(es).

PINPOINT TEST A : B1415:11, B1415:93, B1418:11 AND B1418:93 

• 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: 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: 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: 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.
• A1 RETRIEVE RCM (RESTRAINTS CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)
