Pinpoint Test V, Crew Cab/Super Cab - DTC: B1415:11, B1415:93, B1418:11 and B1418:93

WARNING: This page is about a different car, the 2018 Ford F-550 Super Duty, 2018 Ford F-450 Super Duty, 2018 Ford F-350 Super Duty, and 2018 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

Refer to Supplemental Restrain System for schematic and connector information.

Normal Operation and Fault Conditions 

The RCM monitors the passenger front door and LH second row side impact sensors and circuits for the following faults:

NOTE: A short to ground on either impact sensor feed circuit sets DTC B1415:11 and B1418:11. A short to voltage on either impact sensor feed or return circuit sets DTC B1415:93 and B1418:93.

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 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 LH second row side impact sensor, a short to ground on the passenger front door side impact sensor feed circuit or a short to ground on the LH second row side impact sensor feed circuit.
B1415:93 Driver Side Restraints Sensor 2: No Operation A fault is indicated when the RCM senses a faulted LH second row side impact sensor, a short to voltage on the feed or return circuit of the LH second row 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 LH second row side impact sensor, a short to ground on the passenger front door side impact sensor feed circuit or a short to ground on the LH second row 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 LH second row side impact sensor or an open feed or return circuit of the passenger front door side impact sensor.

Possible Causes 

Visual Inspection and Diagnostic Pre-checks 

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

  1. WARNING: Incorrect repair techniques or actions can cause an accidental Supplemental Restraint System (SRS) deployment. Never compromise or depart from these instructions. Failure to precisely follow all instructions could result in serious personal injury from an accidental deployment.
  2. NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to the connector.
  3. NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
  4. 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.
  5. 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.
  6. NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
  7. NOTE: Do not probe any impact sensor. The impact sensor cannot be tested using a multi-meter.

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

    • Ignition ON.

    • Using a diagnostic scan tool, perform RCM self-test.

    Were any Diagnostic Trouble Codes (DTCs) retrieved on-demand during self-test? 

    Yes  The fault(s) cannot be cleared until corrected and the Diagnostic Trouble Codes (DTCs) are no longer retrieved on-demand during self-test. If DTC U3003:16 or U3003:17 is also retrieved on-demand, DIAGNOSE those Diagnostic Trouble Codes (DTCs) first. Refer to: Pinpoint Test - DTC: AG . If DTC U3003:16 or U3003:17 is not retrieved on-demand during self-test, DIAGNOSE the impact sensor Diagnostic Trouble Codes (DTCs). For DTC B1415:11
    AND  B1418:11, GO to A2
