Diagnostic Overview

WARNING: This page is about a different car, the 2013 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.

B1414:11, B1414:93, B1419:11 and B1419:93

Refer to OEM Wiring Diagrams - SUPPLEMENTAL RESTRAINT SYSTEM for schematic and connector information.

The RCM monitors the driver front door and passenger second row (C-pillar) side impact sensors and circuits for the following faults:

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

If a fault is detected, the RCM stores DTC B1414:11, B1414:93, B1419:11 or B1419:93 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.

NOTE: A short to ground on either impact sensor feed circuit sets DTCs B1414:11 and B1419:11. A short to voltage on either impact sensor feed circuit sets DTCs B1414:93 and B1419:93.

DTC FAULT TRIGGER CONDITIONS DESCRIPTION

DTC	Description	Fault Trigger Conditions
B1414:11	Driver Side Restraints Sensor 1: Circuit Short to Ground	A fault is indicated when the RCM senses a shorted driver front door side impact sensor, a shorted passenger C-pillar side impact sensor, a short to ground on the driver front door side impact sensor feed circuit or a short to ground on the passenger C-pillar side impact sensor feed circuit.
B1414:93	Driver Side Restraints Sensor 1: No Operation	A fault is indicated when the RCM senses a faulted driver front door side impact sensor, a short to voltage on the feed or return circuit of the driver front door side impact sensor, a short to voltage on the feed or return circuit of passenger C-pillar side impact sensor or an open feed or return circuit of the driver front door side impact sensor.
B1419:11	Passenger Side Restraints Sensor 2: Circuit Short to Ground	A fault is indicated when the RCM senses a shorted driver front door side impact sensor, a shorted passenger C-pillar side impact sensor, a short to ground on the driver front door side impact sensor feed circuit or a short to ground on the passenger C-pillar side impact sensor feed circuit.
B1419:93	Passenger Side Restraints Sensor 2: No Operation	A fault is indicated when the RCM senses a faulted passenger C-pillar side impact sensor, a short to voltage on the feed or return circuit of passenger C-pillar side impact sensor, a short to voltage on the feed or return circuit of the driver front door side impact sensor or an open feed or return circuit of the passenger C-pillar side impact sensor.
