Normal Operation
WARNING: This page is about a different car, the 2014 Lincoln MKX and 2014 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
The Restraints Control Module (RCM) monitors the driver second row (C-pillar) and passenger front door side impact sensors and circuits for the following faults:
- Open circuit
- Short to voltage
- Short to ground
- Faulted driver C-pillar side impact sensor
- Faulted passenger front door side impact sensor
If a fault is detected, the RCM stores DTC B0092:11, B0092:93, B0096:11 or B0096:93 in memory and sends a message to the Instrument Panel Cluster (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.
NOTE:
A short to ground on either impact sensor feed circuit sets DTCs B0092:11 and B0096:11.
A short to voltage on either impact sensor feed or return circuit sets DTCs B0092:93 and B0096:93.
A short to voltage on either impact sensor feed or return circuit sets DTCs B0092:93 and B0096:93.
DTC DESCRIPTION
| DTC Description | Fault Trigger Condition |
|---|---|
|
A fault is indicated when the RCM senses a shorted passenger door side impact sensor, a shorted driver C-pillar side impact sensor, a short to ground on the passenger front door side impact sensor feed circuit or a short to ground on the driver C-pillar side impact sensor feed circuit. |
|
A fault is indicated when the RCM senses a faulted driver C-pillar side impact sensor, a short to voltage on the feed or return circuit of the driver C-pillar side impact sensor, a short to voltage on the feed or return circuit of the passenger front door side impact sensor or an open feed or return circuit of the passenger front door impact sensor. |
|
A fault is indicated when the RCM senses a shorted passenger front door side impact sensor, a shorted driver C-pillar side impact sensor, a short to ground on the passenger front door side impact sensor feed circuit or a short to ground on the driver C-pillar side impact sensor feed circuit. |
|
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 the passenger front door side impact sensor, a short to voltage on the feed or return circuit of the driver C-pillar side impact sensor or an open feed or return circuit of the passenger front door side impact sensor. |
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Driver (C-pillar) side impact sensor
- Passenger front door side impact sensor
- RCM
