Normal Operation
The Restraints Control Module (RCM) monitors the passenger front door impact sensor, driver second row side impact sensor (Super Cab and Crew Cab vehicles only) circuits for the following faults:
- Open circuit
- Short to voltage
- Short to ground
- Faulted passenger front door side impact sensor
- Faulted driver second row side impact sensor (Super Cab and Crew Cab vehicles only)
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 air bag 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.
A short to voltage on either impact sensor feed or return circuit sets DTCs B0092:93 and B0096:93 on Super Cab and Crew Cab vehicles.
| DTC Description | Fault Trigger Condition |
|---|---|
|
For Super Cab and Crew Cab vehicles, a fault is indicated when the RCM senses a shorted passenger front door side impact sensor, a shorted driver 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 driver second row side impact sensor feed circuit. |
|
For Super Cab and Crew Cab vehicles, a fault is indicated when the RCM senses a faulted driver second row side impact sensor, a short to voltage on the feed or return circuit of driver second row 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 driver second row side impact sensor. |
|
For Super Cab and Crew Cab vehicles, a fault is indicated when the RCM
senses a shorted passenger front door side impact sensor, a shorted driver 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 driver second row side impact sensor feed circuit. For regular cab vehicles, a fault is indicated when the RCM senses a shorted passenger front door side impact sensor or a short to ground on the passenger front door side impact sensor feed circuit. |
|
For Super Cab and Crew Cab vehicles, 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 driver second row side impact sensor or an open feed or return circuit of the passenger front door side impact sensor. For regular cab vehicles, 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 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
- Passenger front door side impact sensor
- Driver second row side impact sensor
- RCM
