Pinpoint Test - DTC: X, Coupe
B1414:11, B1414:93, B1419:11, B1419:93, B1427:11, B14EB:11
Refer to Wiring Diagrams Cell 46 for schematic and connector information.
Normal Operation and Fault Conditions
The RCM monitors the driver front door and RH B-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 RH B-pillar side impact sensor
NOTE: A short to ground on either impact sensor feed circuit sets Diagnostic Trouble Codes (DTCs) B1414:11 and B1419:11. A short to voltage on either impact sensor feed or return circuit sets Diagnostic Trouble Codes (DTCs) B1414:93 and B1419:93.
If a fault is detected, the RCM stores DTC B1414:11, B1414:93, B1419:11, B1419:93, B1427:11 or B14EB:11 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.
Some vehicles may be equipped with wiring for pedestrian protection system sensors, although the vehicle is not equipped with the sensors themselves. On these vehicles, if a short to ground condition occurs on the pedestrian protection sensor wiring, short to ground Diagnostic Trouble Codes (DTCs) set for the side impact sensors, in addition to short to ground Diagnostic Trouble Codes (DTCs) for pedestrian protection sensors. Alternatively, if a short to ground condition occurs on the side impact sensor circuits, then pedestrian protection sensor Diagnostic Trouble Codes (DTCs) set as well.
DTC Fault Trigger Conditions
Description | Fault Trigger Conditions | |||
|---|---|---|---|---|
DTC | ||||
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 RH B-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 RH B-pillar side impact sensor feed circuit. If equipped with wiring for pedestrian protection sensors, a short to voltage on those circuits may also set this DTC. | ||
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 RH B-pillar side impact sensor or an open feed or return circuit of the driver front door side impact sensor. | ||
B1419:11 Passenger Side A fault is indicated when the RCM senses a shorted driver front door side
Restraints Sensor 2: impact sensor, a shorted RH B-pillar side impact sensor, a short to ground on Circuit Short to the driver front door side impact sensor feed circuit or a short to ground on Ground the RH B-pillar side impact sensor feed circuit. If equipped with wiring for
pedestrian protection sensors, a short to voltage on those circuits may also
