Pinpoint Test - DTC: Y, Coupe
B1415:11, B1415:93, B1418:11, B1418:93, B1424:11
Refer to Wiring Diagrams Cell 46 for schematic and connector information.
Normal Operation and Fault Conditions
The RCM monitors the passenger front door and LH B-pillar side impact sensors and circuits for the following faults:
Open circuit Short to voltage Short to ground Faulted passenger front door side impact sensor Faulted LH B-pillar side impact sensor
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, B1418:93 or B1424:11 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 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.
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 | ||||
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 B-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 LH B-pillar 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 B-pillar side impact sensor, a short to voltage on the feed or return circuit of the LH B-pillar 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 B-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 LH B-pillar side impact sensor feed circuit. | ||
B1418:93 Passenger Side A fault is indicated when the RCM senses a faulted passenger front door side
Restraints Sensor 1: impact sensor, a short to voltage on the feed or return circuit of passenger No Operation front door side impact sensor, a short to voltage on the feed or return circuit of
