PINPOINT TEST BM : B1414:11, B1414:93, B1419:11 and B1419:93: Notes
Diagnostic Overview
B1414:11, B1414:93, B1419:11 and B1419:93
Refer to 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.
DTC Fault Trigger Conditions
| 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. |
Visual Inspection and Diagnostic Pre-checks
- Inspect for a damaged driver front door side impact sensor
- Inspect for a damaged passenger C-pillar side impact sensor
- Inspect for damaged wiring harness(es)
- Inspect for loose or damaged connectors
