Diagnostic Overview
WARNING: This page is about a different car, the 2013 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
B1415:11, B1415:93, B1418:11 and B1418:93
Refer to OEM Wiring Diagrams - SUPPLEMENTAL RESTRAINT SYSTEM for schematic and connector information.
The RCM monitors the passenger front door (first row) and driver C-pillar (second row) 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 driver C-pillar side impact sensor
If a fault is detected, the RCM stores DTC B1415:11, B1415:93, B1418:11 or B1418:93 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.
NOTE:
A short to ground on either impact sensor feed circuit sets DTCs
B1415:11 and B1418:11. A short to voltage on either impact sensor feed circuit sets DTCs
B1415:93 and B1418:93.
DTC FAULT TRIGGER CONDITIONS DESCRIPTION
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B1415:11 | Driver Side Restraints Sensor 2: Circuit Short to Ground | 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. |
| B1415:93 | Driver Side Restraints Sensor 2: No Operation | 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. |
| 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 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. |
| B1418:93 | Passenger Side Restraints Sensor 1: No Operation | 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. |
