PINPOINT TEST P : DTCs B1414:11, B1414:93, B1419:11 AND B1419:93: Notes
Diagnostic Overview
Diagnostics in this article assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Service Information for information about these practices.
Refer to Supplemental Restraint System , for schematic and connector information.
Normal Operation and Fault Conditions
The RCM continuously monitors the driver front door and RH 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 RH 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.
When the feed circuit of either impact sensor is shorted to voltage, an invalid data received fault (failure type :81) may also be present for both sensors.
A short to voltage on either impact sensor feed or return circuit sets DTCs B1414:93 and B1419:93.
| DTC | Description | Fault Trigger Condition |
|---|---|---|
| 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 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 RH 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 the RH 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 RH 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 RH 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 RH C-pillar side impact sensor, a short to voltage on the feed or return circuit of the RH 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 RH C-pillar side impact sensor. |
