PINPOINT TEST P : DTCs B1414:11, B1414:93, B1419:11 AND B1419:93: Notes

WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.

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:

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.

NOTE: A short to ground on either impact sensor feed circuit sets DTCs B1414:11 and B1419:11.

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.
