Normal Operation

WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty, 2013 Ford F-450 Super Duty, 2013 Ford F-350 Super Duty, and 2013 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

The RCM monitors the driver front door impact sensor, passenger C-pillar side impact sensor (SuperCab and Crew Cab only) and circuits for the following faults:

If a fault is detected, the RCM stores DTC B0091:11, B0091:93, B0097:11 or B0097:93 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 B0091:11 and B0097:11 on SuperCab and Crew Cab vehicles.
A short to voltage on either impact sensor feed circuit sets DTCs B0091:93 and B0097:93 on SuperCab and Crew Cab vehicles.
DTC DESCRIPTION

DTC Description Fault Trigger Condition
  • B0091:11 - Left Side Restraints Sensor 1: Circuit Short to Ground
 For SuperCab and Crew Cab vehicles, when the RCM senses a shorted driver front door side impact sensor, a shorted passenger second row 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 second row side impact sensor feed circuit, a fault is indicated. For regular cab vehicles, when the RCM senses a shorted driver front door side impact sensor or a short to ground on the driver front door side impact sensor feed circuit, a fault is indicated.
  • B0091:93 - Left Side Restraints Sensor 1: No Operation
 For SuperCab and Crew Cab vehicles, 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 second row side impact sensor or an open feed or return circuit of the driver front door side impact sensor, a fault is indicated. For regular cab vehicles, 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 or an open feed or return circuit of the driver front door side impact sensor, a fault is indicated.
  • B0097:11 - Right Side Restraints Sensor 2: Circuit Short to Ground
 For SuperCab and Crew Cab vehicles, when the RCM senses a shorted driver front door side impact sensor, a shorted passenger second row 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 second row side impact sensor feed circuit, a fault is indicated.
  • B0097:93 - Right Side Restraints Sensor 2: No Operation
 For SuperCab and Crew Cab vehicles, when the RCM senses a faulted passenger second row side impact sensor, a short to voltage on the feed or return circuit of passenger second row 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 second row side impact sensor, a fault is indicated.

This pinpoint test is intended to diagnose the following:
