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 continuously monitors the passenger airbag stage 1 and circuits for the following faults:

If a fault is detected, the RCM stores DTC B0010:11, B0010:12, B0010:13 or B0010:1A in memory and sends a message to the IPC to illuminate the airbag warning indicator.

The RCM analyzes the deployment loop resistance and uses this measurement in combination with an age correction factor to determine if a fault exists. The value displayed in the PID is the deployment loop resistance as measured by the RCM. If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. The RCM fault trigger threshold may vary as the vehicle ages. Small variations in resistance can occur due to the effect of road vibrations on terminal fit and/or temperature changes. These variables can result in an intermittent fault. For this reason, the test will requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses a process of elimination to diagnose each part of the deployment loop circuit including:

DTC DESCRIPTION

DTC Description Fault Trigger Condition
  • B0010:11 - Passenger Frontal Stage 1 Deployment Control: Circuit Short to Ground
 When the RCM senses a short to ground on either passenger airbag stage 1 circuit, a fault is indicated.
  • B0010:12 - Passenger Frontal Stage 1 Deployment Control: Circuit Short to Battery
 When the RCM senses a short to voltage on either passenger airbag stage 1 circuit, a fault is indicated.
  • B0010:13 - Passenger Frontal Stage 1 Deployment Control: Circuit Open
 When the RCM measures greater than the desired resistance range between passenger airbag stage 1 circuits, a fault is indicated.
  • B0010:1A - Passenger Frontal Stage 1 Deployment Control: Circuit Resistance Below Threshold
 When the RCM measures less than the desired resistance range between passenger airbag stage 1 circuits, a fault is indicated.

This pinpoint test is intended to diagnose the following:
