Pinpoint Test A - DTC: B0001:11, B0001:12, B0001:13 and B0001:1A

WARNING: This page is about a different car, the 2018 Ford F-550 Super Duty, 2018 Ford F-450 Super Duty, 2018 Ford F-350 Super Duty, and 2018 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

Normal Operation and Fault Conditions 

The RCM continuously monitors the driver airbag circuits for the following faults:

If a fault is detected, the RCM stores DTC B0001:11, B0001:12, B0001:13 or B0001:1A in memory and sends a message to the IPC to illuminate the airbag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance 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. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test 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 process of elimination to diagnose each part of the deployment loop circuit including:

DTC Fault Trigger Conditions 

DTC Description Fault Trigger Conditions
B0001:11 Driver Frontal Stage 1 Deployment Control: Circuit Short to Ground A fault is indicated when the RCM senses a short to ground on either driver airbag circuit for approximately 6 seconds.
B0001:12 Driver Frontal Stage 1 Deployment Control: Circuit Short to Battery A fault is indicated when the RCM senses a short to voltage on either driver airbag circuit for approximately 6 seconds.
B0001:13 Driver Frontal Stage 1 Deployment Control: Circuit Open A fault is indicated when the RCM measures more than the desired resistance range between driver airbag circuits for approximately 6 seconds.
B0001:1A Driver Frontal Stage 1 Deployment Control: Circuit Resistance Below Threshold A fault is indicated when the RCM measures less than the desired resistance range between driver airbag circuits for approximately 6 seconds.

Possible Causes 

Visual Inspection and Diagnostic Pre-checks 

PINPOINT TEST A : B0001:11, B0001:12, B0001:13 AND B0001:1A 

  1. WARNING: Incorrect repair techniques or actions can cause an accidental Supplemental Restraint System (SRS) deployment. Never compromise or depart from these instructions. Failure to precisely follow all instructions could result in serious personal injury from an accidental deployment.
  2. NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to the connector.
  3. NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
  4. NOTE: Only disconnect or reconnect SRS components when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS.
  5. NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the Ford parts catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, Diagnostic Trouble Codes (DTCs) may set.
  6. NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
