Pinpoint Test D: DTCs B0005:11, B0005:12, B0005:13 And B0005:1A
Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS)
Pinpoint Test D: DTCs B0005:11, B0005:12, B0005:13 and B0005:1A
Normal Operation
The Restraints Control Module (RCM) continuously monitors the deployable steering column and circuits for the following faults:
- Resistance out of range
- Unexpected voltage
- Short to ground
- Faulted deployable steering column
If a fault is detected, the RCM will store DTC B0005:11, B0005:12, B0005:13 or B0005:1A in memory and send a message to the Instrument Cluster (IC) module to illuminate the air bag 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 require 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 time of diagnosis. Following this direction will help make sure that minor changes in resistance do not create a repeat concern. This test will use a process of elimination to diagnose each part of the deployment loop circuit including:
- Wiring
- Connections
- Deployable steering column
- RCM
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Deployable steering column
- RCM
PINPOINT TEST D: DTCs B0005:11, B0005:12, B0005:13 AND B0005:1A
WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy(R) and cause serious personal injury or death.
WARNING: Never probe the electrical connectors on air bag, Safety Canopy(R) or side air curtain modules. Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.
Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test. Inspection and Verification
NOTE: Supplemental Restraint System (SRS) components should only be disconnected or reconnected when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS.
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 Catalog Advantage(TM) or equivalent to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
