Pinpoint Tests
Pinpoint Test G: DTC B00DF:11, B00DF:12, B00DF:13 or B00DF:1D
Refer to Wiring Diagram Set 46, Supplemental Restraint System for schematic and connector information Diagrams By Number.
Normal Operation
The Passenger Air Bag Deactivation (PAD) switch signals the Restraints Control Module (RCM) by switching a resistance to ground. If the RCM senses 900-1100 ohms in the PAD switch, it enables the passenger air bag and turns off the PAD switch indicator. If the RCM senses 400-600 ohms in the PAD switch, it deactivates the passenger air bag and turns the PAD switch indicator on.
The RCM monitors the status of the PAD switch and circuity. The RCM monitors the PAD switch circuit for the following faults:
- Open circuit
- Short to voltage
- Short to ground
- Faulted PAD switch
The RCM will store DTC B00DF:11, B00DF:12, B00DF:13 or B00DF:1D in memory if any of these conditions are detected. If a fault is detected, the RCM will send a message to the Instrument Panel Cluster (IPC) module to illuminate the air bag warning indicator.
This pinpoint test is intended to diagnose the following:
- Damaged wiring, terminals or connectors
- PAD switch
- RCM
PINPOINT TEST G: DTC B00DF:11, B00DF:12, B00DF:13 or B00DF:1D
NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when making 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 Supplemental Restraint System (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.
