Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS)

Pinpoint Test AC: DTCs B00D5:11, B00D5:12 and B00D5:13

Normal Operation

The Restraints Control Module (RCM) briefly activates the Passenger Air Bag Deactivation (PAD) indicator to prove-out and verify to the fault occupants correct functional operation of the PAD (Passenger Air Bag Deactivation) indicator.

The RCM (Restraints Control Module) monitors the PAD (Passenger Air Bag Deactivation) indicator circuits for the following faults:

- Open circuit

- Short to voltage

- Short to ground

- Faulted PAD (Passenger Air Bag Deactivation) indicator

If a fault is detected, the RCM (Restraints Control Module) will store DTC B00D5:11, B00D5:12 or B00D5:13 in memory and send a message to the Instrument Cluster (IC) module to illuminate the air bag warning indicator.

- DTC B00D5:11 (Restraint System Passenger Disable Indicator: Circuit Short to Ground)- When the RCM (Restraints Control Module) senses a short to ground on the PAD (Passenger Air Bag Deactivation) indicator circuit, a fault will be indicated.

- DTC B00D5:12 (Restraint System Passenger Disable Indicator: Circuit Short to Battery)- When the RCM (Restraints Control Module) senses a short to voltage on the PAD (Passenger Air Bag Deactivation) indicator circuit, a fault will be indicated.

- DTC B00D5:13 (Restraint System Passenger Disable Indicator: Circuit Open)- When the RCM (Restraints Control Module) senses an open circuit on the PAD (Passenger Air Bag Deactivation) indicator, a fault will be indicated. An open ignition circuit to the PAD (Passenger Air Bag Deactivation) indicator can set this DTC.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors

- PAD (Passenger Air Bag Deactivation) indicator

- HVAC module (without navigation)

- Front Controls Interface Module (FCIM) (with navigation)

- RCM (Restraints Control Module)

PINPOINT TEST AC : DTCs B00D5:11, B00D5:12 AND B00D5:13

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 (Supplemental Restraint System).

NOTE: Always make sure the correct SRS (Supplemental Restraint System) 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 (Supplemental Restraint System) component is installed, DTCs may set.

NOTE: The SRS (Supplemental Restraint System) must be fully operational and free of faults before releasing the vehicle to the customer.
