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




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

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

Refer to Wiring Diagram Set 46 (Fusion/Milan/MKZ, Fusion Hybrid, Milan Hybrid, MKZ Hybrid), Supplemental Restraint System for schematic and connector information. Diagrams By Number

Normal Operation

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

The RCM monitors the PAD indicator circuits for the following faults:

- Open circuit
- Short to voltage
- Short to ground
- Faulted PAD indicator

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

- DTC B00D5:11 (Restraint System Passenger Disable Indicator: Circuit Short to Ground) - When the RCM senses a short to ground on the PAD indicator circuit, a fault will be indicated.
- DTC B00D5:12 (Restraint System Passenger Disable Indicator: Circuit Short to Battery) - When the RCM senses a short to voltage on the PAD indicator circuit, a fault will be indicated.
- DTC B00D5:13 (Restraint System Passenger Disable Indicator: Circuit Open) - When the RCM senses an open circuit on the PAD indicator, a fault will be indicated. An open ignition circuit to the PAD indicator can set this DTC.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- PAD indicator
- RCM


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

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) 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.
