Pinpoint Test - DTC: B B00D5:11, B00D5:12 and B00D5:13 - Vehicles without Centerstack Display

WARNING: This page is about a different car, the 2019 Ford F-550 Super Duty, 2019 Ford F-450 Super Duty, 2019 Ford F-350 Super Duty, and 2019 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

REFER to Supplemental Restraint System for schematic and connector information.

Normal Operation and Fault Conditions

The RCM briefly activates each LED in the PAD indicator to prove-out and verify to the occupants correct functional operation of the PAD indicator.

The RCM monitors the PAD indicator power supply and "OFF" LED circuits for the following faults:

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

If a fault is detected, the RCM stores DTC B00D5:12 or B00D5:14 in memory and sends a message to the IPC to illuminate the airbag warning indicator.

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Conditions
B00D5:11	Restraint System Passenger Disable Indicator: Circuit Short to Ground	A fault is indicated when the RCM senses a short to ground on the PAD indicator "OFF" LED circuit.
B00D5:12	Restraint System Passenger Disable Indicator: Circuit Short to Battery	A fault is indicated when the RCM senses a short to voltage on the PAD indicator "OFF" LED circuit.
B00D5:13	Restraint System Passenger Disable Indicator: Circuit Open	A fault is indicated when the RCM senses an open circuit on the PAD indicator "OFF" LED circuit. An open on the ignition voltage supply circuit to the PAD indicator also sets this DTC.

PINPOINT TEST A : B00D5:11, B00D5:12 AND B00D5:13

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.
NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to the connector.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
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.
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.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
