Details of the c107d OBD Code
Code C107D indicates a fault with the park brake switch circuit in the vehicle.
OBD code C107D indicates a fault with the park brake switch circuit.
This code is triggered by the body control module (BCM) when it detects an issue with the park brake switch circuit.
The park brake switch is part of the parking brake system and is used to inform the BCM when the parking brake is engaged or disengaged.
When the BCM detects a fault with this circuit, it will set code C107D and illuminate the warning light on the dashboard to alert the driver of the issue.
Mechanic’s Tech Notes
This fault code indicates an issue with the park brake control module.
OBDII code C107D typically indicates a problem with the Transmission Control Module (TCM) power supply.
To diagnose this, use a multimeter to check the TCM’s power and ground connections for proper voltage levels.
Additionally, utilize a scan tool to confirm if the TCM is communicating over the Controller Area Network (CAN) network.
If the TCM is unresponsive, reprogramming or reflashing it may be necessary.
Visually inspect the wiring harness and connectors for any damage, and ensure connector pins are not broken, bent, pushed out, or corroded.
This thorough inspection can help pinpoint the root cause of the issue for an effective repair.
