Details of the c1297 OBD Code
C1297 indicates a fault with the brake booster pressure sensor circuit in the vehicle.
OBD code C1297 means Brake Lamp Switch Circuit Short to Ground.
This code is triggered by the Body Control Module (BCM) when it detects a short to ground in the brake lamp switch circuit.
The brake lamp switch is a component that signals when the brake pedal is pressed, activating the brake lights.
When a short to ground is detected in this circuit, it can cause issues with brake light operation and potentially affect other vehicle systems that rely on brake switch input.
Mechanic’s Tech Notes
Code C1297 indicates a fault in the brake fluid pressure sensor circuit.
OBDII code C1297 relates to a fault in the brake lamp switch circuit.
To diagnose, use a voltmeter to check power and ground connections at the transmission control module (TCM).
Utilize a scan tool to confirm TCM communication over the Controller Area Network (CAN) network.
Visually inspect wiring harnesses and connectors for damage, focusing on pin connections for signs of corrosion or damage.
If no visible issues are found, consider reprogramming the TCM.
FAQ
