Details of the c1480 OBD Code
Code C1480 relates to an issue with the brake pedal position sensor circuit.
OBD code C1480 means Brake Pedal Switch Circuit High Voltage.
This code is triggered by the Body Control Module (BCM) when it detects a high voltage signal from the brake pedal switch circuit.
The brake pedal switch is part of the brake light circuit and is used to inform the BCM when the brake pedal is pressed.
A high voltage signal can indicate a fault in the brake pedal switch or its wiring, potentially causing issues with brake light operation or other safety systems that rely on brake pedal status.
Mechanic’s Tech Notes
Code C1480 indicates an issue with the brake pedal position sensor circuit.
To diagnose and fix OBDII code C1480, start by checking the Transmission Control Module (TCM) power and ground using a multimeter.
Verify TCM communication over the Controller Area Network (CAN) using a scan tool.
If the TCM does not respond, reprogramming or reflashing may be necessary.
Additionally, visually inspect the wiring harness and connectors for any damage, and ensure connector pins are not broken, bent, pushed out, or corroded.
Address any issues found during the inspection to resolve the C1480 fault code.
