Details of the c0253 OBD Code
Code C0253 indicates a malfunction in the ABS motor relay circuit.
OBD code C0253 means that the ABS Module has detected a malfunction in the ABS Motor Relay Circuit.
This code is triggered by the ABS Module when it detects an issue with the relay circuit that controls the ABS motor.
The ABS motor relay circuit is responsible for controlling the operation of the ABS motor, which is a crucial component of the ABS system.
When the ABS Module detects a fault in this circuit, it will trigger the C0253 fault code to indicate that there is a problem with the ABS motor relay circuit.
Mechanic’s Tech Notes
Code C0253 indicates a malfunction in the ABS motor relay circuit.
OBDII code C0253 indicates a fault with the TCM power supply.
To diagnose, use a voltmeter to check TCM power and ground connections for proper voltage levels.
Utilize a scan tool to confirm TCM communication over the CAN network.
Visually inspect wiring harnesses and connectors for any damage, and ensure connector pins are not broken, bent, pushed out, or corroded.
If all checks out, consider reprogramming the TCM.
