Details of the Toyota c0246 OBD Code
Toyota fault code C0246 relates to a problem with the motor circuit for the ABS pump.
OBD code C0246 for Toyota refers to an issue with the right front wheel speed sensor signal.
This code is triggered by the AntiLock Brake System (ABS) module when it detects a problem with the signal coming from the right front wheel speed sensor.
The ABS module uses this sensor to monitor the speed of the right front wheel to help prevent wheel lockup during braking.
If the sensor signal is erratic or missing, the ABS module will set a C0246 fault code.
Mechanic’s Tech Notes
For Toyota code C0246, check the ABS actuator relay circuit for potential faults.
To diagnose and fix OBDII code C0246 in a Toyota, start by checking the transmission control module (TCM) power and ground using a multimeter.
Verify TCM communication over the Controller Area Network (CAN) network with a scan tool.
If communication issues are detected, reprogramming or reflashing the TCM 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.
This thorough inspection will help identify and address the root cause of the C0246 fault code.
