Details of the c1ab4 OBD Code
Code c1ab4 relates to a fault in the steering angle sensor module.
OBD code C1AB4 means that there is a fault with the left rear speed sensor circuit.
This code is triggered by the Antilock Braking System (ABS) module when it detects an issue with the signal coming from the left rear wheel speed sensor.
The ABS module uses this sensor to monitor the speed of the left rear wheel to help prevent wheel lockup during braking.
If the sensor or its circuit has a fault, it can affect the proper operation of the ABS system.
Mechanic’s Tech Notes
This fault code c1ab4 indicates a steering angle sensor internal fault.
OBDII code C1AB4 relates to a transmission control module (TCM) communication error.
To diagnose, check TCM power and ground using a multimeter.
Verify TCM response over the Controller Area Network (CAN) network with a scan tool.
Visually inspect wiring harness and connectors for damage, focusing on broken, bent, or corroded pins.
Reflash the TCM if necessary.
This process helps ensure proper power supply, ground connections, and communication integrity, aiding in resolving the C1AB4 fault code.
