Code C1230 Description

The C1230 code indicates a problem with the rear anti-lock brake sensor in the vehicle. The anti-lock brake system (ABS) is a safety feature that prevents the wheels from locking up during braking, helping the driver maintain control of the vehicle. The sensor is responsible for measuring the rotational speed of the rear wheels and sending this information to the ABS control module. When the sensor detects a discrepancy in wheel speed, it can trigger the C1230 code.
