Code C1123 Description

The C1123 diagnostic trouble code (DTC) refers to a fault in the Front Right Out ABS Solenoid circuit. ABS (Anti-lock Braking System) solenoids are responsible for controlling the brake pressure to prevent wheel lock-up during braking. When the ABS system detects a malfunction in the Front Right Out solenoid circuit, it may disable the ABS system, leading to potential safety concerns. This issue can affect the vehicle's braking performance, especially during emergency braking situations. It is important to address this code promptly to ensure the ABS system functions correctly.

Tech Notes for C1123

The ABS has an electronic control unit to control major functions. The control unit accepts input signals from sensors and controls operation of the actuator. It is also important to check for conventional problems such as air leaks in the booster or lines, lack of brake fluid, or other problems with the brake system.
It is much more difficult to diagnose a problem that occurs intermittently rather than continuously. Most intermittent problems are caused by poor electrical connections or faulty wiring. In this case, careful checking of suspicious circuits may help prevent the replacement of good parts.

When is the Code Detected?

Circuit of front Right Output ABS solenoid is open or shorted, or control line is open or shorted to power supply or ground.
