Code C1122 Description

The C1122 code refers to a fault in the Front Right Input ABS Solenoid, which is a crucial component of the anti-lock braking system (ABS) in a vehicle. The ABS solenoid is responsible for regulating hydraulic pressure to the individual wheel brakes, helping to prevent skidding and maintain control during emergency braking situations. When this solenoid malfunctions, it can impact the vehicle's ability to effectively modulate brake pressure, potentially compromising the overall safety and performance of the braking system.

Tech Notes for C1122

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 Input ABS solenoid is open or shorted, or control line is open or shorted to power supply or ground.
