Code C1190 Description

The C1190 code indicates a problem with the rear input ABS solenoid in the vehicle's anti-lock braking system (ABS). The ABS solenoid is responsible for regulating the brake pressure in the rear wheels to prevent them from locking up during sudden braking or slippery road conditions. When this solenoid malfunctions, it can affect the vehicle's ability to maintain stability and control during braking, potentially leading to longer stopping distances and increased risk of skidding.

Tech Notes for C1190

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?

When the control unit detects a malfunction in the rear inlet solenoid circuit.
