The OBD II trouble codes indicate the difficult things about a car. A vehicle has many functions, including hydraulic braking systems, speed wheels, steering, signal lights, front lights, backlights, braking lights, etc. The speed wheels are related to the engine and increase the vehicle’s speed. But when they lose their balance, they become unable to provide a comfortable drive. So, the mismatching of the speed wheels can cause considerable problems in your driving.

What does the C1222 code mean?
The C1222 is the trouble code indicating the speed wheel mismatching problem. When there is no suitable connection between the ABS module and the speed wheels, it causes the C1222 trouble. The sensor ring has a magnetic field. The wheel speed sensor can detect it, and thus it can pass an active sensor. The ABS module plays a vital role in it. If there is any system problem, the module detects it to solve it. It observes the rotational speeds of every wheel. It distinguishes the wheel lock, brake pressure, and right brake caliper.
The ABS module triggers the hydraulic control unit. Thus it opens and closes the appropriate solenoid valves. It is risky for the braking system to brake the wheels when the wheels are at an over speed. So, the control unit helps to trigger the brake after the wheels return to the normal speed. But, the wheels lose their balance, and the braking system can be affected. Thus you can see the C1222 code on your OBD II scanner.
