What is the P0576 fault code? What does it all mean?
A P0576 code is an indication of an electrical fault within the cruise control input circuit. If there is a problem in the cruise control system, the PCM will test the entire cruise system to locate the source. The code P0576 is set if the PCM detects a voltage signal coming from the cruise controller input circuit that is lower than the minimum level as specified by the manufacturer.
The P0576 fault code affects vehicles from many manufacturers, including: Mazda, Nissan Land Rover and Mercedes-Benz.

These are the most common reasons that P0576 is triggered
- – Cruise control control knobs can cause short or open circuit problems from spilled liquids
- – A defective cruise control switch
- – Defective cruise control button on/off
- – Electrical problems such as corroded connectors or broken wires.
- Broken tabs, pins worn, or swollen connector bodies
- – Dirty or grit that makes it impossible for the adjustment buttons to work
- – Damaged components due to overheating
- – Defective cruise control module

- – Cruise control buttons not working intermittently or infrequently
- – The cruise control light on the instrument cluster does not turn on or off.
- – Cruise control not set at the desired speed
- – The system’s speed can change even if it is running.

How Serious Is the P0576 Fault Code
P0576 is a moderately-classified fault code that doesn’t require immediate repair. The vehicle will continue to operate as normal, with no engine performance problems or security breaches. You will only experience a problem with the cruise control system. If the fault is caused due to shorted wires, fuses can blow. If the code is not followed, it can lead to serious electrical problems.
