- Wiring issue (e.g. open circuit, short to ground, short to power, etc.)
- ECM (engine control module) issue (i.e. internal short, open, etc.)
- Open or shorted cruise control function switch(s)
- Damaged connectors within the cruise control system
- Blown fuses, which could indicate a much more serious problem. (e.g. short, voltage spikes, control module(s) defective, etc.)
Severity of P0575 OBD II Trouble Code
This particular code is actually a mild issue that does not require immediate repair since the engine performance won't suffer which will allow the vehicle itself to be operational. Not being able to utilize the cruise control is the only main issue with this kind of code.
