Maverick control unit cable fault

I'm having issues with my 2004 Ford Maverick diesel. I'm getting sporadic driving mode errors and the error lamps light up sometimes. The audio and navigation systems are failing, and some control units are temporarily shutting down with error codes. Could this be a faulty control module?

That sounds like a headache. Intermittent issues are tricky. When the errors pop up, are they always the same, or do they seem random? Have you tried reading the error codes yourself with an OBD-II scanner, or are you relying on the dashboard warnings?

The errors seem random. I've used an OBD-II scanner, and the error codes point to control module issues, but I'm unsure of the next steps. Could a defective cable connection to the BUS system cause these widespread problems?

A bad connection to the BUS system could cause weirdness like that. It's like a central nervous system for the car's electronics. If it's flaky, modules can drop offline or give false readings. It sounds like you've gone as far as you can without specialized tools. I'd take it to a workshop. They have better diagnostic equipment and can pinpoint the exact wiring issue.

I took the Ford Maverick to a local workshop. The issue was a defective cable connection to the BUS system of a control unit. The repair cost 155€. Thanks for your help diagnosing the problem.
