Ford Fiesta

Ford Fiesta in for the radio not powering up. It had been to a ‘specialist’ that had tested radio and said it was a wiring fault.

These radios come in 3 separate pieces, the display, the audio unit and the keypad. With accurate wiring diagrams we were able to test feeds and grounds to the audio unit and also the communication lines know as Canbus, all proved good. So even though a radio expert had said it was wiring we have proved the wiring is OK.

We didn’t suspect the display as it would still have sound. The audio unit was checked for current draw and a thermal camera used to see if it was getting warm. This isn’t 100% test but an indication it’s working. There is no way of testing keypad, only substitute for another which we had available.

This proved to be the problem as it came on and worked perfectly.

Another job successfully completed without any guess work or unnecessary parts fitted.
