Hi,

Working on a TCM FB25-7. It reverse alarm and reverse buzzer is always on and the left side indicator are as well even on the switch off position.

any idea what could be the fault. I think its the CPU board faulty at rear panel..? Does CPU Board control all the lighting circuit or the controller fitted in the right side box where integral charger fits?

Thanks for help. if possible please send wiring diagram. Thanks
