As far as I know, there is no schematic available for the BECM. As the outputs are controlled by Mosfets, it's just down to manually sorting the internal circuitry out. I have fitted new Mosfets in the past with success but without any schematics. All the Wiring diagrams on RAVE will show is the pin outs etc. to the BECM and the internal circuitry is "Hidden" to prevent people like us saving money. Diagnostic software such as Test Book or Rovacomlite "Direct Access" module will not give the logic details, only allowing programming of parameters and identifying faults.

Forgot to add that I have the Rovacomlite system and have been using it for about 5 years.

Check the power from the pin outs at the BECM then work your way back to the switch and to the motor plug. If it works when powered externally then either there is no output from the BECM or you have a switch/wiring fault.
