That is the PCB not the ECU. You can't repair it. But if it all works with the lights on I would wire the lights on permanently. There are 2 micro relays for power on the board and on mine the one for just the ignition on was failing but the one with the lights worked.

The realys are if you have a UK car in the top right corner under the dash.
