Toyota 8FGCU25:
Seat switch

Hello,

I have a Toyota 8FGCU25 with the seat switch light staying on and no functions. Even bypassed it still stays on. I trace the wires back to the fuse relay under the controller (close to the battery) and get a good tone all the way through the circuit. I'm thinking it's the controller but any advice would be helpful. Can it be a broken wire up in the dash? Also the history on the unit is the driver left the lights on overnight, my customer jump started it with a suburban the next day, got it to start but seat switch light staying on now. Please help, I'm on day 4 of this and customer is extremely busy.

Check ecu fuses. One or all are blown. Replace them even though. Had many somewhat blow but still could emit a ohm signal as good and not carry enough voltage through to signal ecu to let it function.
