Those are known for bad key pads and broken harnesses in the handle. Watch out for TVH replacement harnesses. Sometimes the wires are wrong and blow the key pads.
Touchpad itself may be bad...upon startup hold down horn button to see if options show on display...do not let go of horn button until it says e..then post the errors
I now have a manual. Following the wiring diagram, I seem to have power going to the components, and all the fuses check ok, but the keypad does not light up, even though it has power and ground connections. I did replace the controller, since that is what the seller said was supposed to be the problem, but nothing changed. I suspect that there is an issue with the keypad/handle controls but am not certain how to verify that.
If you can email me..I can walk you through the repair..[email address removed]
Does the green led light up when code is entered? Try 1258
Nothing lights up, horn doesn't work. I input 1 and the green button, which is supposed to be the basic code to start it.
What code are you putting in? do the led's on the key pad light?
