I have problem with my door I installed alarm and everything was working fine. Now I had the doors locking on its own. I saw wire that was not well conected to white wire going to ignition. Now after fixing the conection I did not get locking, but now the lock and unlock button does not do anything and keyless only locks the car does not unlock I have to use key. The car alarm does not lock the door on unlocks them. Does anyone has wiring diagram for sc300 so I can retrace wiring? What could be wrong ? Could be bad ground ?
