Circuit description

If only the entry lock/unlock function does not work on the driver's door, it means that a request code might not be transmitted from the driver's door, or that the front door outer handle ASSY (driver's side) (touch sensor) might be faulty. If the entry function works properly on other doors, the electrical key transmitter SUB-ASSY and the door control receiver are functioning properly. It can therefore be assumed that something is wrong with the transmission of a request code (communication between the collation ECM (smart key ECM ASSY) and the front door outer handle ASSY (driver's door) (driver's door electrical key antenna)), or that interference from external radio waves is present.
