ENTRY AND START SYSTEM (for Entry Function) - Driver Side Door Entry Unlock Function does not Operate


DESCRIPTION

If the driver side door entry unlock function does not operate but the entry lock function operates, the communication line between the vehicle and electrical key transmitter is normal. The part at fault may be a touch sensor circuit (certification ECU (smart key ECU assembly) → driver side door outside handle → driver side door electrical key oscillator).
