ENTRY AND START SYSTEM (for Entry Function) - Rear Door LH Entry Lock Function does not Operate

DESCRIPTION

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

HINT:

For vehicles with entry function for rear doors.
