If the rear door RH 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 RH (entry lock switch) → rear door electrical key oscillator RH).

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).

If the front passenger side door 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) → front passenger side door outside handle (entry lock switch) → front passenger side door electrical key oscillator).

If the driver side door 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) → driver side door outside handle (entry lock switch) → driver side door electrical key oscillator).

When the rear door RH entry lock and unlock functions do not operate, one of the following may be malfunctioning: 1) power door lock system, 2) rear door electrical key oscillator RH, or 3) certification ECU (smart key ECU assembly).

When the rear door LH entry lock and unlock functions do not operate, one of the following may be malfunctioning: 1) power door lock system, 2) rear door electrical key oscillator LH, or 3) certification ECU (smart key ECU assembly).

When the front passenger side door entry lock and unlock functions do not operate, one of the following may be malfunctioning: 1) power door lock system, 2) front passenger side door electrical key oscillator, or 3) certification ECU (smart key ECU assembly).

When the driver side door entry lock and unlock functions do not operate, one of the following may be malfunctioning: 1) power door lock system, 2) driver side door electrical key oscillator, or 3) certification ECU (smart key ECU assembly).

If the rear door RH 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) → rear door outside handle RH → rear door electrical key oscillator RH).

If the rear door LH 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) → rear door outside handle LH → rear door electrical key oscillator LH).
