BZR_OUT

Off/On

  • Off: Keyless beeper does not sound.

  • On: Keyless beeper sounds.

  • When the simulation item BZR_OUT is turned on, a force override signal is sent to the LF control unit from the start stop unit, and the LF control unit drives (sounds) the keyless beeper.

  • With adoption of a separate excitation buzzer to the keyless beeper, buzzer does not sound normally even if the voltage is applied to the buzzer unit because there is no oscillation circuit. The integrity of the keyless beeper is determined using the simulation item BZR_OUT.

  • If the keyless buzzer does not sound even though the simulation function BZR_OUT is on, perform diagnosis using the following procedure.

    • Press the remote transmitter lock/unlock button repeatedly and measure the terminal voltage of the keyless buzzer when the button is pressed.

        • Voltage is output

      • Keyless buzzer malfunction may have occurred.

        Voltage is not output

      • Related wiring harness, or LF control unit malfunction may have occurred.
