Input Check
- Using the Mitsubishi Multi-Use Tester or voltmeter, check whether or not the input signals from each switch are being input to the Electronic Theft Alarm Control System (ETACS) control unit.
- Connect the Multi-Use Tester to the diagnosis check connector located at the right side of the junction block, or connect the voltmeter between the ETACS terminal and the ground terminal. See Fig 1

- Check if the Multi-Use Tester buzzer sounds or the needle of the voltmeter moves when each switch is operated.
- If buzzer sounds or the needle of the voltmeter moves, the input signals are being input to the ETACS unit, so that switch can be considered to be functioning normally. If not, the switch or switch input circuit is faulty. Check the switch and switch input circuit.
