Input Check (ETACS Equipped Models Only)

Using the multi-use tester, check whether or not the input signals from each switch are being input to the electronic control unit.

1. Connect the multi-use tester to the diagnosis connector (located at the right side of the junction block).See Fig 1 .
2. With the ignition switch at the ACC position, set the multi-use tester to the special test setting.
3. Check to be sure that the buzzer of the multi-use tester sounds one time when each switch noted below is operated. If the buzzer sounds, the input signals are being input to the electronic control unit, so that switch can be considered to be functioning normally. If the buzzer does not sound, check for a malfunction of that switch or for damaged or disconnected wiring (ignition switch or front door switch).
