When using the scan tool (MUT) or voltmeter‘d
Using the scan tool or voltmeter, check whether or not the
input signals from each switch are being input to the ETACS
unit.
54-56CHASSIS ELECTRICAL - Lighting System
(1) Connect the scan tool to the data link connector located
at the right side of the junction block or connect the voltme-
ter between the ETACS terminal and the ground terminal.
(2) Check if the buzzer of the scan tool sounds or the needle
of the voltmeter moves when each switch is operated.
If the buzzer sounds or the needle moves, the input signalsare 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 the
switch input circuit.

connecting the scan tool to a vehicle up to 1993 models,
use the adapter harness supplied together.‘dCaution
Turn off the ignition switch beforehand whenever the
scan tool is connected or disconnected.
(2) If the scan tool makes a peep sound when each switchis operated (turned ON/OFF), the input signal to ECU
is normally sent from the switch circuit system.

When using the voltmeter
(1)Connect a voltmeter to the ETACS terminal and the ground
terminal of the data link connector using the special tool.
(2) If the voltmeter pointer deflects once when each switchis operated (turned ON/OFF), the input signal to ECU
is normally sent from the switch circuit system.
