Scan Tool Method (3000GT)
Turn ignition off. Connect scan tool to DLC. Follow scan tool
manufacturer's instructions. Turn ignition on. Perform ON/OFF
operation of each door lock or power window switch. If scan tool
buzzer sounds once, ECU input signal to corresponding switch circuit
is normal.
Voltmeter Method (3000GT)
Using Diagnostic Trouble Code Check Harness (MB991529),
connect harness to DLC terminals No. 4 and 5. Connect voltmeter to
harness. Turn ignition on. Perform ON/OFF operation of each door lock
or power window switch. If voltmeter pointer moves once, ECU input
signal from corresponding switch circuit is normal.
COMPONENT TESTS
* PLEASE READ THIS FIRST *
NOTE: If after all testing procedures are completed, system is not
functioning properly, substitute with a known-good ETACS-ECU
and retest.

wire) on Montero or terminal No. 1 (Blue/Red wire) on 3000GT. See
WIRING DIAGRAMS . Actuator should move to UNLOCK position when terminal
No. 1 (White/Black wire) on Montero or terminal No. 3 (Blue/Black
wire) on 3000GT is connected to ground.
2) With actuator set in UNLOCK position, connect positive
lead of 12-volt power source to actuator terminal No. 1 (White/Black
wire) on Montero or terminal No. 3 (Blue/Black wire) on 3000GT. See
WIRING DIAGRAMS . Actuator should move to LOCK position when terminal
No. 3 (Blue/Red wire) on Montero or terminal No. 1 (Blue/Red wire) o\
n
3000GT is connected to ground.
3) On 3000GT, check for continuity between actuator terminals
No. 2 (Brown wire) and No. 4 (Black wire). See WIRING DIAGRAMS.
