Mitsubishi Montero (1991+). Manual — part 63

ACTUATOR TESTS

Resistance Test (1991)

Disconnect actuator connector. Resistance between terminals

No. 1 and 2 should be 20 ohms. See Figs. 17-21. If resistance is not

correct, replace actuator assembly.

Operational Test (1991)

1) With connector disconnected, connect battery voltage to

terminal No. 1. See Figs. 17-21. Ground terminal No. 2. Connect

ammeter between positive side of battery and terminal No. 1 of

actuator connector.

2) Solenoid should make a click sound. Ammeter should read .

5-.7 amps. Connect positive side of battery to terminal No. 4 and

ground terminal No. 3. Actuator should pull in and stop.

3) While actuator is moving in, ammeter should read less than

.5 amps. When actuator travel reaches midpoint, disconnect terminal

No. 1 from positive side of battery. Actuator should return to

original position. If actuator does not test correctly, replace

actuator.

4) Reverse connections of terminals No. 4 and 3 in step 2).

Connect battery voltage to terminal No. 3 and ground terminal No. 4.

Actuator should move out then stop. While actuator is moving, ammeter

should read less than .5 amps.

1992

Remove actuator. Apply vacuum to actuator. Actuator linkage

holder should move more than 1.38" (35 mm). Actuator diaphragm should

hold vacuum. Replace actuator if actuator does not test correctly.

VEHICLE SPEED SENSOR TEST

1) Remove instrument cluster. See INSTRUMENT CLUSTER under

REMOVAL & INSTALLATION. Check continuity between vehicle speed sensor

terminals at instrument cluster. See Fig. 30 or 31.

2) Ensure continuity pulses on and off 4 times per revolution

of speedometer shaft connection. If continuity is not as specified,

replace vehicle speed sensor.
