Mitsubishi Montero (1998+). Manual — part 305

Except Eclipse & Montero Sport

1) Remove sun roof motor. See DRIVE MOTOR R & I under REMOVAL

& INSTALLATION. Using crank handle stored in tool pouch, place crank

handle into drive motor shaft.

2) Place spring scale on crank handle about 3.92" (100 mm)

from drive motor shaft. Ensure spring scale is at right angle to crank

handle. On Galant, connect battery source to sun roof motor connector

terminals No. 1 and 4 to rotate motor. See Fig. 4. On Montero, connect

battery source to sun roof motor connector terminals No. 1 and 3 to

rotate motor. See Fig. 5. On 3000GT, connect battery source to sun

roof motor connector terminals No. 1 and 2 to rotate motor. See Fig. 6

.

3) On Galant, spring scale should read 30-38 INCH lbs. (3.4-

4.3 N.m). On Montero and 3000GT, spring scale should read 35-43 INCH

lbs. (3.9-4.9 N.m). If clutch sliding force is not as specified, on

Galant and Montero, adjust motor adjusting nut to left or right. On

3000GT, replace sun roof motor.

COMPONENT TESTS

DRIVE MOTOR

Eclipse & Montero Sport

Remove drive motor. See DRIVE MOTOR R & I under REMOVAL &

INSTALLATION. Using 12-volt power supply, apply voltage to 2-terminal

connector. Reverse power supply leads to reverse motor direction.

Replace motor as necessary.

Galant

Remove drive motor. See DRIVE MOTOR R & I under REMOVAL &

INSTALLATION. Using 12-volt power supply, apply voltage to terminals

No. 1 (Blue wire) and No. 4 (Blue/White wire) of 6-terminal drive

motor connector. Reverse power supply leads to reverse motor

direction. Replace motor as necessary.

Montero

Remove drive motor. See DRIVE MOTOR R & I under REMOVAL &

INSTALLATION. Using 12-volt power supply, apply voltage to terminals

No. 1 (Green wire) and No. 3 (Green/Red wire and Black wire) of 4-

terminal drive motor connector. Reverse power supply leads to reverse

motor direction. Replace motor as necessary.

3000GT

Remove drive motor. See DRIVE MOTOR R & I under REMOVAL &

INSTALLATION. Using 12-volt power supply, apply voltage to terminals

No. 1 (Red/Blue wire) and No. 2 (Red/Yellow wire) of 8-terminal drive

motor connector. Reverse power supply leads to reverse motor

direction. Replace motor as necessary.

DRIVE MOTOR LIMIT SWITCH

Eclipse & Montero Sport

1) Remove sun roof ECU. Look into viewing windows while

turning rotating wheel. See Fig. 2. Turn rotating wheel until White

marks appear. When White marks appear in viewing windows at same time,

stop turning rotating wheel.

Galant

Remove limit switches from drive motor. Using ohmmeter, check

continuity of each switch. Continuity should exist between terminals

No. 3 (Blue/Red wire) and No. 5 (Black wire) for switch No. 1, and

terminals No. 5 (Black wire) and No. 6 (Blue/Black wire) for switch

No. 2. Replace switches as necessary. See Fig. 4.

Montero

Using ohmmeter, check continuity of limit switch. When

intermittent gear cam of drive motor depresses switch lever,

continuity should exist between right side terminals (No. 2 and 4) of

drive motor 4-terminal connector (connector latch upward). Replace

drive motor if switch fails test. See Fig. 5.

3000GT

Remove limit switches from drive motor. Using ohmmeter, check

continuity of each switch. Continuity should exist between terminals

No. 5 and 6 for switch "A", and terminals No. 5 and 8 for switch "B".

Replace switches as necessary. See Fig. 6.
