1998 MITSUBISHI MONTERO Service Manual

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 driv\
e
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.
2) Close sun roof fully. Install timed sun roof control unit.
Ensure wiring connector is properly inserted into control unit. Insert
a flat-blade screwdriver, place on tab and press to right, being
careful not to pinch wiring. See Fig. 3.

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.
