( 1) - Examples of severe corrosion are: composite plate
separated from friction surfaces and cooling fins
cracked or missing.
( 2) - Only applies to vehicles for which OEM "machine to"
specifications exist. If OEM does not supply "machine
to" specifications, the rotor may be worn to discard
specifications.
( 3) - If OEM does not supply "machine to" specifications,
you may machine to discard specifications.
( 4) - Scoring is defined as grooves or ridges in the friction
contact surface. Some vehicle manufacturers require
machining when scoring exceeds their allowable
specifications.

COMPUTER RELEARN PROCEDURES
1998 Mitsubishi Montero
GENERAL INFORMATION
Computer Relearn Procedures
All Models
* PLEASE READ THIS FIRST *
The following general procedures are to be used if
driveability problems are encountered after power loss or battery has
been disconnected. These procedures may provide an aid in eliminating
these problems.
To reduce the possibility of complaints, after any service
which requires battery power to be disconnected, vehicle should be
road tested.
COMPUTER RELEARN PROCEDURES
Vehicles equipped with engine or transmission computers may
require a relearn procedure after vehicle battery is disconnected.
Many vehicle computers memorize and store vehicle operation patterns
for optimum driveability and performance. When vehicle battery is
disconnected, this memory is lost. The computer will use default data
until new data from each key start is stored. As computer memorizes
vehicle operation for each new key start, driveability is restored.
Vehicle computers may memorize vehicles operation patterns for 40 of
more key starts.
Customers often complain of driveability problems during
relearn stage because vehicle acts differently then before being
serviced. Depending on type and make of vehicle and how it is
equipped, the following complaints (driveability problems) may exist:
* Harsh Or Poor Shift Quality
* Rough Or Unstable Idle
* Hesitation Or Stumble
* Rich Or Lean Running
* Poor Fuel Mileage
These symptoms and complaints should disappear after a number
of drive cycles have been memorized. To reduce the possibility of
complaints, after any service which requires battery power to be
disconnected, vehicle should be road tested. If a specific relearn
procedure is not available, the following procedure may be used:
Automatic Transmission
* Set parking brake, start engine in "P" or "N" position.
Warm-up vehicle to normal operating temperature or until
cooling fan cycles.
* Allow vehicle to idle for one minute in "N" position. Select
"D" and allow engine to idle for one minute.
* Accelerate at normal throttle position (20-50%) until vehicle
shifts into top gear.
* Cruise at light to medium throttle.
* Decelerate to a stop, allowing vehicle to downshift, and use
brakes normally.
* Process may be repeated as necessary.

Electric Cooling Fan Relay (Diamante, Eclipse, Galant &
Mirage)
1) Remove radiator fan motor relay from relay box located at
right side of engine compartment. Check for continuity between relay
terminals No. 1 and 3. If continuity exists, go to next step. If
continuity does not exist, replace cooling fan relay. See Fig. 8.
2) Using a fused jumper wire, connect battery voltage to
cooling fan relay terminal No. 1. Using another jumper wire, connect
cooling fan relay terminal No. 3 to battery ground. With cooling fan
relay energized, there should be continuity between cooling fan relay
terminals No. 4 and 5. With cooling fan relay not energized, there
should be no continuity between terminals No. 4 and 5. If continuity
does not exist as specified, replace cooling fan relay. See Fig. 8.
Electric Cooling Fan Relay (Montero, Montero Sport & 3000GT)

SYSTEM TESTING
NOTE: For appropriate wiring diagram, see WIRING DIAGRAMS.
NOTE: Radiator fan on Montero and Montero Sport is mounted to a
hydraulic fan clutch which is mounted to the water pump.
Replace fan clutch if leaks are detected at case joints and
seals, fan can be rotated with very light resistance or the
bimetallic strip is damaged.
NOTE: Operation of radiator and condenser fans is controlled by
vehicle Powertrain Control Module (PCM). Based on vehicle
