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.

DESCRIPTION & OPERATION
WARNING: Deactivate air bag system before performing any service
operation. See AIR BAG RESTRAINT SYSTEMS article. Do not
apply electrical power to any component on steering column
without first deactivating air bag system. Air bag may
deploy.
Cruise control system is electronically and vacuum
controlled. System components include a control unit, actuator, vacuum
pump, cruise control switch, clutch pedal position switch (M/T),
cruise indicator light, diode, Park/Neutral (P/N) switch (A/T),
stoplight switch, vehicle speed sensor and A/T control unit (if
equipped).
System has self-diagnostic capability. When self-diagnostic
mode is activated, each switch and sensor is checked for defects. When
cruise control system has been canceled without using a normal cancel
method, a trouble code will be set and stored in control unit. Trouble
codes can be retrieved to help determine which circuit is
malfunctioning.

* PLEASE READ THIS FIRST *
NOTE: For further trouble shooting information, see INPUT
INSPECTION CHART. See Fig. 3. See
INSPECTION CHART FOR TROUBLE SYMPTOMS table under SYMPTOM
TESTS.
PRELIMINARY CHECKS
Inspect vacuum pump, linkage assembly, actuator, cables and
vacuum hoses. Ensure linkage and cables move smoothly. Ensure cables
do not have excessive slack or tension.
CRUISE CONTROL SWITCH FUNCTION TEST
NOTE: If vehicle speed decreases about 9 MPH less than the set
speed, set speed will be canceled. Speed will not set beyond
system limit of 124 MPH.
1) Cruise control switch is part of multifunction switch
mounted on steering column. To operate cruise control system, turn
ignition on. Turn cruise control switch to ON position. Ensure switch
indicator light comes on.
2) With cruise control switch in ON position, drive vehicle
at least 25 MPH. Press and release SET button. Vehicle speed should
stay at set speed. Instrument cluster cruise indicator light should
come on. To increase set speed, turn control switch to RESUME position
and hold until new set speed is reached.
3) To lower set speed, press SET button and hold until new
set speed is reached. To return to set speed after cancellation, move
resume switch to ON position. Vehicle speed should return to previous
setting before cancellation. Set speed should cancel when any of the
following occurs:
* Brake pedal is depressed.
* Cruise control main switch is turned to OFF position.
* Ignition switch is turned to OFF position.
* Transmission is shifted to Neutral.
SYSTEM CANCELS OR WILL NOT RESET AFTER CANCELLATION
1) Check for trouble codes. See RETRIEVING CODES under SELF-
DIAGNOSTIC SYSTEM. If no trouble codes are stored, ensure cruise
control can be set.
2) If cruise control can be set, system may have canceled due
to driving on steep hills, or a loose wiring connection. If cruise
control still cannot be set, perform SYSTEM INPUT TESTS under SYMPTOMS
TESTS.
3) If SYSTEM INPUT TESTS check okay, check vacuum pump
circuit. See CODE 11 under DIAGNOSTIC TESTS. If SYSTEM INPUT TESTS do
not check okay, see INPUT INSPECTION CHART. See Fig. 3.
SYMPTOM TESTS
SYSTEM INPUT TESTS
1) System input tests should be performed if no trouble codes
are stored when performing RETRIEVING CODES under SELF-DIAGNOSTIC
SYSTEM. System input tests cycle each cruise control switch and
sensor.
2) Use scan tool for system input check according to
operating instructions provided with scan tool. Connect leads of
analog voltmeter between cruise control terminal and ground terminal
of data link connector. See Fig. 35.
3) Turn ignition on. To display results of input check, move
cruise control SET switch to ON position. Then turn MAIN switch to ON
position. Within one second, activate RESUME switch. Codes will
display if circuit tested is okay. See Fig. 3.
