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.
Manual Transmission
Page 223 of 1333
* Place transmission in Neutral position.
* Ensure emergency brake has been set and all accessories
are turned off.
* Start engine and bring to normal operating temperature.
* Allow vehicle to idle in Neutral for one minute.
* Initial relearn is complete: process will be completed during
normal driving.
Some manufacturers identify a specific relearn procedure
which will help establish suitable driveability during relearn stage.
These procedures are especially important if vehicle is equipped with
and electronically controlled automatic transmission or transaxle.
Always complete procedure before returning vehicle to customer.

CRUISE CONTROL SWITCH FUNCTION TEST
NOTE: If vehicle speed decreases approximately 9 MPH below set
speed, set speed will be cancelled.
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.
NOTE: Speed will not set beyond system limit of 90 MPH.
2) With cruise control switch in ON position, drive vehicle
between 25 and 90 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 from ON to OFF position. Vehicle speed should return to
previous setting before cancellation. Set speed should cancel when any
of the following occurs:
* Brake pedal is pressed.
* Clutch pedal is pressed.
* Transmission is shifted to Neutral or Park.
* Cruise control main switch is turned off.
* Ignition switch is turned off.
SELF-DIAGNOSTICS
1) Self-diagnostics should be performed when cruise control
cancels without the driver using normal cancel modes. Diagnosis
connector is located on right side of fuse box. Use analog voltmeter
or Multi-Use Tester (MB991341) for code retrieval.
2) Use multi-use tester according to operating instructions
provided with tester. Connect leads of analog voltmeter between cruise
control terminal and ground terminal of self-diagnostic connector. See
Fig. 6 . Read voltmeter needle sweeps to determine trouble code.
NOTE: On 1991 models, codes No. 13, 14, 15, 16 and 17 will be
displayed whether malfunction is present or not.
3) Once trouble codes have been displayed, see SELF-
DIAGNOSTIC CODE CHART to determine appropriate CIRCUIT TEST. See
Fig. 7 or 8.
4) To clear trouble codes, either disconnect battery cable or
turn ignition on. Turn main cruise control switch and set switch to ON
position. Within one second turn resume switch to ON position.
5) Hold stoplight switch and cruise control switch in ON
position for more than 5 seconds. Verify codes are cleared.

TESTING & INSPECTION
AXLE SHAFT END PLAY
Using dial indicator, check axle shaft end play. End play
must be .0020-.0079" (.05-.20 mm). If end play is not within
specification, change shims to obtain correct end play. See AXLE
SHAFTS under REMOVAL & INSTALLATION.
AXLE TOTAL BACKLASH
1) Raise and support rear axle. Place transmission in
Neutral. Apply parking brake. Rotate drive shaft clockwise. Place
reference marks on pinion dust cover and differential housing.
2) Rotate drive shaft counterclockwise and measure distance
between reference marks. Differential must be removed and backlash
adjusted if distance exceeds 0.2" (5.0 mm).
LIMITED SLIP DIFFERENTIAL PRELOAD
1) Place transmission in Neutral. Block front wheels. Raise
one rear wheel free of ground and remove wheel. Use Axle Puller
Adapter (MB990241) for Montero and Pickup models. Install adapter on
wheel studs. Release parking brake.
2) Using torque wrench, measure starting torque on Pickup
models while rotating wheel in forward direction. On Montero models,
measure rotating torque. This measurement is read once axle is
turning. Differential must be repaired if torque is less than
specification. See TESTING SPECIFICATIONS table.

INTRODUCTION TO MOTORIST ASSURANCE PROGRAM (MAP)
OVERVIEW OF MOTORIST ASSURANCE PROGRAM
The Motorist Assurance Program is the consumer outreach
effort of the Automotive Maintenance and Repair Association, Inc.
(AMRA). Participation in the Motorist Assurance Program is drawn from
retailers, suppliers, independent repair facilities, vehicle
manufacturers and industry associations.
Our organization's mission is to strengthen the relationship
between the consumer and the auto repair industry. We produce
materials that give motorists the information and encouragement to
take greater responsibility for their vehicles-through proper,
manufacturer-recommended, maintenance. We encourage participating
service and repair shops (including franchisees and dealers) to adopt
(1) a Pledge of Assurance to their Customers and (2) the Motorist
Assurance Program Standards of Service. All participating service
providers have agreed to subscribe to this Pledge and to adhere to the
promulgated Standards of Service demonstrating to their customers that
they are serious about customer satisfaction.
These Standards of Service require that an inspection of the
vehicle's (problem) system be made and the results communicated to the\
customer according to industry standards. Given that the industry did
not have such standards, the Motorist Assurance Program successfully
promulgated industry inspection communication standards in 1994-95 for
the following systems: Exhaust, Brakes, ABS, Steering and Suspension,
Engine Maintenance and Performance, HVAC, and Electrical Systems.
Further, revisions to all of these inspection were recently published.
Further, revisions to all of these inspection communication standards
are continually republished. In addition to these, standards for Drive
Train and Transmissions have recently been promulgated. Participating
shops utilize these Uniform Inspection & Communication Standards as
part of the inspection process and for communicating their findings to
their customers.
The Motorist Assurance Program continues to work
cooperatively and proactively with government agencies and consumer
groups toward solutions that both benefit the customer and are
mutually acceptable to both regulators and industry. We maintain the
belief that industry must retain control over how we conduct our
business, and we must be viewed as part of the solution and not part
of the problem. Meetings with state and other government officials
(and their representatives), concerned with auto repair and/or
consumer protection, are conducted. Feedback from these sessions is
brought back to the association, and the program adjusted as needed.
To assure auto repair customers recourse if they were not
satisfied with a repair transaction, the Motorist Assurance Program
offers mediation and arbitration through MAP/BBB-CARE and other non-
profit organizations. MAP conducted pilot programs in twelve states
before announcing the program nationally in October, 1998. During the
pilots, participating repair shops demonstrated their adherence to the
Pledge and Standards and agreed to follow the UICS in communicating
the results of their inspection to their customers. To put some
"teeth" in the program, an accreditation requirement for shops was
initiated. The requirements are stringent, and a self-policing method

NOTE: Whenever transmission or drivetrain service is performed
that affects the suspension alignment, for example,
removing the engine cradle, it is required that the
alignment be checked and corrected if necessary.
