MAINTENANCE, REPAIR AND
SERVICING EXPLANATIONS
This manual provides explanations, etc. concerning
procedures for the inspection, maintenance, repair
and servicing of the subject model. Unless otherwise
specified, each service procedure covers all models.
Procedures covering specific models are identified
by the model codes, or similar designation (engine
type, transaxle type, etc). A description of these des-
ignations is covered in this manual under "VEHICLE
IDENTIFICATION."
.
ON-VEHICLE SERVICE
The "ON-VEHICLE SERVICE" section has proce-
dures for performing inspections and adjustments of
particularly important components. These proce-
dures are done with regard to maintenance and ser-
vicing, but other inspections (looseness, play,
cracking, damage, etc.) must also be performed.
.
SERVICE PROCEDURES
The service steps are arranged in numerical order.
Attention to be paid in performing vehicle service are
described in detail in SERVICE POINTS.
DEFINITION OF TERMS
.
STANDARD VALUE
Indicates the value used as the standard for judging
whether or not a part or adjustment is correct.
.
LIMIT
Shows the maximum or minimum value for judging
whether or not a part or adjustment is acceptable.
.
REFERENCE VALUE
Indicates the adjustment value prior to starting the
work (presented in order to facilitate assembly and
adjustment procedures, and so they can be com-
pleted in a shorter time).
.
DANGER, WARNING, AND CAUTION
DANGER, WARNING, and CAUTION call special
attention to a necessary action or to an action that
must be avoided. The differences among DANGER,
WARNING, and CAUTION are as follows:
If a DANGER is not followed, the result is severe
bodily harm or even death.
If a WARNING is not followed, the result could be
bodily injury.
If a CAUTION is not followed, the result could be
damage to the vehicle, vehicle components or
service equipment.
TIGHTENING TORQUE INDICATION
The tightening torque indicates a median and its tol-
erance by a unit of N
m (in-lb.) or Nm (ft.-lb.). For
fasteners with no assigned torque value, refer to
P.00-32.
SPECIAL TOOL NOTE
Only MMC special tool part numbers are called out in
the repair sections of this manual. Please refer to the
special tool cross-reference chart located at the
beginning of each group, for the special tool number
that is available in your market.

TROUBLESHOOTING GUIDELINES
GENERAL00-6
TROUBLESHOOTING GUIDELINESM1001008800340
VERIFY THE COMPLAINT
Make sure the customer's complaint and the ser-
vice writer's work order description are under-
stood before starting work.
Make sure you understand the correct operation
of the system. Read the service manual descrip-
tion to verify normal system operation.
Operate the system to see the symptoms. Look
for other symptoms that were not reported by the
customer, or on the work order, that may be
related to the problem.
DETERMINE POSSIBLE CAUSES
Compare the confirmed symptoms to the diagnostic
symptom indexes to find the right diagnosis proce-
dure.
If the confirmed symptoms cannot be found on any
symptom index, determine other possible causes.
Analyze the system diagrams and list all possible
causes for the problem symptoms.
Rank all these possible causes in order of proba-
bility, based on how much of the system they
cover, how likely they are to be the cause, and
how easy they will be to check. Be sure to take
experience into account. Consider the causes of
similar problems seen in the past. The list of
causes should be ranked in order from general to
specific, from most-likely to least-likely, and from
easy-to-check to hard-to-check.
FIND THE PROBLEM
After the symptoms have been confirmed, and prob-
able causes have been identified, the next step is to
make step-by-step checks of the suspected system
components, junctions, and links in logical order.
Use the diagnostic procedures in the service manual
whenever possible. Follow these procedures care-
fully to avoid missing an important step in the diagno-
sis sequence. It might be the skipped step that leads
to the solution of the problem.
If the service manual doesn't have step-by-step pro-
cedures to help diagnose the problem, make a series
of checks based on the ranked list of probable
causes. Troubleshooting checks should be made in
the order that the list of causes was ranked:
general to specific
most-likely to least-likely
easy-to-check to hard-to-check
REPAIR THE PROBLEM
When the step-by-step troubleshooting checks find a
fault, perform the proper repairs. Make sure to fix the
root cause of the problem, not just the symptom. Just
fixing the symptom, without fixing the root cause, will
cause the symptom to eventually return.
VERIFY THE REPAIR
After repairs are made, recheck the operation of the
system to confirm that the problem is eliminated. Be
sure to check the system thoroughly. Sometimes
new problems are revealed after repairs have been
made.

1. Check for holes and exhaust gas leaks due to damage,
corrosion, etc.
2. Check the joints and connections for looseness and exhaust
gas leaks.
3. Check the rubber hangers and brackets for damage.
9. ENGINE OIL (CHANGE)M1001002600360
Use the specified oil. (Refer to P.00-35.)
Use care as oil could be hot.
1. After warming up the engine, remove the oil filler cap.
2. Remove the drain plug to allow the engine oil to drain.
3. Install a new drain plug gasket so that it faces in the
direction shown in the illustration, and then tighten the drain
plug to the specified torque.
Tightening torque: 39
5 Nm (29 3 ft-lb)
4. Pour new engine oil in through the oil filler hole.
Specified Engine Oil:
To ta l q u a n t i t y :
<3.8L Engine> 4.6 Litres
5. Install the engine oil filler cap.
6. Start the engine and run it at idle for a few minutes.
7. Pull out the oil dipstick slowly and check that the oil level is
within the marks on the oil dipstick.
8. Check that the oil is not excessively dirty, that there is no
coolant or petrol mixed in, and that it has sufficient viscosity.
10. ENGINE OIL FILTER (REPLACE)M1001002700345
The quality of replacement filters varies considerably. Only high
quality filters should be used to assure most efficient service.
Genuine oil filters require that the filter is capable of withstand-
ing a pressure of 1,800 kPa (261 psi) are high quality filters.

TRACTION CONTROL SYSTEM (TCL) DIAGNOSIS
INTRODUCTION TO TRACTION CONTROL SYSTEM (TCL) DIAGNOSISM1136004600026
TCL Diagnostic Trouble Code Detection
Conditions
TCL diagnostic trouble codes (TCL DTCs) are set
under different conditions, depending on the mal-
function detected. Most TCL DTCs will only be set
during vehicle operation. Some TCL DTCs will also
be set during the TCL self-check immediately after
the engine is started. When you check if an TCL DTC will be displayed again after the DTC has been
erased, you should recreate the TCL DTC set condi-
tions. Depending on the detection timing and set
conditions for the specific TCL DTC, you must either
drive the vehicle or turn the engine off and restart it.
To set the proper conditions for that DTC again, refer
to "TCL DTC SET CONDITIONS" for each TCL DTC
that you are trying to reset.
TROUBLESHOOTING STRATEGYM1136003100062
Use these steps to plan your diagnostic strategy. If
you follow them carefully, you will check most of the
possible causes of a TCL problem.
1. Gather information from the customer.
2. Verify that the condition described by the
customer exists.
3. Check the vehicle for any TCL DTC. (Refer to
P.13C-3, Diagnosis Function
How to Read and
Erase Diagnostic Trouble Codes).
4. If you can verify the condition but no TCL DTCs
are set, and the malfunction may be intermittent.
(Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points
How
to Cope with Intermittent Malfunctions P.00-14).
5. If you can verify the condition but there is no TCL
DTCs, or the system cannot communicate with
diagnostic tool MB991958 (MUT-III sub
assembly), and find the fault. (Refer to P.13C-23,
Symptom Chart).6. If there is a TCL DTC, record the number of the
code, then erase the code from vehicle memory
using the diagnostic tool MB991958 (MUT-III sub
assembly). (Refer to P.13C-3, Diagnosis Function
How to Read and Erase Diagnostic Trouble
Codes).
7. Re-create the TCL DTC set conditions to see if
the same TCL DTC will set again. (Refer to
P.13C-3, Diagnosis Function
How to Read and
Erase Diagnostic Trouble Codes).
If the same TCL DTC sets again, perform the
diagnostic procedures for the set code. (Refer to
P.13C-8, Diagnostic Trouble Code Chart).
NOTE: If the ABS-8 ECU or the active wheel
speed sensor are disconnected, or if the wir-
ing is an open/ short circuit, the ABS 8 ECU
will shut off power supply to the respective
wheel speed sensor. All other wheel speed
sensors will operate normally. To restore the
power supply, the ignition switch must be
turned to the "OFF" position then to the "ON"
position again.
