TEST PROCEDURES
1. Select a quiet area for testing.
2. Duplicate problem (customer complaint) as much as
possible.
3. Judge if the noise is abnormal (ie. it is important to
understand the characteristics of the vehicle and its normal
state to judge what is abnormal) - Compare with similar
vehicle if necessary.
4. Detail what and how noise occurs.
5. Find the noise source and verify its transmission by isolating
the subject part from the vehicle.
6. Repair the problem.
7. Explain and report your findings.

Before inspection and adjustment, set vehicle in the following
condition:
Engine coolant temperature: 80 90 C (176.0 194.0 F)
Lights, electric cooling fan and accessories: OFF
Transmission: Neutral ("N" or "P" position)
Steering wheel: Straightforward
1. Check whether or not the idle speed is the standard value.
Standard value: 680
50 r/min
2. Turn on the air conditioning switch and the blower speed
selection dial. Engine idling speed should be within the
standard value:
Standard value: 680
50 r/min
NOTE: The Electronic control unit determines whether the
A/C load is low or high according to the output signal from
the A/C-ECU.
NOTE: It is not necessary to make an adjustment, because
the idling speed is automatically controlled by the ENGINE
ECU. BATTERY

GENERAL DESCRIPTION
BASIC BRAKE SYSTEM35A-2
GENERAL DESCRIPTIONM1351000100440
The brake system has been designed to give greater
reliability and durability and to provide excellent brak-
ing performance.
FEATURES
.
Improved braking performance
1. An 8+9 inch tandem brake booster provides suffi-
cient braking force in sudden braking range.
2. 296mm front ventilated disc brakes provide sta-
ble braking force and improved braking feel.
3. 303mm rear ventillated disc brakes are used.
.
Improved stability
1. A 4-wheel anti-lock braking system (4ABS) pre-
vents slipping caused by the vehicle wheels lock-
ing up, in order to maintain a stable vehicle
posture and steering performance.
2. An electronic brake-force distribution (EBD)
makes it possible to maintain the maximum
amount of braking force even when the vehicle's
load is unevenly distributed. 3. Front- and rear-wheel X-type brake line layout
are used.
4. Ventilated discs brakes improve anti-fading per-
formance.
.
Improved serviceability
1. A diagnosis function for the ABS system makes
inspection easier.
2. An outer disc separated hub and rotor make
removal and installation easier.
3. The master cylinder reservoir is utilised for both
brake and clutch fluid on manual transmission
vehicles.
4. The master cylinder filter is coloured black for
improved viewing.
5. The ABS-ECU and hydraulic unit are integrated
to make them more compact and light weight.

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.
