5. When the repair work is completed, return the ignition switch to the ″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of al l control units using CONSULT-III.
Precaution for WorkINFOID:0000000003775660
 When removing or disassembling each component, be ca reful not to damage or deform it. If a component
may be subject to interference, be sure to protect it with a shop cloth.
 When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the component
with a shop cloth or vinyl tape to protect it.
 Protect the removed parts with a shop cloth and keep them.
 Replace a deformed or damaged clip.
 If a part is specified as a non-reusable part, always replace it with new one.
 Be sure to tighten bolts and nuts securely to the specified torque.
 After re-installation is completed, be sure to check that each part works normally.
 Follow the steps below to clean components.
- Water soluble foul: Dip a soft cloth into lukewarm water, and wring the water out of the cloth to wipe the fouled area.
Then rub with a soft and dry cloth.
- Oily foul: Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%), and wipe
the fouled area.
Then dip a cloth into fresh water, and wring the water out of the cloth to wipe the detergent off. Then rub with
a soft and dry cloth.
 Do not use organic solvent such as thinner, benzene, alcohol, or gasoline.
 For genuine leather seats, use a genuine leather seat cleaner.

AUDIO SYSTEM
The majority of the audio troubles are the result of outside causes (bad CD, electromagnetic interference,
etc.).
Noise
The following noise results from variations in field strength, such as fading noise and multi-path noise, or
external noise from trains and other sources. It is not a malfunction.
• Fading noise: This noise occurs because of variations in the field strength in a narrow range due to moun-
tains or buildings blocking the signal.
• Multi-path noise: This noise results from the waves sent directly from the broadcast station arriving at the antenna at a different time from the waves which reflect off mountains or buildings.
The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunctioning.
Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and opera-
tion of each piece of electrical equipment, and determine the cause.
NOTE:
The source of the noise can be found easily by listening to the noise while removing the fuses of electrical
components, one by one.
Type of Noise and Possible Cause
NAVIGATION SYSTEM
Basic Operation
Vehicle Mark
Occurrence condition Possible cause
Occurs only when engine is ON. A continuous growling noise occurs. The speed of
the noise varies with changes in the engine speed. • Ignition components
The occurrence of the noise is linked with the operation of the fuel pump. • Fuel pump condenser
Noise only occurs when various
electrical components are oper-
ating. A cracking or snapping sound occurs with the op-
eration of various switches.
• Relay malfunction, audio unit malfunction
The noise occurs when various motors are operat-
ing. • Motor case ground
•Motor
The noise occurs constantly, not just under certain conditions. • Rear defogger coil malfunction
• Open circuit in printed heater
• Poor ground of antenna feeder line
A cracking or snapping sound occurs while the vehicle is being driven, especially when
it is vibrating excessively. • Ground wire of body parts
• Ground due to improper part installation
• Wiring connections or a short circuit
Symptom
Cause Remedy
No image is shown. Display brightness adjustment is set fully to DARK
side. Adjust the display brightness.
No guide sound is heard.
Audio guide volume is too low or
too high. Volume control is set to OFF, MIN or MAX. Adjust the audio guide volume.
Audio guidance is not available while the vehicle is
driving on a dark pink route.
System is not malfunctioning.
Screen is too dark.
Motion of the image is too slow. Temperature inside the vehicle is low.
Wait until the temperature inside the vehicle
reaches the proper temperature.
Small black or bright spots appear
on the screen. Symptom peculiar to a liquid crystal display (dis-
play unit). System is not malfunction.

AIR PRESSURE MONITOR
AIR PRESSURE MONITOR : Diagnosis DescriptionINFOID:0000000003776404
DESCRIPTION
During driving, the TPMS receives the signal transmitt
ed from the transmitter installed in each wheel, when
the tire pressure becomes low. The control unit (BC M) of this system has pressure judgment and trouble diag-
nosis functions.
When the TPMS detects low inflation pressure or anot her unusual symptom, the warning lamps in the combi-
nation meter comes on.
SELF DIAGNOSTIC PROCE DURE (WITH CONSULT-III)
With CONSULT-III
 Touch “SELF-DIAG RESULTS” display to show malf unction experienced since the last erasing operation.
Refer to BCS-51, "DTC Index"
.
SELF DIAGNOSTIC PROCE DURE (WITHOUT CONSULT-III)
Without CONSULT-III
To start the self-diagnostic results mode, ground terminal of the tire pressure warning check connector. The
malfunction location is indicated by the warning lamp flashing.
NOTE:
When the low tire warning lamp flashes 5 Hz and continues repeating it, the system is normal.
Test Item Operation Description
OIL PRESSURE SW OFF OFF

BCM transmits the oil pressure switch signal to the combination meter via CAN communica-
tion, which operates the oil pressure gauge in the combination meter.

Precaution for Brake SystemINFOID:0000000003772409
• Always use recommended brake fluid. Refer to MA-12, "Fluids and Lubricants".
• Do not reuse drained brake fluid.
• Be careful not to splash brake fluid on painted areas.
• To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use clean brake fluid.
• Do not use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
• Use flare nut wrench when removing and installing brake tube.
• Always check tightening torque when installing brake lines.
• Before working, turn ignition switch to OFF and disconnect con- nectors for ABS actuator and electric unit (control unit) or battery
terminals.
• Burnish the brake contact surfaces after refinishing or replacing drums or rotors, after replacing pads or linings, or if a soft pedal
occurs at very low mileage. Refer to BR-30, "
Brake Burnishing
Procedure".
WARNING:
• Clean brake pads and shoes wi th a waste cloth, then wipe
with a dust collector.

CALIPER INSPECTION
Cylinder Body
Check inside surface of cylinder for score, rust, wear, damage or foreign materials. If any of the above condi-
tions are observed, replace cylinder body.
Minor damage from rust or foreign materials may be el iminated by polishing surface with a fine emery paper.
Replace cylinder body if necessary.

Torque Member
Check for wear, cracks, and damage. If damage or def ormation is present, replace the affected part.
Piston
Check piston for score, rust, wear, damage or presence of foreign materials. Replace if any of the above con-
ditions are observed.
CAUTION:
Piston sliding surface is plated, do not polish with emery paper even if rust or foreign materials are
stuck to sliding surface.
Sliding Pins, and Sliding Pin Boots
Check sliding pin and sliding pin boot for wear, damage, and cracks. If damage or deformation is present,
replace the affected part.
CAUTION:
Trailing/upper slidi ng pin must be replaced at each service.
ASSEMBLY
1. Install bleed valve and cap.
2. Apply rubber grease to new piston seals and insert seals into
grooves on cylinder body.
CAUTION:
Do not reuse piston seals.
