DISASSEMBLY
1. Remove pads from cylinder body.
2. Remove sliding sleeve and boot from cylinder body.
3. Place a wooden block as shown, and blow air into union bolt
hole to remove piston and piston boot.
CAUTION:
Do not get your fingers caught in piston.
4. Using a suitable tool, remove piston seal from cylinder body as
shown.
CAUTION:
Be careful not to damage cylinder body inner wall.
CALIPER INSPECTION
Cylinder Body
CAUTION:
• Use new brake fluid to clean. Do not use mineral oils such as gasoline or kerosene. Refer to MA-10
.
• Check inside surface of cylinder body for score, rust wear, damage or foreign materials. If any of the
above conditions are observed, replace cylinder body.
• Minor damage from rust or foreign materials may be eliminated by polishing surface with a fine
emery paper. Replace cylinder body if necessary.
Torque Member
Check for wear, cracks, and damage. If damage or deformation is present, replace the affected part.
Piston
CAUTION:
• Piston sliding surface is plated, do not polish with emery paper even if rust of foreign materials are
stuck to sliding surface.
• Check piston for score, rust, wear, damage or presence of foreign materials. Replace if any of the
above conditions are observed.

COMBINATION METERS
Self-Diagnosis Mode of Combination Meter
INFOID:0000000003533486
SELF-DIAGNOSIS FUNCTION
The following items can be checked during Combination Meter Self-Diagnosis Mode.
• Gauge sweep and present gauge values.
• Illuminates all odometer, fuel, and engine temperature segments.
• Illuminates all micro controlled lamps/LE D's regardless of switch configuration.
• Displays estimated present battery voltage.
• Displays seat belt buckle switch LH status.
HOW TO INITIATE COMBINATION METER SELF- DIAGNOSIS MODE
NOTE:
Once entered, Combination Meter Self-Diagnosis Mode will function with the ignition switch in ON or START.
Combination Meter Self-Diagnosis Mode will exit upon turning the ignition switch to OFF or ACC.
To initiate Combination Meter Self-Diagnosis Mode, refer to the following procedure.
1. Turn the ignition switch ON, while holding the odom eter/trip meter switch for 5 - 8 seconds. When the
diagnosis function is activated the odometer/trip meter will display tESt.
NOTE:
Check combination meter power supply and ground ci rcuit when self-diagnosis mode of combination
meter does not start. Refer to DI-16, "
Power Supply and Ground Circuit Inspection". Replace combination
meter if normal. Refer to IP-10, "
Removal and Installation".
COMBINATION METER SELF-DIAGNOSIS MODE FUNCTIONS
To interpret Combination Meter Self-Diagnosis Mode functions, refer to the following table.

General PrecautionINFOID:0000000003531471
• Do not operate the engine for an extended period of time without
proper exhaust ventilation.
Keep the work area well ventilated and free of any flammable
materials. Special care should be taken when handling any flam-
mable or poisonous materials, such as gasoline, refrigerant gas,
etc. When working in a pit or other enclosed area, be sure to prop-
erly ventilate the area before working with hazardous materials.
Do not smoke while working on the vehicle.
• Before jacking up the vehicle, apply wheel chocks or other tire
blocks to the wheels to prevent the vehicle from moving. After jack-
ing up the vehicle, support the vehicle weight with safety stands at
the points designated for proper lifting before working on the vehi-
cle.
These operations should be done on a level surface.
• When removing a heavy component such as the engine or tran-
saxle/transmission, be careful not to lose your balance and drop
them. Also, do not allow them to strike adjacent parts, especially
the brake tubes and master cylinder.
• Before starting repairs which do not require battery power:
Turn off ignition switch.
Disconnect the negative battery terminal.
• If the battery terminals are disconnected, recorded memory of
radio and each control unit is erased.
• Battery posts, terminals and related accessories contain lead and
lead compounds. Wash hands after handling.
• To prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.
• Dispose of or recycle drained oil or the solvent used for cleaning
parts in an appropriate manner.
• Do not attempt to top off the fuel tank after the fuel pump nozzle
shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel spray
and possibly a fire.
• Clean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.
• Replace oil seals, gaskets, packings, O-rings, locking washers,
cotter pins, self-locking nuts, etc. with new ones.
• Replace inner and outer races of tapered roller bearings and needle bearings as a set.
• Arrange the disassembled parts in accordance with their assembled locations and sequence.
• Do not touch the terminals of electrical components which use microcomputers (such as ECM).
Static electricity may damage internal electronic components.
• After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection.
• Use only the fluids and lubricants specified in this manual.
• Use approved bonding agent, sealants or their equivalents when required.

5. Install Tools.
6. Start the engine and warm it up to normal operating temperature.
7. Check the engine oil pressure with engine running under no-load.
Engine oil pressure [Engine oil temperature at 80°C (175°F)]
Unit: kPa (kg/cm2
, psi)
CAUTION:
If the difference is extreme, check the oil passages and oil pump for leaks and blockages.
8. After the inspections, install oil pressure switch as follows:
a. Remove old liquid gasket adhering to oil pressure switch and engine.
b. Apply liquid gasket and tighten oil pressure switch to the specification.
Use Genuine RTV Silicone Sealant or equivalent. Refer to GI-45, "
Recommended Chemical Prod-
uct and Sealant".
c. After warming up engine, make sure there is no leakage of engine oil with engine running.
Changing Engine OilINFOID:0000000003531556
CAUTION:
• Be careful not to burn yourself, as the engine oil is hot.
• Prolonged and repeated contact with used engine oil may
cause skin cancer; try to avoid direct skin contact with used
engine oil. If skin contact is made, wash thoroughly with soap
or hand cleaner as soon as possible.
1. Remove engine front undercover using power tool.
2. Warm up engine, and check for oil leakage from engine compo-
nents. Refer to LU-8, "
Inspection".
3. Stop engine and wait for 10 minutes.
4. Loosen oil filler cap, then remove drain plug.
5. Drain engine oil.
6. Install drain plug with new washer.
CAUTION:
• Be sure to clean drain plug and install with new washer.
