Check Key SwitchBIS000WS
1. CHECK KEY SWITCH INPUT SIGNAL
With CONSULT-II
Check ignition key switch “KEY ON SW” in “DATA MONITOR” mode with CONSULT-II.

When key is inserted in ignition key cylinder

When key is removed from ignition key cylinder
Without CONSULT-II
Check voltage between BCM connector and ground.
OK or NG
OK >> Key switch circuit is OK.
NG >> GO TO 2.
2. CHECK KEY SWITCH
1. Turn ignition switch OFF.
2. Disconnect key switch and key lock solenoid connector.
3. Check continuity between key switch and key lock solenoid terminal 1 and 4.
OK or NG
OK >> Check the following.

15A fuse [No. 17, located in fuse block (J/B)]

Harness for open or short between key switch and
key lock solenoid and fuse

Harness for open or short between BCM and key
switch and key lock solenoid

CAUTION:
Remove reservoir tank only when absolutely necessary.
Disassembly (Piston Assembly)
1. Using a flat-bladed screwdriver as shown in the figure, lift up
tabs on stopper cap and remove it from master cylinder.
NOTE:
Remove stopper cap while holding it because primary piston
assembly in master cylinder may pop out.
2. Carefully pull primary piston assembly straight out to prevent
cylinder inner wall from being damaged.
3. Tap flange using a soft block, such as wood, and carefully pull
secondary piston assembly straight out to prevent cylinder body
inner wall from being damaged.
Inspection After Disassembly (Piston Assembly)
Cylinder body

Check a inner wall of cylinder for damage, abrasions, corrosion, and pinholes. Replace cylinder body if
detected.
Assembly (Piston Assembly)
CAUTION:

Do not use mineral oils such as kerosene, gasoline during the cleaning and assembly process.

Make sure there is no foreign matter such as dirt or dust attached to inner cylinder walls, piston,
or cap seal, and use care to avoid damaging parts with the assembly tools.

Do not drop parts. If a part is dropped, do not use it.
1. Apply brake fluid to cylinder inner wall, piston cups and contact
surfaces between piston assemblies. Then insert secondary pis-
ton assembly and primary piston assembly into cylinder body in
this order.
CAUTION:

Do not reuse primary and secondary piston assemblies.

Be sure to replace piston assemblies without disassem-
bling new inner kit.

Pay attention to the orientation of piston cup, and insert
straight to prevent cup seal from being caught by cylin-
der inner wall.

6. Remove snap ring while pressing in primary piston assembly
into prevent piston from popping out.
7. Hold primary piston rod, and then pull primary piston assembly,
plate, and guide assembly straight out.
8. Remove plate and guide assembly from primary piston assem-
bly.
CAUTION:
When removing plate from primary piston rod, make sure
inside of plate dose not damage rod.
9. Tap flange using a soft block, such as wood, and carefully pull
secondary piston assembly straight out to prevent a cylinder
body inner wall from being damaged.

Do not drop parts. If a part is dropped, do not use it.
1. Apply brake fluid to cylinder inner wall, piston cup seal and con-
tact surfaces between piston assembly. Then insert secondary
piston assembly and primary piston assembly into cylinder body
in this order.
CAUTION:

Do not reuse primary and secondary piston assemblies.

Be sure to replace piston assemblies without disassem-
bling new inner kit.

Pay attention to the orientation of piston cup, and insert
straight to prevent piston cup seal from being caught by
cylinder inner wall.
2. Visually inspect secondary piston assembly slit through piston
stopper mounting hole and then install piston stopper while
pushing in primary piston assembly.

4. Place a wooden block as shown in the figure, and blow air from
union bolt mounting hole to remove pistons and piston boots.
CAUTION:
Do not get fingers caught in pistons.
5. Using a flat-bladed screwdriver, remove piston seal from cylin-
der body.
CAUTION:
Be careful not to damage a cylinder inner wall.
INSPECTION AFTER DISASSEMBLY
Cylinder Body
CAUTION:
Use new brake fluid to clean. Do not use mineral oils such as gasoline or kerosene.

Check inner wall of cylinder for corrosion, wear, and damage. If a malfunction is detected, replace cylinder
body.

Minor flaws caused by corrosion or a foreign material can be removed by polishing a surface of inner wall
with a fine sandpaper. Replace cylinder body, if necessary.
To r q u e M e m b e r
Check for wear, cracks, and damage. If a malfunction is detected, replace torque member.
Piston
CAUTION:
Piston sliding surface is plated. Do not polish with sandpaper.
Check piston surface for corrosion, wear, and damage. If a malfunction is detected, replace applicable part.
Sliding Pin, Sliding Pin Bolt, and Sliding Pin Boot
Check sliding pins and sliding pin boots for wear, damage, and cracks. If a malfunction is detected, replace
applicable part.
ASSEMBLY
1. Apply polyglycol ether based lubricant to piston seal, and install
them to cylinder body.
CAUTION:
Do not reuse piston seal.

ENGINE COOLANT

ENGINE COOLANTPFP:KQ100
InspectionBBS005A2
LEVEL CHECK

Check if the reservoir tank engine coolant level is within the
“MIN” to “MAX” range when engine is cool.

Adjust the engine coolant level as necessary.
LEAK CHECK

To check for leaks, apply pressure to the cooling system with
radiator cap tester (commercial service tool) and radiator cap
tester adapter (SST).
WARNING:
Do not remove radiator cap when engine is hot. Serious
burns could occur from high-pressure engine coolant
escaping from radiator.
CAUTION:
Higher testing pressure than specified may cause radiator
damage.
NOTE:
In a case that engine coolant decreases, replenish radiator with engine coolant.

If anything is found, repair or replace damaged parts.
Changing Engine CoolantBBS005A3
WARNING:

To avoid being scalded, do not change engine coolant when engine is hot.

Wrap a thick cloth around radiator cap and carefully remove the cap. First, turn the cap a quarter
of a turn to release built-up pressure. Then turn the cap all the way.

Be careful not to allow engine coolant to contact drive belt.
DRAINING ENGINE COOLANT
1. Remove grommet from undercover.
2. Open radiator drain plug at the bottom of radiator, and then remove radiator cap.
When drain all of engine coolant in the system, open water drain plug on engine cylinder block.
Refer to EM-81, "
CYLINDER BLOCK" .
3. Remove reservoir tank as necessary, and drain engine coolant and clean reservoir tank before installing.
