EDS001W0
NOTE:
Slow flashing: 1 time/2 seconds
DIAGNOSTIC PROCEDURE
1. CHECK TIRE
Check the following.

Tire pressure

Wear condition

Longitudinal tire size (There shall be no difference of tire size between front and rear tires.)
OK or NG
OK >> GO TO 2.
NG >> Drive at vehicle speed of 20 km/h (12 MPH) or more for 5 seconds or more after repairing or
replacing damaged parts. (Initialize improper size tire information.)
2. CHECK INPUT SIGNAL OF TIRE DIAMETER
With CONSULT-II

2. Drive at 20 km/h (12 MPH) or more for approx. 200 seconds.
3. Select “DATA MONITOR” mode for “ALL MODE AWD/4WD” with CONSULT-II.
4. Check monitor “DIS-TIRE MONI”.
Display of
“DIS-TIRE MONI”
“0-4mm”>>INSPECTION END
Except for “0-4mm”>>GO TO 3.
3. CHECK 4WD CONTROL UNIT
Check 4WD control unit input/output signal. Refer to TF-30, "
4WD Control Unit Input/Output Signal Reference
Va l u e s" .
OK or NG
OK >> GO TO 4.
NG >> Check 4WD control unit pin terminals for damage or loose connection with harness connector. If
any items are damaged, repair or replace damaged parts.

4. Be sure there is no foreign material in reservoir tank. Refill with
new brake fluid.
5. Connect a vinyl tube to bleed valve.
6. Rest foot on brake pedal. Loosen bleed valve. Slowly depress
pedal until it stops. Tighten bleed valve. Release brake pedal.
Repeat this process a few times at 2-3 second intervals until
new brake fluid flows out.
For bleeding procedure. Refer to BR-9, "
Bleeding Brake Sys-
tem" .
Bleeding Brake SystemEFS000C4
CAUTION:

Carefully monitor brake fluid level at master cylinder during bleeding operation.

Fill reservoir with new brake fluid “DOT 3” or “DOT 4”. Make sure it is full at all times while bleed-
ing air out of system.

Place a container under master cylinder to avoid spillage of brake fluid.

While bleeding, pay attention to master cylinder fluid level.

For models with ABS, turn ignition switch OFF and disconnect ABS actuator connectors or bat-
tery ground cable.

Bleed air in the following order.
Right rear brake, left front brake, left rear brake, right front brake
1. Turn OFF ignition switch. Remove ABS actuator connector.
2. Connect a vinyl tube to bleed valve.
3. Fully depress the brake pedal 4 to 5 times.
4. With brake pedal depressed, loosen air bleeder and bleed air.
5. Close bleed valve.
6. Slowly release brake pedal.
7. Tighten bleed valve to the specified torque.
8. Repeat steps 2 - 7. Occasionally refill master cylinder reservoir tank. Be sure to keep it at least half-full.

Disassembly and AssemblyEFS001CH
MODELS WITHOUT ESP (PISTON STOPPER APPLIED.)
Disassembly
CAUTION:
Remove master cylinder reservoir tank only when necessary.
1. Using a slotted flat-bladed screwdriver as shown in the figure,
lever up stopper cap tabs and remove stopper cap. While
removing, be sure to hold cap securely to prevent the master
cylinder piston from popping out.
2. Secure cylinder body flange in a vise as shown in the figure.
CAUTION:

Secure cylinder body flange with chamfered pin insert
hole, facing upward.

When securing in the vise, use copper plates or cloth to
protect the flange.
3. Using a pin punch [tool: diameter Approx. 4 mm (0.16 in)],
remove reservoir tank mounting pins.
4. Remove master cylinder assembly from the vise.
5. Remove reservoir tank and grommet from the cylinder body.
6. Using a Phillips flat-bladed screwdriver, press and hold piston
pin as shown in the figure. Remove piston stopper from the cyl-
inder body.
7. Carefully pull primary piston assembly straight out to prevent
damage to the cylinder inner wall.
8. Tap flange against a wood block to loosen secondary piston
assembly. Carefully pull secondary piston assembly straight out
to prevent damage to the cylinder inner wall.
Inspection After Disassembly

Check cylinder inner wall for damage, wear, corrosion, and pinholes. Replace cylinder if damage, wear, or
corrosion is detected.

CAUTION:

Do not reuse reservoir tank mounting pin.

Do not reuse reservoir tank.

Be sure to insert pin from the chamfered pinhole on the cylinder body.
MODELS WITHOUT ESP (PISTON STOPPER NOT APPLIED.)
CAUTION:
Remove reservoir tank only when absolutely necessary.
Disassembly (Piston Assembly)
1. Using a flat-bladed screwdriver as shown in the figure, lift up the
tabs on the stopper cap and remove it from the master cylinder.
NOTE:
Remove stopper cap while holding it because the piston in mas-
ter cylinder may pop out.
2. Carefully pull primary piston assembly straight out to prevent the
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 inner wall of cylinder for damage, abrasion, corrosion, and pinholes. Replace the 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 the inner cylinder walls, the
piston, or the 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 fluid to cylinder inner wall body and contact surface of the
piston assembly. Then insert secondary piston assembly and
primary piston assembly into cylinder body in this order.
CAUTION:

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

Be sure to replace the assembly without disassembling
the new inner kit.

Do not reuse the primary and secondary piston assem-
blies.

3. Tilt reservoir tank as shown in the figure for the mounting pin to
be inserted. Return the reservoir tank to the upright position
when mounting pin passes through pinhole in the cylinder body.
Push mounting pin to the opposite pinhole of the reservoir tank,
so that it is the same condition as the insertion side.
CAUTION:

Be sure to insert pin from the chamfered pinhole of cylin-
der body.

Do not reuse the mounting pin.
MODELS WITH ESP
Disassembly
CAUTION:

While working, cover primary piston rod with cloth to prevent it from being damaged.

Only remove reservoir tank when absolutely necessary.
1. Place the side of cylinder body with chamfering around the pin
insertion hole up, and secure the cylinder body flange section
with a vise as shown in the figure.
CAUTION:
When securing in a vise, use copper plates or cloth to pro-
tect flange.
2. Using a pin punch [commercial service tool: approximately 4
mm (0.16 in) dia.], remove reservoir tank mounting pin.
3. Remove master cylinder assembly from the vise.
4. Remove reservoir tank and grommet from cylinder body.
5. Push in the primary piston and remove stopper pin from the cyl-
inder body secondary-side tank boss hole.
