Clutch Master Cylinder Replacement (cont'd)
10. To prevent the retaining clip (A) from coming off,
pry open the tip of the retaining clip (B) with a
screwdriver,
Tighten the master cylinder mounting nuts to 13 N
m (1.3 kgf m, 9.4 lbf.ft).
Bleed the clutch master hydraulic system (see step
1 1 on page 12-8).
NOTE: The reservoir filling is covered in the
bleeding procedure.
lnstallthe air cleaner housing (see step 37 on page
5-15).

Brake System Bleeding
NOTE:. Do not spill brake fluid on the vehicle; it may damage
the painU if brake fluid does contact the paint. wash it
off immediately with water.. The reservoir on the master cylinder must be at the
MAX (upper) level mark at the start of the bleeding
procedure and checked after bleeding each brake
caliper. Add fluid as required.. Do not reuse the drained fluid.. Always use Honda DOT 3 brake fluid. Non-Honda
brake fluid can cause corrosion and shorten the life of
the system.. Make sure no din or other foreign matter is allowed
to contaminate the brake fluid.
1. Make sure the brake fluid level in the reservoir is at
the MAX (upper) level line (A).
Slide a piece of clear plastic hose over the flrst
bleed screw, and submerge the other end in a
container of new brake fluid.
Have someone slowly pump the brake pedal
severaltimes, then apply steady pressure.
Starting at the left-front, loosen the brake bleed
screw to allow air to escape from the system. Then
tighten the bleed screw securely.

ABS Control Unit
Main Control
The ABS control unit detects the wheel speed based on the wheel sensor signal it received, then it calculates the
vehicle speed based on the detected wheel speed. The control unit detects the vehicle speed during deceleration
based on the rate of deceleration.
The ABS control unit calculates the slip rate of each wheel and transmits the control signal to the modulator unit
solenoid valve when the slip rate is high.
The pressure reduction control has three modes: pressure reducing, pressure retaining, and pressure intensifying.
Self-diagnosis Function

2. The CPUS check the circuit of the system.
3. TheABScontrol unitturns ontheABS ind icator when the unitdetectsa problem andthe unit stops th e system.
4. The self-diagnosis can be classified into these two categories:. lnitial diagnosis. Regular diagnosis
On-board Diagnosis Function
The ABS can be diagnosed with the Honda PGM Tester.
The ALB Checker cannot be used with this system. For air bleeding and checking wheel sensor signals. use the Honda
PGM Tester. See the Honda PGM Tester user's manual for specific operating instructions.
