lnspection and Adjustment
Pump Pressure Gheck With T/N 07406 - 0010001
Check the fluid pressure as follows to determine whetherthe trouble is in the pump orgearbox.
1. Check the powsr steering fluid level (see page 17-15), and pump belt tension (see page 17-14).
2. Disconnect the pump outlet hose from the pump
outlet with care so as not to spill the pow€r steeringiluid on the frame and other pans. thon install theP/S joint adapter (pumpl on the pump outlet.

6. Fully open the pressure controlvatve.
7. Start the engine and let it idle.
8. Turn the steering wheel from lock-to-lock severaltimes to warm the fluid to operating temperature.
9, Measure steady-state fluid pressure while the engineis idling. lf the pump is in good condition, the gauge
should read less than 1,500 kPa (15 kgf/cmr, 213 psi).
lf it reads high, check the outlet hose or valve bodvunit (see General Troubleshooting).
10. Close the pressure control valve, then close theshut-off valve gradually until the pressure gauge
nsedle is stable. Read the pressure.
CAUTION: Do not k€ap tha prca3un control valvoclorod mo.c thon 5 srconds or thc pump cluld bodamEgod by ovor-hoating.
11. lmmodiately open the pressure controlvalve fullv.
lf the pump is in good condition, the gauge shouldread at least 6,900 - 7,800 kpa (70 - 80 kgflcmr,'1,000 - 1.140 psi). A low reading means pump out-put is too low for full assist. Repair or replace theDUMD.

Power Steering Gearbox
Removal
Note these items during removal:
. Using solvent and a brush, wash any oil and dirt off
the valve body unit its lines, and the end if the gear-
box. Blow dry with compressed air.
. Be sure to remove the steering wheel before discon-
necting the steering joint. Damage to the cable reel
can occur.
. With 4WD. tilt the engine with a jack to expand the
clearance between the transfer assembly and rear
beam when removing the steering gearbox from the
rear oeam.
Do not remove the steering gearbox by removing the
transfer assembly from the transmission.
1. Drain the power steering fluid as described on page'17-15.
Raise the vehicle, and suppon it on safety stands in
the proper locations (see section 1).
Remove the front wheels,
Remove the drive/s airbag assembly {see section 24).
Remove the steering wheel {see page 17-18).
Remove the steering joint bolts, then disconnect the
steering joint by moving the joint toward the column.

Install the 10 mm hex nut on the ball joint. Be sure
that the 10 mm hex nut is flush with the ball joint
pin end, or the threaded section of the ball joint pin
might be damaged by the special tool. Refer to sec-
tion 18 for ball joint remover usage instruction, Be
careful not to damaging the ball joint boot.
Separate the tie-rod ball joint and knuckle using the
special tool.
Remove the right and left tie-rod ends, then extend
the rack all the way to the right.
Remove the TWC (see section 9).

engine vacuum supply, and maintain an engine
speed that will deliver 66 kPa (500 mmH9, 20 in Hg)

lf the clearance between the gauge body and

between the gauge body and adjusting nut is 0 mm,
the pushrod-to-piston clearance is 0.4 mm (0.02 in)
or more. Therefore it must be adjusted and
recheck€d.
lf clearance is incorrect, loosen the star locknut, and

Brake Booster Inspection
FunctionalTest
1. With the engine stopped, press the brake pedal sev-
eral times to deplete the vacuum reservoir. thenpress the pedal hard, and hold it for 15 seconds. lf
the pedal sinks, either the master cylinder is
bypassing internally, or the brake system (master
cylinder, lines, modulator, proportioning valve. or
caliper) is leaking.
2. Start the engine with the pedal pressed. lf the pedal
sinks slightly. the vacuum booster is operating nor-
mally. lf the pedal height does not vary, the booster
or check valve is faultv.
3. With the engine running, press the brake pedal light-
ly. Apply just enough pressure to hold back auto-
matic transmission creep. lf the brake pedal sinks
more than 10 mm (3/8 in.) in three minutes, the mas-
ter cylinder is faulty. A slight change in pedal height
when the Ay'C compressor cycles on and off is nor-
mal. (The Ay'C compressor load changes the vacuum
available to the booster.)
Leak Test
1.Press the brake pedal with the engine running, then
stop the engine. lf the pedal height does not vary
while pressed for 30 seconds, the vacuum booster is
OK. lf the pedal rises, the booster is faulty.
With the engine stopped, press the brake pedal sev-
eral times using normal pressure. When the pedal is
first pressed. it should be low, On consecutive appli-
cations, the pedal height should gradually rise. lf thepedal position does not vary. check the booster
check valve.
Boostor Chock Valve Test
1. Disconnect the brake booster vacuum hose at the
booster.
2. Start the engine, and let it idle. There should be vac-
uum. lf no vacuum is available, the check valve is
not working properly. Replace the brake booster
vacuum hose and check valve. and retest.

Kickback'1. The motor operates when the ABS is functioning. and the fluid in the reservoir is forced out to the master cylinder,
causing kickback at the brake pedal.
2. The ABS control unit operates the solenoid valve when the brake pedal is released after the initial diagnosis You may
hear the solenoid valve operate at this time, but it is normal
Pumo Motol
1. The pump motor operates when the ABS is functioning
2. The ABS control unit checks the pump motor operation during acceleration. You may hear the motor operate at this
time, but it is normal.
Brake Fluid Replacement/Ail Bleeding
L Brake fluid replacement and air bleeding procedures are the same as for vehicles without ABS To ease bleeding, start
with the front wheels.
Troubleshooting
1. The troubleshooting flowchart procedures assume that the cause of the problem is still present and the ABS indicator
is still on. Following the flowchart when the ABS indicator does not come on can result in incorrect diagnosis.
2. Ouestion the customer about the conditions when the problem occurred, and try to reproduce the same conditions
for troubleshooting.
Self-diagnosis is made at various times such as the initial diagnosis, except ABS control, during ABS control, during
acceleration, during the specified vehicle speed, etc. Therefore, the symptom canngt be checked unless the check
conditions match with the problem conditjons
3. When the ABS jndicator does not come on during the test-drive. but troubleshooting is performed based on the DTC,
check lor loose connectors, poor contact of the terminals, etc., before you start troubleshooting.
4. After troubleshooting, erase the DTC and test-drive the vehicle. Be sure the ABS indicator does not come on.
5. The connector illustratjons show the female terminals with a single outline and the male terminals with a double out-
l ne.
ABS Function Test
To simulate ABS operation and activate the solenoid valves and pump, use the Honda PGM Tester.
Connect the PGM Tester to the 16P Data Link Connector (DLC). When the System Select menu is displayed, select the ABS
Test Mode menu, and follow the tester's prompts.
