Transmission
Cooler Flushing
@@ To prevent in;ury to face and eyos, atwayswear safety glasses ot a face shield when using thetlansmission flusher.
This procedure should be performed before reinstallingthe transmission.
2.
LCheck equipment for wear and cracks before using.Replace any worn or cracked components.
Using the measuring cup. fill the tank with 21 ounces{approximately 213 lull) ol biodegradable flushingfluid (J35944 - 20). Do not substitute with any otherfluid. Follow the handling procedure on the fluidcontaaner.
Secure the flusher filler cap, and pressurize theflusher with compressed air to 550 - 829 kpa (5.6 _
8.45 kgf/cm,, 80 - 120psi). The air line should beequipped with a water trap to ensure a dry air sys-tem.
Hang the flusher under the vehicle.
Attach the flusher discharge hose to the return lineof the transmission cooler using a clamp.
Connect the drain hose to the inlet line on the trans-mission cooler using a clamp.
IMPORTANT:
Securely clamp the opposite end ofthe drain hose to abucket or floor drain.

Turn on the water valve for 1O seconds. lf waterdoes not flow through the cooler, it is completelyplugged, cannot be flushed, and must be replaced.
Depress the trigger to mix the flushing fluid into thewater flow. Use the wire clip to hold the trigger down.
While flushing with the water and flushing fluid fortwo minutes, turn the air valve on for five secondsevery 15 - 20 seconds to create a surging action.AIR PRESSURE: MAX 845 kpa (8.45 kgf/cmr, t20 psi)
Turn the water valve off. Release the trigger, thenreverse the hoses to the cooler so you can flush inthe opposite direction. Repeat steps 8 through 10.
Release the trigger, and rinse the cooler with wate.for one minute.
Turn the water valve off, and the water supply off.
Turn the air valve on for two minutes, or until nomoisture is visible leaving the drain hose. Residualmoisture in the cooler or lines can damage thetransmission.
Remove the flusher from the cooler line. Attach thedrain hose to a container.
Install the transmission, and leave the drain hoseattached to the cooler line.

Description
Hydraulic Flow (cont'dl
Reverse Driving at Constant Speed l2WD)when driving in reverse at a constant speed, the dual pump system functions in two wheel drive mode.The rotation speed of the front and rear wheels is the same, so the speed of the front and rear pumps is also the same,Fluid discharged by the front oil pump is drawn in by the rear oil pump and is circulated through the system. But, becausethe there is a difference in the capacity between the two pumps, fluid flows through check valve E, and then through ori-Iices. This fluid lubricates and cools the clutch assembly and bearings.ls this condition, only a low pressure is built up at the clutch piston. Therefore the clutch does not engage, and the vehicleremains in 2WD (front wheel drive).
Reverse Deceleration l/tWDl
During reverse deceleration, the dual pump system can engage four wheel drive.When decelerating in reverse direction, the speed of the rear wheels may exceed the speed of the front wheels (due toengine braking). In this condition, the rear oil pump draws fluid through check valves B and C. Fluid discharged from therear oil pump then flows through check valve E to the clutch piston. There, pressure is regulated by two orifices.The regulated hydraulic pressure at the clutch piston may force the plates and discs of the clutch together to form a con,nection. The engaged clutch passes driving force from the transfer assembly to the rear wheels, producing 4WD.

5. Submerge the valve in a container of power steer-
ing fluid or solvent, and blow in the hose. lf air bub-
bles leak through the valve at less than 98 kPa
(1.0 kgflcm', 14.2 psi), repair it as follows ('97 model).
For'98 - 00 models, the flow control valve cannot
be disassembled; replace the pump as an assembly

Clean all the parts in solvent, dry them otf, then
reassemble and retest the valve.
The relief pressure is adjusted at the factory by
adding shims under the check ball seat lf you found
shims in your valve, be sure you reinstall as many
as you took out.
lf the flow control valve tests OK, reinstall it in the
pump. It the flow control valve still leaks air, replace
the pump as an assembly. The flow control valve is
not available separately.

Ball Bearing:
'1. Inspect the ball bearing by rotating the outer race
slowly. lf any play or roughness is felt, replace the
ball bearing.
2. Replace the ball bearing using a press.

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.
