Inspection and Adjustment

1. Check to see if the master cylinder rod end moves freely. It

should not be bound by the clutch pedal. 

• If the rod end does not move freely, remove the rod end and

check for deformation or damage on the rod end. Leave the

rod end removed for step 2. 

2. Check the clutch pedal stroke for free range of movement.
a. With the master cylinder rod end removed, manually move the

clutch pedal up and down to determine if it moves freely.

b. If any sticking is noted, replace the clutch pedal assembly.

Reverify that the master cylinder rod end moves freely. 

3. Inspect the ASCD switch position.
a. If the rod end does not move freely, check that the ASCD switch is not applying pressure to the clutch

pedal causing the rod end to bind. To adjust, disconnect the ASCD switch electrical connector and turn

the ASCD switch.

b. Connect the ASCD switch electrical connector.
4. Adjust clutch interlock switch (1) position so that clearance

between clutch pedal (2) and thread end of clutch interlock

switch (1), with clutch pedal fully depressed, is within specifica-

tion (C).

5. Adjust ASCD clutch switch (1) position so that clearance

between clutch pedal (2) and thread end of ASCD clutch switch

(1), with clutch pedal fully released, is within specification (A).

6. Check the clutch hydraulic system components (clutch master cylinder, CSC) for sticking or binding.
a. If any sticking or binding is noted, repair or replace the related parts as necessary.
b. If any hydraulic system repair was necessary, bleed the clutch hydraulic system. Refer to 

CL-7, "Air

Bleeding Procedure"

.

NOTE:

Do not use a vacuum assist or any other type of power bleeder on this system. Use of a vacuum assist or

power bleeder will not purge all of the air from the system.

Air Bleeding Procedure

INFOID:0000000004499029

CAUTION:

Do not spill clutch fluid onto painted surfaces. If it spills, wipe up immediately and wash the affected

area with water.

NOTE:

• Do not use a vacuum assist or any other type of power bleeder on this system. Use of vacuum assist or

power bleeder will not purge all the air from the system.

• Carefully monitor clutch fluid level in reservoir tank during bleeding operation.

• First bleed the air from the bleeding connector on the CSC and then from the air bleed connector valve.
1. Fill master cylinder reservoir tank with new clutch fluid.
2. Connect a transparent vinyl tube and container to the bleeding

connector (1) on the CSC.

3. Depress and release the clutch pedal slowly and fully 15 times

at an interval of two to three seconds and release the clutch

pedal.

4. Bleed the air from the clutch system according to the following:

1. Push in the lock pin (1) of the bleeding connector (2), and

hold it in.

CAUTION:

Hold the lock pin in to prevent the bleeding connector

from separating when fluid pressure is applied.

2. Slide the bleeding connector (1) away from the transaxle

housing (2) to the specified distance (A) to allow air to bleed

from the clutch system.

3. Depress the clutch pedal and hold it down. 

CAUTION:

Hold the clutch pedal down to prevent air from getting

back into the clutch system.

5. Return the bleeding connector and lock pin to their original positions.
6. Release the clutch pedal and wait for five seconds.
7. Repeat steps 3 through 6 until no air bubbles can be observed in the clutch fluid.
