On-vehicle Inspection and Adjustment ECS00GVX
1. Check to see if the master cylinder rod end floats freely. It
should not be bound by the clutch pedal.
a. If the rod end is not free, 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.
c. Verify that the master cylinder rod end floats freely. It should not
be bound by the clutch pedal.
d. If the rod end is still not free, remove the rod end and check for
deformation or damage. 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 pedal up and down to determine if it moves
freely.
b. If any sticking is noted, replace the clutch pedal assembly. Re-verify that the master cylinder rod end floats
freely.
3. 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).
Clearance C : 0.74 - 1.96 mm (0.0291 - 0.0772 in)

4. 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).
5. Check the clutch hydraulic system components (clutch master cylinder, clutch operating cylinder, clutch
withdrawal lever and clutch release bearing) 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-8, "
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.Clearance A : 0.74 - 1.96 mm (0.0291 - 0.0772 in)

Air Bleeding ProcedureECS00FSY
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 the air from the system.
CAUTION:

Carefully monitor fluid level in reservoir tank during bleeding operation.

Keep painted surface of body and other parts free of clutch fluid. If it spills, wipe up immediately
and wash the affected area with water.

First bleed the air from the operating cylinder air bleed
valve (1) and then from the bleed connector air bleed valve.
1. Connect a transparent vinyl tube and container to the air bleeder
valve on the clutch operating cylinder.
2. Fill reservoir tank with new clutch fluid.
3. Depress and release the clutch pedal slowly and fully 15 times
at an interval of 2 to 3 seconds.
4. With pedal depressed, continue the bleeding procedure.
5. Push the lock pin (1) of the bleeding connector (2) into the
locked position.
CAUTION:
Hold it to prevent releasing clutch tube from bleeding con-
nector (2) when fluid pressure is applied in the tube.
6. Slide clutch tube (1) in the direction of the arrow as shown, then
bleed the air from the tube.
7. Return clutch tube (1) and lock pin (2) to their original positions.
8. Release clutch pedal and wait for 5 seconds.
9. Repeat steps 2 to 8 until no bubbles are observed in the clutch
fluid.
