HOW TO PERFORM TROUBLE DIAGNOSES FOR QUICK AND ACCURATE REPAIR
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a problem. It is important to fully understand the symptoms
or conditions for a customer complaint.
Make good use of the two sheets provided, ªINFORMATION FROM CUSTOMERº and ªDIAGNOSTIC
WORKSHEETº, to perform the best troubleshooting possible.
CHECK IN
LISTEN TO CUSTOMER COMPLAINTS AND FILL OUT
ªINFORMATION FROM CUSTOMERº, AT-23.
Check for any Service Bulletins.FRefer to FAIL-SAFE Service Notice or Precautions, AT-5.
CHECK A/T FLUID LEVEL AND CONDITION. IF NG, PLACE
CHECK ON THE DIAGNOSTIC WORKSHEET, AT-24.FRefer to A/T Fluid Check, AT-27.

Bleeding Procedure
1. Bleed air from clutch operating cylinder according to the follow-
ing procedure.
Carefully monitor fluid level at master cylinder during bleeding
operation.
a. Top up reservoir with recommended brake fluid.
b. Connect a transparent vinyl tube to air bleeder valve of clutch
damper.
c. Fully depress clutch pedal several times.
d. With clutch pedal depressed, open bleeder valve to release air.
e. Close bleeder valve.
f. Repeat steps (c) through (e) above until brake fluid flows from
air bleeder valve without air bubbles.
2. Bleed air from clutch operating cylinder according to the above
procedure.
3. Repeat the above bleeding procedures 1 and 2 several times.
