PRECAUTIONS
lVehicle has TCC shudder and/or no TCC apply. Replace only after all hydraulic and electrical diagnoses
have been made. (Converter clutch material may be glazed.)
lConverter is contaminated with engine coolant containing antifreeze.
lInternal failure of stator roller clutch.
lHeavy clutch debris due to overheating (blue converter).
lSteel particles or clutch lining material found in fluid filter or on magnet when no internal parts in unit are
worn or damaged — indicates that lining material came from converter.
The torque converter should not be replaced if:
lThe fluid has an odor, is discolored, and there is no evidence of metal or clutch facing particles.
lThe threads in one or more of the converter bolt holes are damaged.
lTransaxle failure did not display evidence of damaged or worn internal parts, steel particles or clutch plate
lining material in unit and inside the fluid filter.
lVehicle has been exposed to high mileage (only). The exception may be where the torque converter
clutch dampener plate lining has seen excess wear by vehicles operated in heavy and/or constant traffic,
such as taxi, delivery or police use.
EURO-OBD SELF-DIAGNOSIS — EURO-OBD —
lA/T self-diagnosis is performed by the TCM in combination with the ECM. The results can be read through
the blinking pattern of the O/D OFF indicator lamp or the malfunction indicator lamp (MIL). Refer to the
table onAT-42, "
SELF-DIAGNOSTIC RESULT TEST MODE"for the indicator used to display each self-
diagnostic result.
lThe self-diagnostic results indicated by the MIL are automatically stored in both the ECM and TCM mem-
ories.
Always perform the procedure “HOW TO ERASE DTC” onAT-39, "
HOW TO ERASE DTC"to com-
plete the repair and avoid unnecessary blinking of the MIL.
lThe following self-diagnostic items can be detected using ECM self-diagnostic results mode* only when
the O/D OFF indicator lamp does not indicate any malfunctions.
–PNP switch
–A/T 1st, 2nd, 3rd, or 4th gear function
*: For details of EURO-OBD, refer toAT - 3 7 , "
ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION".
lCertain systems and components, especially those related to EURO-OBD, may use a new style
slide-locking type harness connector.
For description and how to disconnect, refer toPG-70, "
HARNESS CONNECTOR".
