PRECAUTIONS
●Converter is contaminated with engine coolant containing antifreeze.
●Internal failure of stator roller clutch.
●Heavy clutch debris due to overheating (blue converter).
●Steel 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:
●The fluid has an odor, is discolored, and there is no evidence of metal or clutch facing particles.
●The threads in one or more of the converter bolt holes are damaged.
●Transaxle 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.
●Vehicle 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 —
●A/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 on AT- 4 2 , "
SELF-DIAGNOSTIC RESULT TEST MODE" for the indicator used to display each self-
diagnostic result.
●The 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” on AT- 3 9 , "
HOW TO ERASE DTC" to com-
plete the repair and avoid unnecessary blinking of the MIL.
●The 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 to EC-44, "
ON BOARD DIAGNOSTIC (OBD) SYSTEM" (QR25DE) or EC-
777, "ON BOARD DIAGNOSTIC (OBD) SYSTEM" (QR20DE).
●Certain 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 to PG-68, "
HARNESS CONNECTOR" .
