SYMPTOM DIAGNOSIS
Oil Leakage
Notice :
– Careful localization of leakage points may make it
possible to prevent incorrect or cost–intensive re-
pairs.
Test Steps :– Thoroughly clean the transaxle, engine, and sur-
rounding area(using a steam jet, for example).
– To locate leakage, use a suitable identifying spray
or similar product.
– Depending on the amount of leakage, take the
car for a short or a longer test drive – It may prove
sufficient to place the car on a hoist and run the
engine at idle speed to trace the leak.
– If possible, determine exactly which type of oil is
escaping.
Symptom
Possible CauseAction
Transaxle Oil Leak-
ageOil Pump(Torque Converter Sealing)S Visually check torque converter sealing.
S Replace the converter sealing as described in
the transaxle repair on the vehicle service.
Crankshaft Sealing RingS Check whether engine oil or TFT is leaking out.
S If leak is engine oil, replace the sealing ring as
described in the engine repair instruction.
Torque ConverterS Visual check.
S Fit an exchange converter as described in the
repair instruction.
Oil Content Too HighS Check oil level(TFT and axle oil) as described
in this chapter.
S Correct oil level, and recheck after a test drive.
Notice : Comply with the measuring procedure (fill-
ing procedure) in the repair instruction. Check the oil
level at the overflow plug adjust to proper level if nec-
essary.
O–ring at Bolt Head Damaged or Miss-
ingS Check O–ring.
S Replace O–ring as described in the repair in-
struction.
Shaft SealS Visually check the shaft seal.
S Replace the sealing ring as described in the
repair instruction.
Hose Clamp LooseS Check to ensure that the hose clamp fits tightly.
S If necessary, retighten clamp.
Oil Pan Gasket Not Installed ProperlyS Check to see if the gasket was positioned
properly.
S Install gasket properly as described in the re-
pair instruction.
Oil Pan Gasket DamagedS Check the gasket visually.
S Replace gasket as described in the repair in-
struction.
Bolt at Bracket LooseCheck the Tightening Torque
Retighten bolt
Sealing Ring at Oil DipstickS Check O–ring.
S If necessary, replace O–ring.
Sealing Ring Near End–Cover Connec-
tion DefectiveS Check sealing rings.
S Put in new sealing ring Check O–ring as de-
scribed in the repair instruction.

DIAGNOSTIC TROUBLE CODE(DTC) P0562
SYSTEM VOLTAGE LOW
Circuit Description
The transaxle control module(TCM) is an electronic de-
vice which monitors inputs to control various transaxle
functions including shift quality and transaxle sensors,
switches, and components to process for use within its’
control program. Based on this input information, the TCM
controls various transaxle output functions and devices.
Conditions For Setting The DTC
S System voltage is less than 8.5 volts.
S Transaxle input voltage is too low.
S Engine speed is greater than 500 rpm.
S Immediately after the above condition occurs.
Action Taken When The DTC Sets
S The Malfunction Indicator Lamp(MIL) will illuminate.
S The TCM will record operating conditions at the
time the diagnostic fails. This information will be
stored in the Failure Records buffer.S Adopt Emergency/ Substitute mode and constant
4th gear by hydraulic control.
S After ignition OFF/ON : 3rd gear by hydraulic con-
trol. Possible P, R and N also possible.
S Power supply cut off to the EDS valve.
Conditions For Clearing The DTC
S The MIL will turn OFF when the malfunction has
not occurred after three–ignition cycle.
S A history DTC will clear after 40 consecutive warm
up cycles without a fault.
S Using a scan tool can clear history DTCs.
Diagnostic Aids
S Inspect the poor wiring harness connection for TCM
connectors and transaxle wiring connectors.
S Inspect the improperly formed or damaged termi-
nals.

DIAGNOSTIC TROUBLE CODE(DTC) P0601
INTERNAL CONTROL MODULE MEMORY CHECKSUM
ERROR
Circuit Description
A normal function of the Transmission Control Module
(TCM) programming is to perform an internal check that
verifies the integrity of the RAM memory allocations.
The DTC P0601 sets when the Random Access
Memory(RAM) is not operating correctly when checked on
initialization. An area of RAM is failed a read/ write test.
Conditions For Setting The DTC
S The EEPROM checksum test is separated in two
independent parts, the code checksum test and the
calibration checksum test. For each area the check-
sum is calculated and compared with the corre-
sponding checksum valve. If the valves are differ-
ent, the fault will be set.
S System voltage is too high or too low.
S Transaxle input voltage is too high or too low.
S Immediately after the above condition occurs.
Action Taken When The DTC SetsS The Malfunction Indicator Lamp(MIL) will illuminate.
S The TCM will record operating conditions at the
time the diagnostic fails. This information will be
stored in the Failure Records buffer.
S Adopt Emergency/ Substitute mode and constant
4th gear by hydraulic control.
S After ignition OFF/ON : 3rd gear by hydraulic con-
trol. Possible P, R and N also possible.
S Power supply cut off to the EDS valve.
Conditions For Clearing The MIL/DTC
S The MIL will turn OFF when the malfunction has
not occurred after three–ignition cycle.
S A history DTC will clear after 40 consecutive warm
up cycles without a fault.
S Using a scan tool can clear history DTCs.
Diagnostic Aids
S When DTC P0601 sets, the possible cause of fault
could be TCM.
