DTC CONFIRMATION PROCEDURE
1.PREPARATION BEFORE WORK
If another "DTC CONFIRMATION PROCEDURE" occurs just before, turn ignition switch OFF and wait for at
least 10 seconds, then perform the next test.
>> GO TO 2.
2.CHECK DTC DETECTION
With CONSULT
1. Start the engine.
2. Select “Data Monitor” in “TRANSMISSION”.
3. Select “FLUID TEMP”.
4. Maintain the following conditions for 10 seconds or more.
5. Check the first trip DTC. With GST
1. Start the engine and wait for at least 10 seconds. CAUTION:
When the ambient temperature is less than −20 °C ( −4 °F) and the engine is cold, warm up the
engine for approximately 5 minutes.
2. Check the first trip DTC.
Is
“P084C”detected?
YES >> Go to TM-341, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000009464297
1.CHECK TCM INPUT SIGNALS
1. Turn ignition switch OFF.
2. Start the engine.
3. Check voltage between TCM harness connector terminals.
