Inspection Procedure 12: Does not Shift Sroperly (Some Point)
COMMENTS ON TROUBLE SYMPTOM If some of the shift points are early or late when driving, the cause is probably a malfunction of valve body, or it is due to the characteristics of the INVECS-II system but is not an abnormality.
PROBABLE CAUSES Malfunction of the engine-A/T-ECU
DIAGNOSIS PROCEDURE
STEP 1. Check when the shift points early or late. Q: Are the shift points early or late only when A/T fluid is -20°C or less, or 125°C or more? YES: The symptom is due to characteristics of the INVECS-II system, but is not abnormal. NO: Go to Step 2.
STEP 2. MUT-II/III actuator test Item 14: INVECS-II cancel command. Test drive the vehicle (Refer to Road Test, Inspection procedure 8 ). Check that the gear shifting corresponds to the standard shift line of the shift pattern diagram. Q: Is the check result normal? YES: The inspection is complete. NO: Replace the engine-A/T-ECU.
