DTC CONFIRMATION PROCEDURE
CAUTION:
Be careful of the driving speed.
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
CAUTION:
At the same time, the accelerator pedal angle must be maintained constant.
Is “P0846”detected? YES >> Go to TM-192, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK TCM INPUT SIGNAL
Is the inspection
result normal?
YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> There is a malfunction of secondary pressure sensor value. Replace transaxle assembly. Refer to TM-283, "Removal and Installation".

Is the inspection
result normal?
YES >> GO TO 2.
NO >> Repair or replace malfunctioning parts.
2.CHECK CIRCUIT BETWEEN TCM AND CVT UNIT (PART 2)
Check continuity between TCM harness connector terminals and ground.
Is the inspection
result normal?
YES >> GO TO 3.
NO >> Repair or replace malfunctioning parts.
3.CHECK TCM INPUT SIGNALS
Is the inspection
result normal?
YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> There is malfunction of secondary pressure sensor. Replace transaxle assembly. Refer to TM- 283, "Removal and Installation".

Diagnosis description : malfunction indicator lamp (MIL)
When emission-related ECU detects a malfunction in the emission
control systems components and/or the powertrain control components
(which affect vehicle emissions), it turns on/blinks MIL to
inform the driver that a malfunction has been detected.
The MIL illuminates when ignition switch is t ...
