1.

CHECK INTERMITTENT INCIDNT

Refer to

GI-41, "Intermittent Incident"

.

Is the inspection result normal?

YES

>> Replace transaxle assembly. Refer to

TM-415, "Removal and Installation"

.

NO

>> Repair or replace the malfunction items.

OFF".

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

1.

Start the engine.

2.

Drive the vehicle.

3.

Maintain the following conditions for 10 seconds or more.

4.

Stop the vehicle.

5.

Check the first trip DTC.
