DTC CONFIRMATION PROCEDURE

CAUTION:

• Be sure to perform “

TM-386, "Diagnosis Procedure"

” and then perform “DTC CONFIRMATION PRO-

CEDURE”.

• Never perform “DTC CONFIRMATION PROCEDURE” before the repairs. Doing so may result in a sec-

ondary malfunction.

• 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 20 seconds or more.

4. Stop the vehicle.

5. Check the first trip DTC.
Is “P0965”detected?

YES
