DTC DETECTION LOGIC

NOTE:

• If DTC P0090 is displayed with DTC P1197, first perform the trouble diagnosis for DTC P1197.

• DTC P0090 may be displayed when running out of gas.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC CONFIRMATION PROCEDURE has been previously conducted, always perform the following proce-

dure before conducting the next test.

1. Turn ignition switch OFF and wait at least 10 seconds.

2. Turn ignition switch ON.

3. Turn ignition switch OFF and wait at least 10 seconds.

TESTING CONDITION:

• Before performing the following procedure, confirm that battery voltage is 11 V or more at idle.

• Before performing the following procedure, check that the fuel tank is 1/8 full of fuel.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE-I

WITH CONSULT

1. Start engine.

2. Select “COOLAN TEMP/S” in “DATA MONITOR” mode of “ENGNE” using CONSULT.

4. Check 1st trip DTC.

WITH GST

Follow the above steps for “WITH CONSULT”.
Is 1st trip DTC detected?

YES

>> Proceed to  

EC-222, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure
