DTC CONFIRMATION PROCEDURE

CAUTION:

If “

EC-1042, "Diagnosis Procedure"

” is unfinished, be sure to perform Step 3 and 4.

1.

PRECONDITIONING-1

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure

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.

TEST CONDITION:

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

>> GO TO 2.

2.

PRECONDITIONING-2

Is “Diagnosis Procedure” of DTC P0524 finished?

YES

>> GO TO 3.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

TESTING CONDITION:

Before performing the following procedure, confirm that battery voltage is 10 V or more at idle.

2. Turn ignition switch ON.

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

4. Turn ignition switch ON.

5. On the CONSULT screen, select “ENGINE” >> “DATA MONITOR” >> “COOLAN TEMP/S”.

6. Check “COOLAN TEMP/S” indication value.

With GST

Follow the procedure “With CONSULT” above.
Is the value of “COOLAN TEMP/S”

−5°C (23°F) and 45°C (113°F)?

YES

>> GO TO 2.

NO-1 [if it is below 

− 5°C (23°F)]>>Warm up the engine until the value of “COOLAN TEMP/S” indicates −5°C

(23

°F) and 45°C (113°F). And then GO TO 2.

NO-2 [if it is above 45

°C (113°F)]>>Cool the engine down to the value of “COOLAN TEMP/S” indicates −5°C

(23

°F) and 45°C (113°F). And then GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

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