Confirmation Procedure
- PRECONDITIONING-I
If DTC Confirmation Procedure is previously conducted, always perform the following procedure before conducting the next test.
- Turn ignition switch OFF and wait at least 10 seconds.
- Turn ignition switch ON.
- Turn ignition switch OFF and wait at least 10 seconds.
TESTING CONDITION:
Before performing the following procedure, check that battery voltage is 9 V or more with ignition switch ON.
GO TO 2.
- PRECONDITIONING-II NOTE:
- When it is certain that the previous driving is performed with the engine warmed up, the next steps can be performed.
- When it is difficult to satisfy the conditions, performing Component Function Check can identify the presence or absence of malfunction in the part/system that may result in a possible cause of this DTC. (Perform DTC Confirmation Procedure as much as possible.)
- Start the engine and warm it up until engine coolant temperature reaches 70 deg.C (158 deg.F) or more.
- Stop the engine and leave the vehicle in a cool place (soak the engine) until the engine coolant temperature reaches 35 deg.C (95 deg.F) or less.
CAUTION:- The difference between air temperature and engine coolant temperature must be 5 deg.C (9 deg.F) or less.
- Never turn ignition switch ON during soak the engine.
Are the conditions satisfied?
YES
GO TO 4.
NO
GO TO 3.
- COMPONENT FUNCTION CHECK
With CONSULT
- Turn ignition switch OFF.
- Start the engine.
- On CONSULT screen, select "DATA MONITOR" mode of "ENGINE".
- Check the value of "FUEL PRES SEN V" under the following conditions.

Refer to DTC Diagnosis Procedure .
- PERFORM DTC CONFIRMATION PROCEDURE-1
- Turn ignition switch ON (engine stopped).
- On CONSULT screen, select "ENGINE" >> "DATA MONITOR" >> "COOLAN TEMP/S" and "INT/A TEMP SE".
- Check that the indicated value of "COOLAN TEMP/S" is less than 35 deg.C (95 deg.F).
- Check that the difference between "INT/A TEMP SE" and "COOLAN TEMP/S" is 5 deg.C (41 deg.F) or less.
- Check "Self-diagnostic result" of "ENGINE".
Is the DTC detected?
YES
Refer to DTC Diagnosis Procedure .
NO
GO TO 5.
NO
GO TO 2.
- PERFORM DTC CONFIRMATION PROCEDURE-2
- Start the engine (or cranking) at least 1 second.
- Check "Self-diagnostic result" of "ENGINE".
Is the DTC detected?
YES
Refer to DTC Diagnosis Procedure .
NO
To check malfunction symptom before repair: Refer to Inspection .
NO
Confirmation after repair: INSPECTION END
