NOTE:
If DTC U0284 is displayed with another DTC UXXXX, per
form trouble diagnosis for DTC UXXXX first. Refer to
EC-87, "
DTCIndex".
DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If another DTC Confirmation Procedure is conducted just before this procedure, always turn ignition switch
OFF and wait at least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is 10 V or more with ignition switch
ON.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
1. Turn ignition switch ON and wait at least 5 seconds.
2. Check 1st trip DTC.
Is 1st trip DTC detected?
YES >> Proceed to EC-163, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000012431378
1.INSPECTION START
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Disconnect active grille shutter harness connector.
4. Check the continuity between ECM harness connector and active grille shutter harness connector.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair or replace the error-detected parts.
2.CHECK INTERMITTENT INCIDENT
Check intermittent incident. Refer to GI-42, "
Intermittent Incident".
Is the inspection result normal?
YES >> Replace active grille shutter. Refer to EXT-33, "Removal and Installation".
NO >> Repair or replace the error-detected parts.
