DTC Confirmation Procedure
Confirm that battery voltage is over 12 V before performing the following procedures.
Turn ignition switch to LOCK.
Connect X-431 3G diagnostic tester (the latest software) to Data Link Connector (DLC).
Turn ignition switch to ON.
Use X-431 3G diagnostic tester to record and clear the DTCs stored in the ECM.
Select Read Code.
If the DTC is detected, the malfunction indicated by the DTC is current. Go to the diagnosis
procedure - Step 1.
If DTC is not detected, the malfunction indicated by the DTC is intermittent (
).
