DTC Confirmation Procedure:
Confirm that battery voltage is between 11 and 14 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), and make it
communicate with vehicle electronic module by the data network.
Turn ignition switch to ON.
Using X-431 3G diagnostic tester to record and clear the DTCs stored in the TCU.
Turn ignition switch to LOCK and wait for a few seconds.
Turn ignition switch to ON, and then select "Read Code".
If 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. Please refer to Intermittent
DTC Troubleshooting.
