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.

Diagnosis Procedure

HINT:
After the fault is eliminated, verify DTC and symptom again.
