DTC Confirmation Procedure
Confirm that battery voltage is normal 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 ON.
Use X-431 3G diagnostic tester to record and clear the DTCs stored in the PEPS system.
Turn ignition switch to LOCK and wait for a few seconds.
Use X-431 3G diagnostic tester to 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 (
).
