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 (

See page 15-19

).

Diagnosis Procedure

a. Turn off all the electrical equipment and ignition switch.
b. Disconnect the negative battery cable.
c. Disconnect the PEPS controller connector I-030.
d. Disconnect the engine switch connector I-017.
e. Check if wire harnesses are worn, pierced, pinched or partially broken.
f. Look for broken, bent, protruded or corroded terminals.
g. Check that the related connector pins are in good condition.
