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 (
).
Diagnosis Procedure
a. Turn off all the electrical equipment and ignition switch.
b. Disconnect the negative battery cable.
c. Disconnect the ABS module connector E-085 and PEPS controller connector I-029.
d. Disconnect the instrument panel wire harness connector I-034 and engine compartment wire harness
connector E-027.
e. Check if wire harnesses are worn, pierced, pinched or partially broken.
f. Look for broken, bent, protruded or corroded terminals.
