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. Remove the fuses EF15 (15 A), EF48 (20 A) and EF43 (20 A) from engine compartment fuse and relay 

box.

d. Remove the IGN1 relay, IGN2 relay and ACC relay from engine compartment fuse and relay box.
e. Check if fuses and relays are blown or damaged. 

a. Check engine compartment fuse and relay box ground E-078 (

See page 51-42

).
