INFOID:0000000001404061

DTC DETECTION LOGIC

DTC CONFIRMATION PROCEDURE

1.

PERFORM DTC CONFIRMATION PROCEDURE

1.

Insert mechanical key into the key cylinder.

2.

Press the ignition knob switch.

3.

Check “Self diagnostic result” with CONSULT-III.

Is DTC detected?

YES

>> Refer to 

XX-XX, "*****"

.

NO

>> INSPECTION END.

Diagnosis Procedure

INFOID:0000000001532029

1.

CHECK NATS ANTENNA AMP. INSTALLATION

Check NATS antenna amp. installation. Refer to 

XX-XX, "*****"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Reinstall NATS antenna amp. correctly.

2.

CHECK NVIS (NATS) IGNITION KEY ID CHIP

Start engine with another registered NATS ignition key.

Does the engine start?

YES

>> • Ignition key ID chip is malfunctioning.

• Replace the ignition key.
• Perform initialization with CONSULT-III.
