CONSULT-II INSPECTION PROCEDURE
CAUTION:
If CONSULT-II is used with no connection CONSULT-II CONVERTER, malfunctions might be detected
in self-diagnosis depending on control unit which carry out CAN Communication.
1. Turn ignition switch OFF.
2. Insert IVIS (NATS) program card into CONSULT-II.
3. Connect CONSULT-II and “CONSULT-II CONVERTER” to data
link connector.
4. Turn ignition switch ON.
5. Touch “START”.
6. Touch “OTHER”.
7. Perform each diagnostic test mode according to each service
procedure.

CONSULT-II DIAGNOSTIC TEST MODE FUNCTION
NOTE:
When any initialization is performed, all ID numbers previously registered will be erased and all ignition key or
mechanical key must be registered again. The engine cannot be started with an unregistered key. The system
will show “DIFFERENCE OF KEY” or “LOCK MODE” as a self-diagnostic result on the CONSULT-II screen.
HOW TO READ SELF-DIAGNOSTIC RESULTS
CONSULT- II DIAGNOSTIC TEST MODE Description
C/U INITIALIZATIONWhen replacing any of the following three components, C/U initialization is necessary.
[IVIS (NATS) ignition key/ BCM/ ECM]
SELF- DIAGNOSTIC RESULTS Detected items (screen terms) are as shown in the chart.
