Can Communication Inspection Using CONSULT-II (Self-diagnosis)AIS002XL
1. SELF-DIAGNOSTIC RESULT CHECK
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Connect to CONSULT-II, and select “AUTO DRIVE POS.” on the “SELECT DAIAG SYSTEM” screen.
2. Select “SELF-DIAG RESULTS” on “SELECT DISG MODE” screen.
3. Check display content in self-diagnostic results.
Displayed U1000?
Yes >> INSPECTION END
No >> Refer to LAN-4, "
Precautions When Using CONSULT-II" .
