Check CAN Communication System InspectionAIS002XL
1. CHECK SELF-DIAGNOSTIC RESULT
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 CONSULT-II, and turn ignition switch ON.
2. Touch “AUTO DRIVE POS.” on “SELECT SYSTEM” screen.
3. Touch “SELF-DIAG RESULTS” on “SELECT DIAG MODE” screen.
4. Check display content in self-diagnostic results.
Displayed U1000?
