CONSULT-II Inspection ProcedureAIS004R7
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. Turn ignition switch “OFF”.
2. Connect “CONSULT-II” and CONSULT-II CONVERTER to data
link connector.
3. Turn ignition switch “ON”.
4. Touch “START (NISSAN BASED VHCL)”.
5. Touch “BCM”.
If “BCM” is not indicated, go to GI-40
, “CONSULT-II Date Link
Connector (DLC) Circuit”
6. Touch “REAR DEFOGGER”.
