* : In the state that horn reminder operates.
CONSULT-II FunctionAIS004MH
The following functions are performed by combining data received and command transmitted via the commu-
nication line from the BCM.
*:Refer to BCS-14, "CAN Communication Inspection Using CONSULT-II (Self-Diagnosis)" .
CONSULT-II INSPECTION PROCEDURE
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 the
data link connector.
3. Turn ignition switch “ON”.
4. Touch “START (NISSAN BASED VHCL)”.
