CONSULT-II Functions (Multi AV)NKS0048Z
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
OPERATION 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 data
link connector, and turn ignition switch ON.
3. Touch “START (NISSAN BASED VHCL)”.
4. Touch “MULTI AV”
If “MULTI AV” is not indicated, check the following item.
AV (NAVI) control unit power supply and ground circuit.
CONSULT-II data link connector (DLC) circuit
Refer to LAN-7, "
Precautions When Using CONSULT-II" .
Diagnosis mode Description
SELF-DIAG RESULTS
Performs the connection diagnosis of communication circuit between AV (NAVI) control unit and
system and displays the current and past malfunctions collectively.
The DVD-ROM drive diagnosis of NAVI control unit and the connection diagnosis between NAVI
control unit and GPS antenna can be performed (DVD-ROM drive will not be diagnosed when
no map DVD-ROM is in it)
DATA MONITOR The diagnosis of vehicle signal that is input to the AV (NAVI) control unit can be performed
CAN DIAG SUPPORT MNTRThe transmitting/receiving of CAN communication can be monitored. Refer to LAN-20, "
CAN Diag-
nostic Support Monitor" .
AV COMM MONITOR The transmitting/receiving of a system can be monitored
ECU PART NUMBER The part number of AV (NAVI) control unit can be checked
