TROUBLE DIAGNOSIS — GENERAL DESCRIPTION
Revision: November 20092006 QX56
CONSULT-II Function (ICC)EKS00BLX
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II OPERATION
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 carries 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 “ICC” on "SELECT SYSTEM" screen.
If “ICC ” is not indicated, go to GI-40, "
CONSULT-II Data Link
Connector (DLC) Circuit" .
ICC diagnostic mode Description
WORK SUPPORT Supports inspections and adjustments. Commands are transmitted to the ICC unit for setting the sta-
tus suitable for required operation, input/output signals are received from the ICC unit and received
data is displayed.
SELF-DIAG RESULTS Displays ICC unit self-diagnosis results. DATA MONITOR Displays ICC unit input/output data in real-time.
CAN DIAG SUPPORT MNTR The results of transmit/receive diagnosis of CAN communication can be read. ACTIVE TEST Operation of electrical loads can be checked by sending driving signal to them.
ECU PART NUMBER ICC unit part number can be read.
