CONSULT-II FUNCTIONS
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II BASIC 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. Select “MULTI AV” on “SELECT SYSTEM” screen. If “MULTI
AV” is not indicated, check the following items.
lNAVI contorol unit power supply and ground circuit.
lCONSULT-II data link connector (DLC) circuit
Refer toGI-50, "
CONSULT-II Data Link Connector (DLC) Cir-
cuit".
2. Select diagnosis item on “SELECT DIAG MODE” screen.
SELF-DIAG RESULTS
The self-diagnosis is started and self-diagnostic results are dis-
played by touching “START” after selecting “SELF-DIAG RESULTS”.
lIn CONSULT-II self-diagnosis, self-diagnostic results and error
history are displayed collectively.
lThe current malfunction indicates “CRNT”. The past malfunction
indicates “PAST”.
lIf DTC [U1000], [U1300] are detected, “0” is displayed at TIME.
If it is normal the next time ignition switch is ON, add 1 to the
TIME.
