CONSULT-II Function (AUTO DRIVE POS.)NIS00260
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
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 (1).
3. Turn ignition switch “ON”.
4. Touch “START (NISSAN BASED VHCL)”.
5. Touch “AUTO DRIVE POS”.
If “AUTO DRIVE POS.” is not indicated, refer to GI-40, "
CON-
SULT-II Data Link Connector (DLC) Circuit" .
AUTO DRIVE POS.
diagnostic modeDescription
WORK SUPPORT Changes settings for each function.
SELF-DIAG RESULTS Displays driver seat control unit self-diagnosis results.
DATA MONITOR Displays driver seat control unit input/output data in real time.
CAN DIAG SUPPORT MNTR The result of transmit/receive diagnosis of CAN communication can be read.
ACTIVE TEST Operation of electrical loads can be checked by sending drive signal to them.
ECU PART NUMBER Driver seat control unit part number can be read.

“ECU PART NUMBER”, “CAN DIAG SUPPORT MNTR” and
“WORK SUPPORT” are available.
SELF-DIAGNOSIS RESULTS
HOW TO READ SELF-DIAG RESULTS
NOTE:
CAN communication malfunction and detention switch malfunction are displayed on “TIME”. (1)
–If error is detected in the present, “CRNT” is displayed.
–If error is detected in the past (present error is not detected), “PAST” is displayed.
–If error has never been detected, nothing is displayed on “TIME”.
Any items other than CAN communication malfunction and detention switch malfunction are counted. (2)
–If error is detected, error detection frequency is displayed from “1” to “127” on “TIME”.
–If error has never been detected, nothing is displayed on “TIME”.
–Can clear the detected memory.
Normal: Clear memory in normal condition, history is erased and nothing is displayed on “TIME”.
Error: Clear memory in error condition, error is detected again and “1” is displayed on “TIME”.
