CONSULT-II Function (AUTO DRIVE POS.) EIS004XO
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.
3. Turn ignition switch ON.40 (B/W) – Ground : Continuity should exist.
48 (B) – Ground : Continuity should exist.

DISPLAY ITEM LIST
NOTE:
If park switch error is detected, manual adjustable pedal operation cannot be performed when ignition
switch turns ON.
The displays of CAN communication and detection switch display error detecting condition from memory
erase to the present on “TIME”.
–If error is detected in the past and present error is detected, “CRNT” is displayed.
–If error is detected in the past and 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 and park switch count error detection frequency occurred after
erase history to “1-127”.
–If error was detected in the past, error detection frequency from memory erase to the present is displayed
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”.
