8. CHECK GROUND CIRCUIT (AUTOMATIC DRIVE POSITIONER CONTROL UNIT)
Check continuity between the automatic drive positioner control unit connector M50 terminal 40 (B), 48 (B)
and ground.
OK or NG
OK >> Driver seat control unit circuit is OK.
NG >> Repair or replace harness between automatic drive
positioner control unit and ground.
CONSULT-II FunctionAIS002YF
The following functions are performed by combining data received and command transmitted via the commu-
nication line from the driver seat control unit.
*1: For setting automatic drive positioner functions only.
*2: Refer to BL-40, "
Data Monitor" .
*3: During vehicle driving, do not perform active test.
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) – Ground : Continuity should exist.
48 (B) – Ground : Continuity should exist.

NOTE:

The displays of CAN communication and P range 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 P range 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”.
