AUTOMATIC DRIVE POSITIONER
Revision: 2007 April2007 M35/M45
INITIALIZATION PROCEDURE
After reconnecting battery cable, perform initialization procedure A or B. If initialization has not been per-
formed, EXITING OPERATION will not operate.
Procedure A
1. Turn ignition switch from ACC to OFF position.
2. Driver door switch is ON (open) → OFF (close) → ON (open).
3. END
Procedure B
1. Drive the vehicle at more than 25 km/h (16 MPH).
2. END
SETTING CHANGE FUNCTION
The settings of the automatic driving positioner system can be changed, using CONSULT-II and the display
unit in the center of the instrument panel.
×: Applicable –: Not applicable
It is possible to set sliding driver seat for entry/exit of vehicle by pressing set switch.
CAN Communication System DescriptionNIS0025S
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitNIS0025T

CONSULT-II Function (AUTO DRIVE POS.)NIS00260
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II START PROCEDURE
Refer to GI-38, "CONSULT-II Start Procedure" .
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”.
