AUTOMATIC DRIVE POSITIONER
Revision: 2006 January2006 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

CAN Communication Inspection Using CONSULT-II (Self-Diagnosis)NIS00263
1. SELF-DIAGNOSTIC RESULT CHECK
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. Connect to CONSULT-II, and select “AUTO DRIVE POS.” on the “SELECT DIAG SYSTEM” screen.
2. Select “SELF-DIAG RESULTS” on “SELECT DIAG MODE” screen.
3. Check display content in self-diagnostic results.
