AUTOMATIC DRIVE POSITIONER
Revision: 2007 April2007 M35/M45
EXITING OPERATION
When exiting, when the condition is satisfied, the seat is moved backward 40 mm (1.57 in) from normal sitting
position and the steering is moved to the most upper position and front position.
The seat slide amount and the steering operation at entry/exit operation can be changed by set switch, CON-
SULT-II and display (located in the instrument panel). Refer to SE-16, "
SETTING CHANGE FUNCTION" .
Operation Condition

Ignition switch: OFF / Driver side door switch: ON (OPEN)
If the following conditions are not satisfied, exiting operation is not performed.

Ignition switch is in OFF position.

A/T selector lever position is in P position.

Vehicle speed is less than 7 km/h. (4 MPH).

Driver side power seat switch and ADP steering switch are not operated.

Seat memory switch and set switch is not operated.

Door mirror control switch is not operated at change over switch is in LH or RH position.

Output malfunction is not detected.

Detention switch malfunction is not detected.
[Detention switch malfunction is sensed when detention switch remains OFF and vehicle speed is higher
than 7 km/h. (4 MPH).]

CAN communications are normal.

Initialization has been done. Refer to SE-16, "INITIALIZATION PROCEDURE" .
ENTRY OPERATION
When the seat is in the exiting position when either condition (1 or 2) is satisfied, the seat returns from exiting
position to the previous driving position.
Operation Condition
1. Ignition switch: ON
2. Ignition switch: ACC / Driver side door switch: OFF (CLOSE)
If the following conditions are not satisfied, entry operation is not performed.

Ignition switch is in OFF position.

A/T selector lever position is in P position.

Vehicle speed is less than 7 km/h (4 MPH).

Driver side power seat switch, ADP steering switch and door mirror control switch are not operated.

Seat memory switch and set switch is not operated.

Output malfunction is not detected.

Detention switch malfunction is not detected.
[Detention switch malfunction is sensed when detention switch remains OFF and vehicle speed is higher
than 7 km/h (4 MPH).]

CAN communications are normal.

Exiting positions have not been changed during and after exiting operation.

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).

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
Refer to LAN-50, "CAN System Specification Chart" .

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”.
