REVERSE INTERLOCK DOOR MIRROR SYSTEM
Revision: 2007 April2007 M35/M45
REVERSE INTERLOCK DOOR MIRROR SYSTEMPFP:28548
Component Parts and Harness Connector LocationNIS00230
System DescriptionNIS00231
Select one of the door mirror faces by change over switch, and then set the selected mirror face downward/
inward.
This operation is synchronized with the R position operation of A/T control device.
OPERATION CONDITIONS

Ignition switch : ON

Changeover switch : Select either left or right

A/T control device : R position
During the reverse interlock door mirror system, if all of the above conditions are not satisfied, mirror face
returns to original angle.
MIRROR UNGLE MEMORY FUNCTION

During the reverse interlock door mirror operation, the mirror angle can be changed. After adjustment, the
mirror face positions can be memorized (2 positions). For memory setting, Refer to SE-12, "
MEMORY
OPERATION"

Initial setting is downward 7°, inward 1° (both of left and right)
Power supplied at all times

through 50A fusible link (letter F, located in the fuse block and fusible link)

to automatic drive positioner control unit terminal 39 and

to driver seat control unit terminal 33.

to automatic drive positioner control unit terminal 34 and

to driver seat control unit terminal 40.
Ground is supplied

to automatic drive positioner control unit terminals 40 and 48.

through body grounds M16 and M70.

to driver seat control unit terminals 32 and 48.

through body grounds B5, B40 and B131.

to door mirror remote control switch terminal 13

through body grounds M16 and M70.
REVERSE INTERLOCK DOOR MIRROR SYSTEM OPERATION

When the ignition switch is in ON position, A/T control device into R position. Then TCM (in A/T assembly)
detects it and sends the A/T shift position signal to the driver seat control unit via DATA LINE (CAN H,
CAN L).

When selecting either left and right changeover switch, the automatic drive position control unit judges
which door mirror is selected according to the voltage of terminals 2 and 18. And then, it sends the signal
to driver seat control unit via communication signal.

When the driver seat control unit receives the A/T shift position signal and changeover switch signal, it
sends the operation signal to the automatic drive positioner control unit using the communication signal so
that the each mirror sensor voltage stays in a specified value.

Door mirror (RH) selected
Supply the power from terminals 14, 15 and 30 to door mirror (RH) terminals 5, 6 and 7 so that the voltage
of terminals 5 and 21 stays in a specified value. Then, adjust the mirror angle.

Door mirror (LH) selected
Supply the power from terminals 16, 31 and 32 to door mirror (LH) terminals 5, 6 and 7 do that the voltage
of terminals 6 and 22 is the specified value. Then, adjust the mirror angle.
CAN Communication System DescriptionNIS00232
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 UnitNIS00233
Refer to LAN-50, "CAN System Specification Chart"
