REVERSE INTERLOCK DOOR MIRROR SYSTEM

PFP:28548

System Description

NIS000ZV

●

 When switching the door mirror remote control switch position (LH/RH), the system moves driver or pas-
senger door mirror face downward, in relation to the A/T selector lever being shifted to Reverse Position.

●

The mirror position with the reverse gear engaged can be adjusted and the adjusted mirror position can
be stored in memory (2 positions).

●

With reverse gear-linked operation signal, the door mirror control unit– driver side (LCU03) / passenger
side (LCU04) installed on the door panel drives and controls the motors (UP/DOWN, LH/RH).

●

Using the self-diagnostic function and CONSULT-II, system diagnosis can be performed.

OUTLINE OF OPERATION
Operation Conditions

If all of the following conditions are satisfied, starts operating after approximately 0.5 seconds.

●

Ignition switch is in ON position.

●

Set the door mirror remote control switch from the neutral position to right position, or left position.

●

A/T selector lever is in R position.

NOTE:

●

If the conditions for reverse gear-linked operation are satisfied during manual operation, the manual oper-
ation is interrupted and switched to the reverse gear-linked operation.

REVERSE INTERLOCK DOOR MIRROR SYSTEM

End of Operation

If one of the following conditions is satisfied, the reverse gear-linked operation is stopped.

●

When the set angle is reached.

●

When no operation signal or no operation end signal can be received for approximately 2 seconds or
more after BCM actually outputs the reverse gear-linked operation signal.

●

After receiving the operation signal from the door mirror control unit, when BCM has stayed in the status
for 60 seconds.

Return Operation

If one of the following conditions is satisfied, the mirror face returns upward.

●

When the ignition switch is turned OFF.

●

When the A/T selector lever is shifted to any position except R position.

●

When the door mirror remote control switch is in the neutral position.

NOTE:

●

After the above operation, if no operation conditions previously mentioned are satisfied, shifting the A/T
selector lever to R position will not move the mirror face downward.

End of Return Operation

●

Mirror face returns to the original position.

●

When no operation signal or no operation end signal can be received for approximately 2 seconds or
more after BCM actually outputs the reverse gear-linked operation signal.

●

After receiving the operation signal from the door mirror control unit, when BCM has stayed in the status
for 60 seconds.

MIRROR POSITION MEMORY FUNCTIONS

 Equipped with a function which allows memorizing the desired mirror face positions (2 positions each for LH/
RH door mirror).

Memory Operation Conditions

The seat and steering wheel positions are in accordance with memory 1 or memory 2 in the automatic drive
position control. Refer to 

SE-13, "AUTOMATIC DRIVE POSITIONER"

 .

Memory Operation Procedure

1.

Turn ignition switch ON.

2.

Shift the A/T selector lever to R position.

3.

Switch the door mirror remote control switch to right or left, and set the mirror face to the desired angle.

4.

Press the setting button, and within 5 seconds, press the memory switch which stores the current seat
and steering wheel positions for 0.5 seconds or more.

5.

If the memory switch with certain positions stored is used, it turns off for 0.5 seconds after the operation,
and after that it illuminates continuously (for approx. 5 seconds).

6.

If a memory switch with no positions stored is used, it illuminates (for approx. 5 seconds) after the memory
switch operation.

POWER SUPPLY AND GROUND

Power is supplied at all times

●

through 10A fuse[No.8,located in the fuse block (J/B)]

●

to driver side door mirror control unit terminal 8 and 

●

to passenger side door mirror remote control unit terminal 8

●

through 10A fuse[No.3,located in the fuse block (J/B)]

●

to BCM terminal 105.

When ignition switch is ON or START position,
Power is supplied 

●

through 10A fuse[No.9,located in the fuse block (J/B)]

●

to TCM terminal 7.

BCM is connected to driver side door mirror control unit (LCU03) and passenger side door mirror control unit
(LCU04) as DATA LINE A–2 and DATA LINE A–3.
