Reverse Interlock Door Mirror System: Overview Infiniti Q45 III

System Description

1. When switching the door mirror remote control switch position (LH/RH), the system moves driver or passenger door mirror face downward, in relation to the A/T selector lever being shifted to Reverse Position.
2. The mirror position with the reverse gear engaged can be adjusted and the adjusted mirror position can be stored in memory (2 positions).
3. With reverse gear-linked operation signal, the door mirror control unit-driver side / passenger side (LCU) installed on the door panel drives and controls the motors (UP/DOWN, LH/RH).
4. Using the self-diagnostic function and CONSULT-II, system diagnosis can be performed.

1. When the ignition switch is turned OFF.
2. When the A/T selector lever is shifted to any position except R position.
3. 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

1. Mirror face returns to the original position.
2. 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.
3. After receiving the operation signal from the door mirror control unit, when BCM has stayed in the status for 60 seconds.

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 "AUTOMATIC DRIVE POSITIONER ".

Memory Operation Procedure

1. Turn ignition switch ON.

Wake-Up Diagnosis

1. The wake-up diagnosis is carried out when BCM detects the wake-up signal from each local unit (LCU). When the switch shown on the screen is operated as instructed, each local control unit (LCU) outputs the wake-up signal. If BCM cannot detect a wake-up signal, it is judged malfunctioning. The malfunctioning local control unit (LCU) is displayed on the screen.
