DESCRIPTION AND OPERATION
Door Mirror Harness Connectors C0352 and C0353 Pin Details
Operation
1 Mirror adjustment multi-directional switch
2 LH/RH mirror selection switch
The door mirrors are selected by moving the mirror selection switch. Moving the switch to the left allows LH door mirror
adjustment. Moving the switch to the right allows adjustment of the RH door mirror.
Movement of the mirror glass in the horizontal and vertical axis is by a dual-motor drive operated by the mirror
adjustment multi-directional switch.
There is a maximum adjustment operating time of 10 secs.
Mirror Memory
Available as optional equipment, the seat, mirror and steering column memory functions are integrated in the BCU.
The driver's and front passenger door modules control the mirror memory while the “Seat Memory” peripheral module
controls the seat and steering column memory.
Located on the outboard side of the driver's seat plinth, the memory switch and memory pre-set buttons can store
three different mirror positions. When a position is stored or recalled, the information is transmitted to the BCU via the
K-bus. It is then relayed to the switching centres via the P-bus. Each switching centre evaluates the recalling and
storage commands transmitted via the P-bus for positions 1 to 3 and performs the necessary adjustments.
If a manual adjustment is selected while the mirror memory is operating, it will over-ride the memory recall function.
For mirror memory to operate, the mirror adjustment potentiometers must deliver a voltage value in the range from
80mV - 4.8V. Should a voltage applied be outside of this range the mirror will not operate when memory is selected.
Pin No.
