INTRODUCTION
Movement of the door mirrors is controlled from a switch pack located on the drivers door. The switch pack contains 2 non-latching mirror select buttons labelled 'L' and 'R' and a 4-way mirror movement switch. Door mirror movement commands are transmitted to the driver's door module over the Local Interconnect Network (LIN) bus. The drivers door module transmits any mirror movement commands to the passenger door module over the medium speed Controller Area Network (CAN) bus.
Movement of the door mirrors is carried out by the respective door module. The door modules provide supply and ground paths to the mirror motors and monitor mirror position via potentiometers located in the mirror housings.
An electrochromic interior mirror is mounted on the windshield and contains a forward and a rearward facing light sensor. The light sensors control the auto dimming feature of the interior mirror to reduce glare from the headlights of following vehicles.
When auto-dimming of the interior mirror is required, a supply is provided by the interior mirror to both door mirrors to initiate the door mirror auto-dimming sequence.
Some vehicles may be fitted with an interior mirror featuring an electronic compass with Light Emitting Diode (LED) display. The compass is a self contained unit and does not interface with any other vehicle system or electronic control module. Details of how to set and calibrate the compass can be found in the 'Mirrors' section of the Owner's Handbook.
