AUTOMATIC DIMMING INSIDE REARVIEW MIRROR, FUNCTION - GF68.49-P-0003GH
MODEL 163 as of 1.9.99 with CODE (249b) Automatic dimming inside rearview and outside rearview
mirror (driver)
Function requirements
No overvoltage or undervoltage
Term. 15R or 15 ON
Reverse gear not engaged
Interior lighting not switched on
Function
The glass of the inside rearview mirror (A67) can be electro-chromatically dimmed. The mirror glass between
the reflector and the glass cover contains a layer of electrolyte gel. The light transmission ratio of this gel
changes when a voltage is applied to it.
The light hitting the surface of the mirror is more or less reflected due to the variable of the actuation voltage.
The actuation voltage is controlled by the electronic circuitry in the inside rearview mirror. This is
accomplished depending on the ambient light and the light hitting the mirror.
The two input parameters are detected by the mirror dimming to rear sensor (A67h2) in the mirror housing
(rear) and by the mirror dimming forward sensor (A67h1) in the mirror glass of the inside rearview mirror
(A67).
The inside rearview mirror unit (A67) also acts as the master for the outside mirror dimming function
(driver's side).
