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).

As soon as the sun visor is removed from the 
holder, the illuminated mirror looses contact.

 To use the illuminated mirror the sun 

visor must remain arrested in the holder 
The illuminated mirror does not function 
as long as the sun visor is outside the 
holder.

 

 

 This malfunction is frequently incorrectly 

diagnosed as a defective lead or sun visor 
contact fault.

 The sun visor and illuminated mirror 

function properly and should NOT be 
replaced.
