Interior rearview mirror

Electrochromic rearview mirror interior receives power and signals on three wires. The mirror has two sensors that detect the brightness of the light falling on them (Fig. 10.27). Sensor brightness of light directed forward, determines the level of outdoor lighting needed for the mirror. Sensor brightness of light directed back, catches the light (glare) by lighting the mirror from the rear of the vehicle. When capturing flare sensor transmits a signal mirror, on the basis of which there is an auto-dimming mirror. Mirror darkens to a level determined by the sensor rearward. Once the sensor ceases to catch glare, the mirror returns to its normal state.
Check Check the ability to mirror darkens as follows: - Switch on the ignition; - Close the brightness sensor light directed forward; - Shine a flashlight on the sensor brightness of light directed back. Mirror should begin to dim as soon as the sensor detects a high level of light.
A WARNING If the test is carried out in a bright place, the mirror may dim as soon as the sensor is closed, the forward direction. |
When the vehicle is reversing mirror should not dim. Point the flashlight on the sensor towards the front and light another torch - sensor aiming ago - should not obscure the mirror.
