Auto-Dimming Interior Mirror with Universal Transmitter
The interior mirror incorporates either manual or auto-dimming. Manual dimming is performed with a lever on the underside of the mirror body. Auto-dimming is performed by Electrochromic mirror glass.
Depending on vehicle model and market, the auto-dimming interior mirror may also incorporate a HomeLink(R) universal transmitter.
NOTE: HomeLink is a registered trademark owned by Johnson Controls Inc.
Interior mirrors with the universal transmitter and/or the auto-dimming functions are connected to the vehicle wiring by an electrical connector concealed by covers on the mounting stem. On vehicles with automatic windshield wipers and headlamps, the rain/light sensor is concealed by the covers.
When the ignition switch is in position II, a battery power feed from the CJB (central junction box) is supplied to the universal transmitter and/or auto-dimming circuits in the interior mirror.
Light sensors on the front and rear of the interior mirror provide light level inputs for the auto-dimming function.
Interior mirrors which incorporate the universal transmitter have buttons along the lower face for control of the universal transmitter and auto-dimming functions. They also have a dual colored status indicator on the rear of the mirror which illuminates when the auto-dimming and universal transmitter functions are active; green for auto-dimming and red for the universal transmitter.
Auto-Dimming
The auto-dimming interior mirror automatically dims to reduce glare from the headlights of following vehicles in dark or low light conditions. The auto-dimming function is only enabled while the ignition switch is in position II.
On interior mirrors with a universal transmitter, the auto-dimming function can be selected on and off using the appropriate buttons on the underside of the mirror. At the beginning of each ignition cycle the auto-dimming function defaults to on. The green status indicator is illuminated while the auto-dimming function is on.
On auto-dimming interior mirrors without a universal transmitter, the auto-dimming function is permanently on while the ignition switch is in position II.
When the auto-dimming function is on, the light sensor in the front of the mirror monitors ambient light at the front of the vehicle and the light sensor in the rear of the mirror monitors the light coming from behind the vehicle. When the light from behind the vehicle exceeds the ambient light level, the auto-dimming circuits darken the interior mirror. Dimming is inhibited when reverse gear is selected. The reverse gear signal is provided by a hardwired signal from the reverse relay in the CJB (central junction box).
Universal Transmitter
WARNING: The universal transmitter must not be used with any garage door that lacks a safety stop and reverse feature, as required by federal safety standards (this includes any garage or door opener model manufactured before April 1 1982). A garage door opener which cannot detect an object in the path of a closing door, and then automatically stop and reverse the door, does not meet current federal safety standards. Using a garage door opener without these features increases the risk of serious injury or death.
The universal transmitter can operate up to three home or office remotely operated systems (e.g. garage door/gate openers, lighting and security systems), replacing the individual hand held transmitters required for each system. The universal transmitter operates at radio frequencies from 288 to 419 MHz (excluding 322 to 335.4 MHz and 399.9 to 410 MHz).
The universal transmitter has three channels, with separate operating buttons for each channel. When one of the buttons is pressed the universal transmitter outputs the radio signal programmed for the related channel (if any) and illuminates the red status indicator to confirm transmission.
Hand held transmitters are programmed into the universal transmitter as follows:
WARNING: When programming the universal transmitter in the vicinity of the affected system, the system will operate. If the system controls garage doors or gates, ensure they are clear of people and objects to prevent personal injury or damage to equipment.
^ Turn the ignition switch to position II.
^ Press and hold the outer two buttons of the universal transmitter until the red status indicator begins to flash, then release the buttons. This initializes the universal transmitter and erases previous settings from all three channels.
^ Place the signal emitting end of the hand held transmitter against the underside of the interior mirror.
^ Simultaneously press and hold the activation button on the hand held transmitter and the chosen button of the universal transmitter. When the red status indicator flashes rapidly, indicating the channel has been programmed, release the buttons (The red status indicator flashes slowly at first and can take up to a minute before it flashes rapidly).
^ To program another channel on the universal transmitter, repeat steps C. and D.
^ Turn the ignition switch to 0.
The radio signals used to operate some home/office systems incorporate a code protection feature. After a channel has been programmed from the hand held transmitter, these systems will need to be trained to accept the signal from the universal transmitter. To check if a system is code protected, press the appropriate universal transmitter button. If the red status indicator flashes rapidly for 1 to 2 seconds, before illuminating permanently, the system has a code protection feature.
The system is trained to the universal transmitter, as follows:
^ Locate the training button on the receiver system.
^ Press the training button for 1 to 2 seconds, then perform step C. within 30 seconds.
^ On the vehicle, press and release the appropriate universal transmitter button, twice. The receiver system should now be trained to the universal transmitter.
^ If the system does not operate, repeat the procedure, but in step C. press and release the universal transmitter button three times.
