Universal Transmitter

On some LH models, a Universal Transmitter is standard factory-installed equipment. The universal transmitter transceiver is integral to the Electronic Vehicle Information Center (EVIC), which is located in the overhead console. The only visible component of the universal transmitter are the 3 transmitter push buttons centered between the 4 EVIC push buttons located just rearward of the EVIC display screen in the overhead console. The 3 universal transmitter push buttons are identified with 1, 2 or 3 light indicators so that they be easily identified by sight.

Each of the 3 universal transmitter push buttons controls an independent radio transmitter channel. Each of these 3 channels can be trained to transmit a different radio frequency signal for the remote operation of garage door openers, motorized gate openers, home or office lighting, security systems or just about any other device that can be equipped with a radio receiver in the 288 to 410 MHz frequency range for remote operation. The universal transmitter is capable of operating systems using either rolling code or non-rolling code technology.

The EVIC module displays messages and a small house-shaped icon with 1, 2 or 3 dots corresponding to the 3 transmitter buttons to indicate the status of the universal transmitter. The EVIC messages are:

• Cleared Channels
  
  Indicates that all of the transmitter codes stored in the universal transmitter have been successfully cleared.
• Training
  
  Indicates that the universal transmitter is in its transmitter learning mode.
• Trained
  
  Indicates that the universal transmitter has successfully acquired a new transmitter code.
• Transmit
  
  Indicates that a trained universal transmitter button has been depressed and that the universal transmitter is transmitting.

The universal transmitter cannot be repaired, and is available for service only as a unit with the EVIC module. This unit includes the push button switches and the plastic module. If any of these components is faulty or damaged, the complete EVIC module must be replaced.
