The customer is able to program one or all of the Homelink buttons using their garage door/gate remote transmitter. After a few days or even weeks,
the button no longer functions. There are no DTCs stored in any control units, and the LED on the button which was once programmed, now flashes
slowly indicating no programming is stored.
The customers transmitter operates at 295Mhz (can be seen on back of transmitter), and the Homelink system loses the original programming to any
one of the three Homelink buttons after a few days or weeks.
Technical Background
The garage door transmitter was designed with an operational frequency range of which the 295Mhz works correctly during the initial programming
of the system. Over time, and especially in warmer climates, the transmitting frequency given out by the factory installed transmitter on the vehicle
can drift out of range, thus causing the system to "lose" its programming.
Production Solution
Design changed for future model releases but current production has not been changed.
