4. Hold the two outer buttons on the S25 garage door opener for 10 seconds. The LEDs will flash quickly indicating it has entered the diagnostic
mode. Place the J 41540 adjacent to the S25 garage door opener and press each button of the universal home remote one at a time. The tester
should indicate when each button is pressed.
5. Using the Hand Held Transmitter from the J 41540 kit, program a single button on the S25 garage door opener. Verify the Programmed LED on
the test tool lights with the newly programmed vehicle universal home remote. This verifies the transmitter can learn a new function.
‹› If the tester indicates that one or more of the buttons does not respond, replace the S25 garage door opener.
6. Instruct the customer to program the S25 garage door opener. Refer to the vehicle owners manual. If further malfunction occurs, a possible rolling
code or incompatibility with the S25 garage door opener will prevent programming.
