If the Universal Garage Door Opener (UGDO) is inoperative, but the Electronic Vehicle Information Center (EVIC) is operating normally, see the
owner's manual in the vehicle glove box for instructions on training the UGDO. Retrain the UGDO with a known good transmitter as instructed in
the owner's manual and test the UGDO operation again. If the unit is still inoperative, replace the faulty UGDO and EVIC module as a unit. If both
the UGDO and the EVIC module are inoperative, refer to Electronic Vehicle Information Center Diagnosis and Testing for further diagnosis.
