On certain vehicles, the generic electronic module (GEM) may experience a condition referred to as "lock-up" in which the GEM controlled functions (front windshield wipers, interior lights, 4X4 system etc.) could not be turned ON or, in some cases if the function in ON, it could not be turned OFF. During this lock-up condition, these functions remain in their last known operating mode and do not respond to driver commands until electrical power is interrupted to the GEM. An inoperative front windshield wiper system could adversely affect driver visibility. Correction: Dealers will install a resistor in the GEM circuit which will prevent the electronic noise on the diagnostic link from affecting the GEM during vehicle operation.
