The defect
THE WRONG OPERATIONAL AMPLIFIER WAS INSTALLED IN THE CONTROLLER ON THE INVOLVED VEHICLES. IF A CERTAIN CAPACITOR IN THE CONTROLLER SHOULD FAIL, THE BRAKES ON THE AXLE ON WHICH THE CONTROLLER IS LOCATED WOULD FAIL. THE BRAKE WARNING LIGHT WHICH WOULD NORMALLY INDICATE A MALFUNCTION, WOULD ALSO BE INOPERATIVE.
The remedy
THE DEALER WILL INSPECT AND, IF NECESSARY, REMOVE INCORRECT CONTROLLER AND INSTALL A NEW CONTROLLER AND WIRING HARNESS.
