CERTAIN MOTOR HOMES BUILT ON GM CHASSIS FAIL TO CONFORM TO THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 108, “LAMPS, REFLECTIVE DEVICES, AND ASSOCIATED EQUIPMENT.” THE ANTI-LOCK BRAKE SYSTEM (ABS) MODULE IS PROGRAMMED INCORRECTLY. WHEN THE BRAKES ARE APPLIED, THE STOP LAMPS WILL ILLUMINATE. WHEN THE BRAKE PEDAL IS RELEASED AND THE STOP LAMPS ARE NO LONGER ILLUMINATED BUT THE REAR BRAKES MAY STILL BE APPLIED. THE BRAKE MAY RELEASE AFTER A FEW SECONDS OR AFTER THE NEXT FIRM BRAKE PEDAL APPLICATION.
