SERVICE BRAKES, AIR:SUPPLY:LOW PRESSURE WARNING:SWITCH
THE INVOLVED VEHICLES FAIL TO MEET FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "AIR BRAKE SYSTEMS", IN REGARD TO INCORRECT PLUMBING IN THE LOW AIR PRESSURE WARNING SYSTEM. AS A RESULT, A LOW AIR PRESSURE CONDITION IN THE REAR BRAKE AIR SUPPLY WILL NOT ACTUATE THE WARNING SYSTEM. THE AUDIBLE ALARM WOULD NOT FUNCTION AND THE DRIVER WOULD NOT BE WARNED OF A BRAKE MALFUNCTION.
Remedy: THE LOW AIR PRESSURE WARNING SYSTEM WILL BE INSPECTED AND CORRECTED, IF NECESSARY, WITHOUT CHARGE.
