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.
The fix
THE LOW AIR PRESSURE WARNING SYSTEM WILL BE INSPECTED AND CORRECTED, IF NECESSARY, WITHOUT CHARGE.
