FOUR WINDS INTERNATIONAL
The problem
CERTAIN MOTOR HOMES DO NOT COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, 'AIR BRAKE SYSTEMS.' IN A SITUATION IN WHICH MULTIPLE ALARMS ARE ACTIVE, A CHECK ENGINE, STOP ENGINE, OR SIMILAR WARNING INDICATOR IS GIVEN PRIORITY OVER THE LOW AIR ALARM BY THE INSTRUMENT SYSTEM CONTROLLER SOFTWARE. IF THE OPERATOR DOES NOT ACKNOWLEDGE THESE HIGHER PRIORITY ALARMS, A LOW AIR ALARM MAY NOT BE DISPLAYED.
Risk
A VEHICLE COULD BE DRIVEN WITH THE AIR PRESSURE BELOW 60 PSI WITHOUT THE LOW AIR WARNING SOUNDING, WHICH COULD RESULT IN A CRASH.
What owners should do
FREIGHTLINER DEALERS WILL RE-FLASH THE SOFTWARE. OWNERS SHOULD FREIGHTLINER AT 1-800-547-0712 OR FOUR WINDS AT 1-574-266-1111.
