InspectionCâu 41 / 60
What does it mean if the low-pressure warning stays on after you start building air pressure?
a.The brakes are fully adjusted
b.The parking brake is released
c.The system pressure is still too low, or the warning device is faulty
d.The compressor has cut out normally
Giải thích
The low-pressure warning should turn off once air pressure rises above about 60 psi. If it stays on, either the system has not yet built enough pressure or the warning device or gauge is malfunctioning. You should not drive until the cause is found and pressure is normal.
