Checking pressure sensors
This function is used to check the value of the pressure sensor connected to ECS.
A pressure gauge should be connected to the pressure sensor that is to be tested.
Note:
The test socket is not always near the pressure sensor. Follow the air hoses from the pressure sensor to locate the correct test socket.
Test conditions:
The wheels must be chocked.
Parking brake released.
Working pressure in air system.
Battery voltage above 20V.
Check that the bellows are intact.
Procedure:
Start the function.
Choose the axle to be raised or lowered.
Compare the pressure on the pressure gauge with the pressure on the screen.
Repeat the test for each valve.
The function is done.
If the function fails, check the test conditions and repair any faults.
