2	Fill the brake system with compressed air until the pressure controller switch off
3	Switch ignition on
4	Instrument (INS) displays the measured values (MW) 1 and 2
5	Compare the measured values (MW) listed with the pressure gauges indication	 From 970 MW to 1070 corresponds to 9.7 to 10.7bar on the pressure gauges indication. If the values matches, the supply pressure sensor of brake circuit 1 and 2 (B71) is in order. The test is closed.
		In case of diverging values, perform the following tests: 
		Check harness in the passage for short-circuit. If necessary, fix the defect.
		Check the supply pressure sensor of brake circuit 1 and 2 (B71) on the four-circuit protection valve with the test adapter.	AR42.60-B-0080-01TA
