1 | Connect the testing case | Necessary connections: Test connection circuit 1 (1), connection 21 Test connection circuit 2 (2), connection 22 Supply pressure test connection or tire filling connection (3) | |
| |||
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. | |||
