Solenoid valve test "with roller dynamometer"
Solenoid valve test "without roller dynamometer"
The solenoid valve test is used to test the electrical and hydraulic operation of the ABS solenoid valves and test for correct assignment to the relevant wheel.
Only test on roller dynamometer or with wheels jacked up!
When testing on the roller dynamometer, build up a braking force of 1 kN using the brake pedal, otherwise the roller dynamometer will automatically switch off.
After one of the functions has been selected in the menu, the progress of the test which is the same for all ABS solenoid valves is shown in the HHT display.
Solenoid valve test menu:
2(3).1 FL solenoid valve
2(3).2 FR solenoid valve
2(3).3 RR solenoid valve
2(3).4 RL solenoid valve
A second operator is required to support the pedal.
