This function is used to check the integrity of the split/ range cylinder's solenoid valves, and that the air cylinder's piston and position sensor are functional.
A noise should be heard when a valve is actuated. The cylinder stroke length values are displayed at the end of the test. The current value must be between the minimum and maximum values.
Possible faults:
Air faults: Dirt/oil in the air ducts, piston jamming in the cylinder, solenoid valve jamming or leakage from the air connections.
Mechanical faults: Worn shift levers, coupling sleeves or brass pins.
Test conditions:
Parking brake applied.
Air pressure in transmission between 550-1,000 kPa.
Engine off.
Battery voltage above 20 V.
Oil temperature in transmission above 15°C.
Procedure:
Select the function for the cylinder to be tested.
A dialogue box appears showing the test conditions. Check these.
Activate/deactivate the cylinder's solenoid valve; a noise should be heard. Press "OK".
The cylinder stroke length value is displayed.
The function is complete.
