This function check the gear selector's solenoid valves, the air cylinder's piston, and position sensors.
When a valve is activated a sound should be heard from the transmission and status should become "Active". The values for the cylinder's shifting times and stroke are shown at the end of the test. The current value must be between the minimum and maximum values. When neutral gear is activated both 2nd gear and 3rd gear status becomes "Active".
Possible air malfunctions:
Malfunction of air supply to cylinder.
Dirt/oil in air channels.
Binding piston in cylinder.
Binding solenoid valve.
Leak in air connections.
Mechanical faults:
Worn brass pins, shift fork, or clutch sleeve.
Test conditions:
Parking brake applied.
Air pressure in transmission 650-1000 kPa.
Engine off.
Battery voltage above 20 V.
Procedure:
Select the function for the cylinder to be tested.
A dialogue box shows test conditions, press "OK".
Activate/Deactivate the cylinder's solenoid valve, a sound should be heard, press "OK".
A dialogue box shows shifting times, press "OK".
Values for the cylinder's shifting times are shown, check that they are within min. and max. values, press "OK".
A dialogue box shows stroke, press "OK".
Values for the cylinder's stroke are shown, check that they are within min. and max. values, press "OK".
The function is done.
If the function fails, check the test conditions and repair any faults.
