Valve diagnosis – Short circuit message disappears after
the problem has been remedied.
OPEN-LOOP detection only disappears once the error has
been remedied and the valve solenoid has switched again.
W
If during the voltage diagnosis all three messages
– Low voltage
– Voltage missing, and
– Short circuit
are reported for the actuated valves, check whether voltage
is supplied to the valve.
If a valve is actuated while there is no supply voltage, this will
generate a short circuit message.
