Failure Code C Description
F01 : Inverter
Low
Battery
F01.08 (A) 1
Low battery voltage (estimated value < 10%).
Check for damaged batteries, battery cables or connections.
Recharge batteries.
Measure batteries voltage and compare it with the value BATTERY VOLTAGE parameter in
the TESTER menu.
If they are different, adjust the value of the ADJUST BATTERY function.

F01.09 (A)
1
COMBIACX : Short circuit detected on electromechanical brake or main contactor output
(overcurrent).
Main contactor drive coil : Check connections and wiring for interruptions between controller
and coil.
Motor brake coil : Check connections and wiring for interruptions between controller coil.
If the wiring is correct, the problem is in the controller : Replace it.
2
COMBIACX : The driver of the electromechanical brake coil is shorted.
Check if there is a short or a low impedance pulldown between NEB CNA#4 and -BATT. The
driver circuit is damaged in the controller, which has to be replaced.
4
COMBIACX : The driver of the electromechanical brake is shorted to +Vbatt.
The output of the built in Smart Driver, which supplies the positive to the electromechanical
brake coil is high when the Tiller and the H&S switch are opened.
Check the harness, in order to verify if a positive is connected to the Smart driver output
CNB#1.
If, even disconnecting the wire from the connector pin, the output stays at high value, the
problem is inside the controller and the Smart Driver is probably shorted.
8
COMBIACX : A short circuit on the power outputs of the controller has been detected.
Check the EB driver output for a short circuit with +Vbatt.
If, even disconnecting the wire from the connector pin, the output stays at high value, the
problem is inside the controllerReplace it.
16
COMBIACX : Voltage on PEB present but not expected.
Check external wiring.
If the wiring is correct and no problem is found on the coil, replace the controller.
32
COMBIACX : internal Smart driver KO and ACEX : internal Smart driver is not KO (if both
signals are KO => failure F08.10).
Check the driver output for a short circuit with -Vbatt.
If, even disconnecting the wire from the connector pin, the output stays at low value, the
problem is inside the controller : Replace it.
