Failure Code C Description
F01 : Inverter
Electrical
park brake
2
F01.10 (A)
1
ACEX : 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 and coil
If the wiring is correct, the problem is in the controller : Replace it.
2
ACEX : 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
ACEX : 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
ACEX : 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 controller : Replace it.
16
ACEX : 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
ACEX : internal Smart driver KO and COMBIAC : 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.
Inverter
slave
F01.11 (D)
1
COMBIACX : Failure in the high current hardware protection circuit.
Internal fault : Replace the inverter.
2
COMBIACX : When no current is applied to the traction motor, the current feedbacks are out of
permitted standby range.
Type of default not related to external components.
Cycle power to clear the fault. If the fault is not cleared, replace the controller.
4
COMBIACX : Driver of main contactor coil is damaged (not able to close).
Type of default not related to external components.
Cycle power to clear the fault. If the fault is not cleared, replace the controller.
8
COMBIACX : The driver of the electromechanical brake coil is not able to drive the load
Internal fault : Replace the controller.
16
COMBIACX : Pump current sensor out of range (at start-up or standby).
Internal fault : Replace the controller.
32
COMBIACX : At startup, the amplifiers voltage (used to measure the motor voltage) is too low
or too high ( < 2V or > 3V)
Internal fault : Replace the controller.
Wrong
controller
hardware F01.12 (D)
1 COMBIACX : Hardware version is not the expected one.
2 COMBIACX : Hardware version is not the expected one.
