HW Fault

11/12/13

Hardware problem in the logic card

circuit for MC driver management.

This type of fault is not related to

external components, so, when

it is present it is necessary to

replace the ACE logic board.

HW Fault

01/02/03

Hardware problem in the logic

card circuit for power section

management.

This type of fault is not related to

external components, so, when

it is present it is necessary to

replace the ACE logic board.

Driver shorted

The driver of the main contactor coil

is shorted.

- Check if there is a short or a low

impedance pull-down between

NLC (CNA#16) and –BATT.

- The driver circuit is damaged in

the logic board, which has to be

replaced.

Contactor driver

The MC coil driver is not able to

drive the load. The device itself or

its driving circuit is damaged.

This type of fault is not related to

external components; replace the

ACE3 logic board.

MC Coil shor.

This alarm occurs when there

is a short circuit of the MC coils

connected to CNA#16 output.

After the overload condition has

been removed, the alarm exits

automatically by releasing and then

enabling a travel demand.

- The typical root cause for this

error code to be displayed is in

the harness or in the load coil. So

the very first check to carry out

concerns connections between

controller outputs and loads.

- In case no failures/problems

have been found externally, the

problem is in the controller, which

has to be replaced.

Positive LC open

Positive of MC is not connected to

the battery
