What this code means

The built in smart driver is open, not able to provide the electro mechanic brake positive.

Applies to: ZAPI ACE0 / COMBIAC0 controller.

Possible causes / checks (from the source)

A) It is suggested to check the harness, in order to verify if the Smart driver output CNA#2 is shorted to –Batt. B) If, even disconnecting the wire from the connector pin, the output stays at low value, the problem is inside the controller and the Smart Driver is probably damaged.
