What this code means

Before driving the LC coil, the controller checks if the contactor is stuck. The controller drives the bridge for some tens milliseconds, trying to discharge the capacitors bank. If they don’t discharge the fault condition is entered.

Applies to: ZAPI ACE0 / COMBIAC0 controller.

Possible causes / checks (from the source)

It is suggested to verify the power contacts of LC; to replace the LC is necessary.
