What this code means

A) The EVP driver is shorted. B) The microcontroller detects a mismatch between the valve set-point and the diver voltage measured on the LOWER EVP1 output.

Applies to: ZAPI ACE0 / COMBIAC0 controller.

Possible causes / checks (from the source)

Check if there is a short or a low impedance between the negative of the coil and -BATT. Otherwise the driver circuit is damaged and the controller must be replaced.
