- The EB driver is shorted.
- The microcontroller detects
a mismatch between the valve
setpoint and the feedback at the EB
output.
- Check if there is a short or a
low impedance path between the
negative coil terminal and -BATT.
- Check if the voltage applied is in
accordance with the parameters
set.
- If the problem is not solved,
replace the controller.

its driving circuit is damaged.
This type of fault is not related to
external components. Replace the
logic board.

- Check the EB coil.
- Check the wiring.
- If the problem is not solved,
replace the logic board.
221 HANDBRAKE Handbrake input is active.
- Check that handbrake is not
active by mistake.
