The system switches off automatically if a critical error is detected. Activating the control
unit is only possible by repeatedly switching on the supply voltage.
Only the error occurring last is issued if several errors occur at the same time. We there-
fore recommend troubleshooting one error after another until the diagnosis indicator light
no longer flashes.
