System Errors

The controller will continuously check for errors; when an error is detected it will be reported to
the user by a flashing sequence of the external LED, as well as a corresponding red flashing
sequence of the status LED. Damage to vehicle or engine may occur if these faults are not
resolved immediately. The water-injection system may not operate properly or at all while an
error condition exists. Please refer to the table below for further information.
