up to 09/2006: Fault display

The LC matrix for the LCD display lights up completely if a system fault develops. A fault is displayed under the following conditions:

• If the vehicle is highly magnetized (2, 200-2, 500 milligauss), the measuring range of the magnetic field sensor will be exceeded.
• If a fault develops in the circuitry of the magnetic field sensor.

Gauss is the unit of measurement for magnetic flux density.
