Ignition overload protection

The ignition overload protection intermittently disconnects certain circuits in order to restrict the current being drawn from the battery while the starter motor is operating.

The position of the ignition switch is broadcast by the instrument cluster on the medium speed CAN bus.

The ignition overload protection relay which is integrated in the battery junction box is activated by the GEM if the message "ignition switch in position III" is received from the instrument cluster.

All of the electric consumers controlled by the ignition overload protection relay are then switched off.

The following consumers (among others) are controlled by the ignition overload protection relay:

• Fog lamps
• Windscreen/rear window wash/wipe systems
• Backup lamps
• Heated washer nozzles
• Heating blower motor
• Seat heating
