Notes for Service department

General notes 

After installation of the new ICM control unit, the diagnosis system must be used to start up the unit. Here, the following steps are carried out (depending on vehicle equipment):

• Adjustment of the sensor system integrated in the ICM
• Adjustment of the ride height sensors

Attention! 

The ICM control unit may only ever be removed or fitted when the battery is disconnected. The airbag control unit uses the sensor system in the ICM control unit to deploy the airbag. Otherwise there is a risk of unintentional airbag deployment!
