Mercedes-Benz W211, R230 manual Deactivation

Deactivation

SBC must be deactivated with SDS before any work is performed on the system. This will prevent the pre-drive check from being automatically performed which could cause injury.

Deactivating the system will:

• empty the pressure reservoir

(a lower pressure with no volume may be retained)

• prevent the charge pump from operating

•Note: the warning buzzer is deactivated when accessing SBC with the SDS.
