The new SP Diagnostics SBC tool has been created to allow you to service and replace brake pads and components used in the SBC systems which have been fitted on a number of Mercedes vehicles (W211 and R230) since MY2003.
The SBC system incorporates various systems which have previously been separate, ABS, ASR, BAS, ESP and ETS. The SBC system can be "woken up" by opening a door, operating the central locking, depressing the brakes, turning on the ignition or operating the park brake. When this occurs the system runs pre-checks which include a pressurisation of the braking system. If the brakes are either being worked on or are dismantled when these pre-checks occur it can lead to personal injury or damage to parts of the caliper and pad assembly. The SBC tool allows you to disable the system during service and repair work, thus allowing a safer working environment for the user.
