Brief description
The IBS is a mechatronic component for monitoring the battery condition. The IBS is secured and connected to the negative terminal of the battery. The power supply for the IBS is fed across a separate cable. For data transmission, the IBS is connected to the DME (Digital Engine Electronics) or DDE (Digital Diesel Electronics) via the BSD (Bit-Serial Data) interface.

Notes for Service department
General information
Replacing the IBS.

The vehicle with the new IBS must be placed in the idle state for at least 3 hours: Only then can the new IBS determine the battery status.
The Check Control message is then no longer displayed if the battery is adequately charged and the correct battery charge state can be displayed.
