Check Control: Notes

Until now, the Check Control has been a reporting system for vehicle faults. For the E65, the scope of functions has been extended considerably. It now also displays operating statuses and provides detailed instructions. This provides the driver with valuable assistance, enabling the appropriate reactions in the event of a system failure or fault, despite the increasing complexity of the vehicle electronics.

In the E65, the number and information content of the messages have increased considerably in comparison to the E38:

• Most CC messages contain a unique instruction, telling the driver what to do.
• The message texts are more detailed (40 characters instead of 20 in the E38).
• Parallel to the CC message, the On-Board data menu of the Control Display contains more detailed information (up to 170 characters!) regarding the current message. In the case of particularly important messages, this appears automatically.
• The combination of text and graphic ensures faster assimilation of the information on the part of the driver.
• The number of warning indicator lamps in the instrument cluster has been drastically reduced; many of them have been replaced by more informative CC messages with variable indicator lamps. Warning lamps are now only used where this is legally required.
• The Check Control is easy to expand, as the evaluation of the message conditions for the individual functions and systems has been shifted to the relevant control unit in each case.
• The coolant-temperature gauge in the E65 is no longer a separate instrument, but a function of the Check Control. It is only displayed when required.
