Ignition
key data tapping on CBS vehicles
Situation:
In the
interests of simplifying service reception the current vehicle data (e.g. CBS
remaining values) are stored in the ignition key used last.
Note: The
ignition key is overwritten with the current data during driving at specific
intervals. As this writing process is repeated only after a defined distance,
the key data may differ at service reception slightly from the most up-to-date
vehicle data.
If a spare
key with an out of date data status is handed over to the Service Advisor, it
must be updated in the vehicle before service reception.
Procedure:
The process
for writing the current vehicle data to the ignition key can be activated
manually in the vehicle.
