Monitoring Function: Monitoring during engine operation
WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2010 BMW M6, 2010 BMW M5, 2009 BMW M6, 2009 BMW M5, and 2008 BMW M6. However, it is still accessible from the selected car via links, so may be relevant.
As the ECU has its own time measurement, it can be used to verify the relative-time-measurement, whilst engine is in operation.
If the engine has been running for an operating-time time-ml, the relative-time-measurement has to have increased by the same amount of time since engine-start. If this is not the case, a fault will be set.
