Monitoring Function: Electrical diagnostics of ambient pressure sensor
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.
If the measured value from the ambient-pressure-sensor exceeds the upper calibration threshold, a short circuit to battery is detected and a maximum fault is set.
If the measured value from the ambient-pressure-sensor undershoots the lower threshold, a short circuit to ground is detected and a minimum fault is set.
