MOST control modules: Overtemperature cutout: Notes
WARNING: This page is about a different car, the 2013 BMW X5, 2012 BMW X5, and 2011 BMW X5. However, it is still accessible from the selected car via links, so may be relevant.
If a control unit becomes too hot, this control unit switches off for up to 10 minutes to protect the individual components against damage.
Furthermore, the entire MOST bus can switch off for \n10 minutes. After the control unit has cooled down, it is functional once again!
If the fault "Cutoff excess temperature" is stored in a MOST device, the control unit concerned and the headunit store the fault. The fault code entry from the headunit is evaluated in the test module.
The headunit is only displayed if it has switched itself off due to excess temperature.
