If a control module becomes too hot, this control module switches off for up to 10 minutes to protect the individual components against damage.
Furthermore, the entire MOST bus can switch off for 10 minutes. After the control module has cooled down, it regains function!
If the fault ”Cutoff excess temperature” is stored in a MOST control module, the control module concerned and the head unit store the fault. The fault memory entry from the head unit is evaluated in the test module.
The head unit is only displayed if it has switched itself off due to excess temperature.
The Top HiFi amplifier can only disable its own functions at high temperatures. If the customer is currently listening to music, the following fault pattern results:
The Top HiFi amplifier does not make a fault memory entry. The MOST framework remains functional. After the control module has cooled down, the Top HiFi amplifier regains function!
