Deactivation, excess temperature

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 ā€¯Deactivation, excess temperatureā€¯ is stored in a MOST control module, the control module concerned and the Multi Audio System Controller (or Car Communication Computer) also store the fault. The fault in the Multi Audio System Controller (or Car Communication Computer) is evaluated in the test module.

The Multi Audio System Controller (or Car Communication Computer) is only displayed if it has switched itself off due to excess temperature.

Top HiFi amplifier: Detection of 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!
