Stored DTCs


NOTE: The stored DTCs cannot be erased.


If the current control module is to be installed for continued fault tracing, the order of current DTCs should be listed in order to be able to determine which alarm cause has arisen.

Bear in mind that during quality control of control modules and after the assembly of the alarm on the car, the alarm will be triggered via the different alarm inputs. These are also stored in memory.
