Diagnostic Trouble Codes (DTCs)
can be detected from other control
modules like e.g. connector

completion the DTC memories of all
control modules must be checked
and erased. To do this:

its identification the number of stored
Diagnostic Trouble Codes (DTCs)
appears on the display or "No fault
detected".

Any system Diagnostic Trouble

displayed one after the other and
