Note:

The terms "information sensor" and "cause of fault" in the trouble code table only provide a suggestion about the cause of the fault; i.e. if a trouble code is displayed, it is not necessarily the component listed in the trouble code table that is defective. Connection leads, plug connections and voltage supply must also be included in trouble-shooting.
