Calling up Addresses and Diagnostic Trouble Codes

Every control unit monitors certain electrical circuits within the network of circuits for which it is responsible. The unit then stores the relevant diagnostic trouble code if there is a malfunction (error) or if the operator makes a mistake. However, not all of the diagnostic trouble codes indicate a problem occurring at this very moment, since most of the circuits are monitored only at the actual moment of activation or when they are actually activated (switched on). To make sure that the diagnostic trouble code you are troubleshooting is "active", you should proceed as follows:

• Call up diagnostic trouble codes.
• Note and clear the diagnostic trouble code(s).
• Activate the circuit affected (functional check).
• Call up the diagnostic trouble codes again and process them.

If it is not possible to (re-)produce a relevant diagnostic trouble code by means of a functional check and the problem is still present in the circuit, deal with the codes you noted earlier.
