Accessing Addresses and Diagnostic Trouble Codes


Procedure for dealing with 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 current problem, 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:

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

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