Any help would be much appriciated, thanks!

Now select a particular module (such as LDCM) by pressing the OPTION button to go forward or the TRIP button to go back.
Once a module is selected, the DTCs in that module can be displayed by pressing GAGES to move forward or FUEL to go back.
When a DTC is displayed that you want to get rid of ... press RESET
To exit the DTC mode on the DIC the E/M button
