bigredhdt Posted August 10, 2020 Report Share Posted August 10, 2020 I check the diagnostic codes from time to time. On the engine, I see some that have inactive faults. I have seen some of the same codes for a while that are associated with the egr, but they have never been active when I look at them. When do you take action on the diagnostic codes? I just recently saw a single electrical fault on an injector, again not active. That one concerns me as it seems that might stand me somewhere.

Darryl&Rita Posted August 10, 2020 Report Share Posted August 10, 2020 Clear them all out, start worrying when they come back. May have been missed when repairs were made in the past.

bigredhdt Posted August 14, 2020 Author Report Share Posted August 14, 2020 When you are on the diagnostic menu where the codes are shown, hold down the enter button for couple of seconds. Quote Link to comment Share on other sites More sharing options...

Sparky242 Posted October 25, 2020 Report Share Posted October 25, 2020 does holding the enter button down work on Gen 1 trucks too? Quote 2000 Volvo VNL 610 2011 Cedar Creek 36RE Link to comment Share on other sites More sharing options...
lappir Posted October 26, 2020 Report Share Posted October 26, 2020 I think I have a gen one too it's a 2001. Not sure what you are asking, but if you want to find the diagnostic codes you can do so with the wiper stalk, the enter, escape and end up and down button. It's muscle memory for me so the actual instructions may differ. Hit escape. Toggle (using the button at the end of the stalk) through the menu to find the appropriate field. Hit the enter button, toggle again. find the code or error you wish to look at and hit enter. Write down the info (gibberish) and hopefully someone here is able to decode. Good Luck.

Sparky242 Posted October 27, 2020 Report Share Posted October 27, 2020 I have about 8 inactive codes and wanted to know if I can clear them myself or do I have to go to the dealer Quote 2000 Volvo VNL 610 2011 Cedar Creek 36RE Link to comment Share on other sites More sharing options...
lappir Posted October 27, 2020 Report Share Posted October 27, 2020 Me too and a couple that won't go away after the removal of one of the axles. As long as she starts and runs when I want her to and nothing else pops up new I have just ignored them. Got tired of asking what they were each time I visited a new service area and they had no idea. Volvo in Missouri, Volvo in Colorado, a couple places in Iowa and more in Florida. None had the answers.

Nigel Posted October 27, 2020 Report Share Posted October 27, 2020 (edited) On the gen 2 when you get the inactive code displayed hold down the enter button for a couple of seconds. If it asks for a PIN number try 0000 unless you know yours is different.

Sparky242 Posted October 27, 2020 Report Share Posted October 27, 2020 I tried that on my Gen 1 and it didn't work, I don't know if there is a way to do it or if that started with the Gen 2 trucks Thanks Stan Quote 2000 Volvo VNL 610 2011 Cedar Creek 36RE Link to comment Share on other sites More sharing options...
