rs6er Posted December 3, 2014 Share Posted December 3, 2014 Is there a way to clear all of the codes by disconnecting the battery? Link to comment Share on other sites More sharing options...
mikeydrives1 Posted December 3, 2014 Share Posted December 3, 2014 Yes, but this will reset clocks and radio settings. Its far wiser to invest in a cheap code scanner that can tell you what the code is, as well as perform an ECU reset to clear the code without having to go through all of that trouble.

rs6er Posted December 3, 2014 Author Share Posted December 3, 2014 If I don't mind the trouble, how do I do it without a scanner? Just disconnect the battery or do I have to do something else? Link to comment Share on other sites More sharing options...
turbolgt Posted December 3, 2014 Share Posted December 3, 2014 I believe all 05+ lgts have a built in code reader from what I have read on these forums. Link to comment Share on other sites More sharing options...

R15 Posted December 3, 2014 Share Posted December 3, 2014 Disconnecting the battery doesn't "clear" codes anymore then it "clears" your clock or fuel trims, they're just no longer stored in active memory. They'll be back once you complete the open/closed loop (a few times). Torque + Seagate iCar, $20 for OBD2 code retrieval and removal with added real -time monitoring of any data that your car has a sender for on your phone. FWIW I wouldn't let any codes ride on these cars that I didn't cause through mods. Link to comment Share on other sites More sharing options...
turboSz Posted December 4, 2014 Share Posted December 4, 2014 FWIW I wouldn't let any codes ride on these cars that I didn't cause through mods. One of the truest statements I have ever read I've let a couple CEL's run a bit longer than I should and boy, was that a mistake! Link to comment Share on other sites More sharing options...
Max Capacity Posted December 4, 2014 Share Posted December 4, 2014 You can also reset the CEL by turning the engine off/on four times. When you get a overboost CEL you can push in the clutch and do the off/on 4 times and the CEL is gone. Had to do that once in my Spec after I put the DP on. Haven't had a CEL since. Back in the early day's with my wagon with a manual boost controller it would happen a lot. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it. Engine Build - Click Here Link to comment Share on other sites More sharing options...
