Help clearing codes w/JB4 before service

oulaw · 07-11-2011, 12:02 AM

Plz don't flame me, I know that somewhere this has been posted I just can't find it with search and need to do this asap. I have the half engine light and am taking the car to my performance shop tommorrow to check out everything but want to clear the tuner codes and remove JB4 tonight so I can take it for service in after the shop rules out any other modifications they installed caused whatever has failed.

Hook it up to the laptop, that'd be easiest.

duh...thanks...I was looking through the can tool guide and trying to figure out another way to make sure they are all deleted. I can just download the interface and use it after I pull all the plastic out to remove the JB4.

I take it you don't have a BT Tool? Might be a stuipd question but that's what I have and had to clear codes with it before taking mine in...and I had to clear a few codes. I just had to make sure I cleared the shadow codes too....

Read the bit about reading/deleting codes on their site. You can do it through the steering wheel controls or with the laptop.
