Mine did exactly that (slip light) but as soon as I drove around for a while it went out. I Still should do the air idle volume relearn...don’t have a scan tool so may have to get my handy stopwatch readyIf you want to do an idle air volume relearn, it's not done by disconnecting the battery cables. It's a learned function and leaving the battery disconnected will only erase the stored memory. It's not the same as erasing the self-learning memory of the ECM. To do the idle air volume relearn, you need to have a scan tool that has that capability or go through the complicated manual procedure listed above. Also, disconnecting the battery for a long time can also erase the steering wheel position memory for the VDC system, which will result in setting a C-code and turning on the VDC/SLIP warning lights. Sometime, driving in a straight line will correct it, but if not, that, too, will have to be re-learned with a capable scan tool.
