so my my cel came on two weeks ago and found it to be 9318 on the dec. the car happened to be in the shop the next day so they put a new battery in it and resetted at no charge to me. The light went away. I was driving today (in a lot of rain, anyone in Vancouver will know what I mean) and the CEL came on. The car didn't drive any differently. I turned it off and put it in diagnostic mode expecting to see 9318 again, but it came as none. Now I don't know what other codes or what to look for to figure out what it is. Or should I just disconnect the negative and reset it, to see if it goes away. Any assistance would be great. Thanks in advance.
