Service Light on but no codes

[kvnkrk]

About a week ago I put a new battery in. After that I get my service engine light on only when I put it into gear from park. I took it to have the codes ran and nothing showed up. Anyone have any ideas what it could be before I start tracing down wires? Thanks this is my first post here but have found lots of useful info on here!

there is a code for sure, most likely who ever was reading codes did not know how to do it right, or the scanner was not capable to read transmission codes.

Welcome to AF kvnkrk !!

Which lights on the SES or SVS ??

If it's the SVS , when you put it into gear and it comes on, it's probley a high beam (DRL) lights coming on and the PCM noticing a lights burnt out.
Most code readers wont read these either.

Hope that helps and Keep us posted!
