Hi Guys,

basic question but where can I find the ECM!?

Need to find out the ECM number!

Thanks in advance!

passenger side floor board behind the kick panel. I think you have to pull up the front part of the door opening trim on the floor and pull the rubber weatherstrip up to expose all of the kick panel, then theres one of those stupid plastic pushpins that hold it in place.

Perfect, thanks!

IS see TMX2 so I assume that is the number.

Got confused with what an ECM actually was. Different name of an ECU right?

yes that sounds like the right code

ECM, ECU, PCM etc...all the same thing

The computer number should be on a sticker on the passenger door where it meets the body when closed (right beneath the door lock pin). No need to dive into the kick panel just for that.
