My ECM went out on my 2008 Corolla, a pretty common problem on these apparently. My ECM sku from factory was the 02Q92 ECM and I'm wondering if it can be replaced with a 02Q90 ECM. I've already tried replacing it with one from ebay but the sku was a K5 sku and not Q9. If anyone has done of these repairs before and has further knowledge I would appeciate the help!
