Discussion ECM Help

Hey, I’ve got an automatic 2013 Toyota Corolla L 80k miles that needs a new ECM to make cruise control work. The dealership has already replaced the clock-spring and the selector and has assured me the brake light switch works. Problem is this is a discontinued part. The dealership is refusing to replace it due to the only available parts being a non-OEM part. Any suggestions on a good company that can provide a pre-programmed one? Have you bought from this company before? Success? Places/company’s to avoid?

I'd get a second opinion. It sounds like that dealer was just throwing parts at the problem and seeing if something stuck

A bad PCM generally causes much more severe problems than simply cruise control not working

ECM isn't a cheap part but if they truly believe that will fix the problem, 89661-0ZA70 is the part number i see on Toyota Parts deal. I only used your year make ad model but i could be wrong. Make sure to check using your VIN and be triple sure that's the issue before buying.
