Hello,

The instrument cluster and the Power-train Control Module [PCM] or "computer" are a matched set in these cars and cannot be interchanged. In the diagrams down below I have included a description of how the Passive Anti Theft System [PATS] works on your vehicle. Please go through this guide and get back to us with how everything works out.

Thanks,
Alex

Hello, most shops these days have scan tools capable of reprogramming the immobilizer unit. Most likely that's the issue if the car ran okay before the change over. The security systems can be tricky when changing parts around. The ECM needs to programmed to the immobilizer.
