There are a number of things that can cause this, but we need to start by checking to see if the theft light remains on.

If it does, then we need to deactivate the system.

If you are not able to deactivate the theft system, then we need to figure out why the scan tool is not connecting.

If it is telling you to check the connection, then that means it is getting power but not able to connect to the modules.

So, this means we need to check the voltage on pin 16 and ground on pin 4 and 5.

Then we need to check the resistance of the wire from pin 9 to the DME on pin 10. You should have less than a half ohm on this wire.

Please see the wiring diagrams below and let us know what you find with this.
