We need to check voltage on pin 6 and 14 of the DLC and see what they are. Then we need to check voltage on pin 16. You should have 12 volts on pin 16 and then your should have around 2.5 volts on 6 and 14.
In order to communicate with the scan tool and PCM you need your CAN bus to be intact. Here is a guide that talks about this:
If the voltage is not correct then there is something causing the network to be corrupt so we would need to figure out what that is.
Here is a guide that will help with those voltage readings:
Here are the wiring diagrams for the DLC that we need to use. Let us know what questions you have. Thanks
