Hello,

The 'No Bus' message is the ECM sending a warning with regard to one of the computers in the vehicle not communication with the ECM.
It could be due to the faulty module, it could also be due to bad wiring harness.

Check the wirings, pay close attention to the harness under the driver side kick panel.

It is a good idea to scan for trouble codes.
This can point to the right direction with regards to diagnostic.

I have attached diagnostics procedure for the no bus code.


Please let me know of any questions.
Thank you.
