For the past few weeks the car had been randomly dying, mostly when the car was warming up, but it always started right back up.

A couple days ago I went to start it in the morning and it turns over but won't start, also the message "No bus" is displayed on the odometer which Ive never seen before.

I verified all the fuses are ok, battery is charged & terminals are clean.

I tried doing the on,off,on,off,on ignition sequence to get any engine codes but that doesn't work either.

Any ideas what might be going on? Thanks.

 

"No bus" indicates a failure of the"data bus" which is how the computers in the car communicate with each other and with components in the car. Think of it as a thin wire that runs throughout the car like a telephone line. The computers send signals down the line and the signals are read by the appropriate device and are ignored by everything else. If the computers can't communicate with each other you're not going anywhere. You're going to need to get somebody competent with the right equipment to trace down the problem and fix it.
