"Pulling the network down" is anything that keeps the network from communicating. An open or short or a module that has something causing it to lose connection to the network. This would be intermittent due to cold solder joint, ground, loose wire or connection at a splice or block. You discovered what is pulling your network down when you seen the cluster working and you had communication with the network then the cluster not working and no communication. It's hitting you in the head so hard you can;t see it.

grcauto, You are amazing and I admire your conviction and knowledge that problem is in the instrument cluster. As you suggested I pulled the cluster out but there were only two plugs attached behind it and not individual plugs for each measurement gauge. So I pulled one plug out and problem stays. Put this plug back and pulled the 2nd one out and problem stays. Next I disassembled the cluster and looked at the stepper motor's 4 soldered contacts on PCB coming out of heat gauge. Heat gauge needle was the only needle slightly flickering and rests were solid zero when cluster not working. Thinking this shaking is due to the open ground either by open capacitor or resistor, I used a 110 ohms resistor and soldered across it to provide a safe path to the ground. Assembled the cluster back and put back in the car. I started the car and found Fuel and Tachometer needle started working right away and speed and heat while driving. This shows problem is fixed without spending a dime. I like to thank especially grqauto and all the others members who helped me in solving this problem. Thank you again
