I have a ScanGauge II on my Suburban and it's hooked up all the time. It has yet to throw a code when the Suburban is acting up.

Most of these problems all started to occur at about the same time.

I guess it could be a ground problem. I think I'll pull the battery, disconnect and inspect the ECM and speedometer cluster and then reconnect. Hopefully I just have a bad connection somewhere and this solves the problem.

This problem is starting to bother my wife to the point that she wants me to trade the Suburban in for a new truck. It makes her uncomfortable when we are on a trip, towing our travel trailer and the dashboard is lighting up like a pinball machine!

Thank goodness for the ScanGauge II and the GPS. The ScanGauge II tells me how much fuel I have remaining and the GPS tells me an accurate speed.

Keep the suggestions coming. I really need your help. I love my Suburban and don't want to trade it in.

On a couple of occasions the fuel gauge registers empty and the low fuel light come on with ¼ to ½ tank of gas in the tank. The ABS and Brake dash lights occasionally illuminate and usually stay on until the ignition is turned off (even on short trips).
