So ive asked a few ?'s on my new toy, sorry car & have gotten some decent feedback. On that note here's another one, 53k on her & was out driving 2day & all of a sudden i here a ding ! I look @ the dash & it went haywire for a quick second. Tack, speedometer, fuel & every message appeared in the message screen. Any ideas ? 2day was the first-time problem & it happened about 1/2 a dozen times but nothing was affected by this cluster spike. Any help or advice would greatly appreciated. Thanks in advance Shane G.

Your losing GMLan communications with the BCM, TCM and ECM. Try disconnecting the 2 blue connectors on the BCM and reconnecting to clean them a bit.

I'll give that a try but i just had both of them & battery unhooked while i installed a new upstream o2 & performance maf sensor. The problem did occur after that do maybe one's not seated properly. I heard some models have had a reflash recall on the computer for updates, any ideas what models & yrs ?

You may also want to change the fuse in the upper left hand corner. It is called ECM/TCM but should be called GMLan
