I have an 09 Pontiac G6 3.5 L V6, tonight when I started driving the car my CEL, TCL, and Security light all came on. Error started flashing on my Odometer and my radio/information display became glitchy. All of the gauges on my dashboard from the speedometer to the gas to the temp started going haywire. I got home but my car certainly felt off as well. Is this a bad BCM?
We checked the battery. There was slight corrosion on the N/P connectors. But other than that nothing. We also checked the TCM the BCM. Reset the computer only to have it happen again today.
There has been problems where the negative cable grounds, corrosion.
