Got htis about a week ago. Service Traction control, Service ABS, Service ECS. all lit up at the same time. NO CEL. ligts went out about 30 secs. later. Then happened again this morning same senario. Again no CEL. '09 SS 112,000 miles. auto trans. Front Wheel bearings replaced at 90,000 miles . Thanks

 

How is the battery and charging system? Low battery voltage can cause havoc like this.

 

What were the driving conditions or scenario when these warnings lit up ?

FYI. I would pull the codes and check. Not all codes light up the CEL on the 1st occurrence. You may have a stored or pending code.

 

X2 on checking the battery voltage. I just went through something similar.

 

I don't know the history of the battery, So that would be a good place to start
I did check the codes this morning , there were no codes

 

does that mean immediately after the first start after sitting over night? Like a battery that got low enough from sitting that the starter dragged it down to less than 12 V?

 

Is it a group 90 battery?

 

yes, There is also a DIN (Euro) number I can't think of off hand.

 

First time 10 mins into my commute to work. this morning about 20 mins into my commute to work. First time ,driving through and intersection about 30 mph. This morning driving at about 60mph

 

What's interesting about that is a month or so ago I was getting "Check Charging System" and "Low Battery Mode" alerts at similar intervals. My battery was at 12.2 volts when I checked it. New battery, no more issues.

If it is your battery, watch what you buy. The one I replaced had one with an 18 month warranty. I lasted about 2 years.
