Abs And Traction Off Light (intermittant)

[07radoman]

Greetings all,

My 2002 Yukon XL (69K mls) has traction control and ABS. Last week the ABS light and the traction control light started coming on and off. Basically there does not seem to be a pattern and they do not stay on all the time, so kind of at a loss.

 

Any idea/suggestions?

 

Thanks in advance,

Mke
