About once every month and half I get an unexplained service active handling message in the DIC. It stays on until I've shut the vehicle off a couple of times, then it's back to normal. The system functions perfectly as long as the message isn't displaying. The car only has 5500 miles on it.
What can I do next time this happens to figure out what's going on. It's bound to be a bad connection or something simple, because it's just too inconsistent and works perfect 90% of the time.
You need to display the stored DTC's on your DIC and post them here. There are dozens of possible causes for this, the codes will narrow it down to a very few possible causes.
There was a thread about this about a month back, cant find it now. someone had a write up with pics of loose terminals in the front wheel speed sensors. You could do a search for it, I had no luck finding it so far.
