Ford E450 'Service Advance Trace' error
Almost every trip now, I get a 'Service Advance Trac' error on the dashboard of my Axis 25.6 E450 Ford chassis. The cruise control stops working. Usually after shutting off, it goes away for a while.
Has anybody else seen this / know the cause / gotten it fixed?
When I looked this up on the web, it appears to be due to stability - crosswind or loss of traction can cause it, but I am just cruising down the freeway. I have an appointment to have Ford look at it, but plan on doing some suspension upgrades soon as well, so wondering if I should wait for that first, and see if it goes away?
Any insight appreciated.
