Just starting today I have flashing messages on 2009 2500HD 4x4 gas.
They scroll between:
“Service traction control”
“Service trailer brake system”
Also, the traction control symbol and the ABS symbol are staying lit.
It drives and brakes fine.
1) what the heck is this?
2) will it hurt to drive until I have time to get it fixed?
(We are in the midst of lawn mowing 25 accounts and it will be several days before I can really afford to be without. We do pull a light trailer for mowing, but only single axle, do no trailer brakes.)
