Can some one please help me??

CK. all your brake drums looking for a wheel seal leaking, shine strong light into the holes in brake backing plate to ck for oil running into the brake drum, that can set off a set of ck. abs. lights??

 

The Cascadias I've driven would throw a CEL at any given time. It might go off or stay on for awhile. truck would run fine. Same with the ABS lights. I got used to the dash looking like a christmas tree.

 

On the bright side,,,, tis the season for Christmas trees!

Sorry, couldn't resist the irony

 

I don't know about truck ABS but when cars have issues most of the time the abs wheel sensor has brake dust and grease covering it making the sensor malfunction. Simply cleaning the sensor makes the abs light go out. I would assume on these trucks abs systems operate in the same way.

 

Sounds to me like you've got some voltage regulation problems or a wiring harness somewhere is working loose. Do your headlights seem to burn normally both high and low? Do you have an inverter? Is it off?

Best thing to do for such a problematic truck is ship all your valuables home, park in a back, empty corner, grab your cell phone and purse, light a cigarette, place on top of your quilt, then go have dinner inside

 

No sense getting Daqed. Cigarette too obvious, and freightliners usually don't need the help

 

Until you get it back to a shop, use electrical tape to cover the lights on the dash.
(Before everyone goes nuts with this advise......the driver has had problems with the tractor, driver is inexperienced. Obviously the tractor still preforms it's job, so cover the lights until it gets to a shop)
