DTC code U0002-88

[Gammellicious]

Hello I'm new to the forum and new to dodge journeys. I recently purchased a 2011 3.6 AWD journey and I'm having brake issues. The driver side front brake keeps dragging. Now my traction control light is on and it's in limp mode. I plugged my scanner in and got a U0002-88 for can bus short for the ABS module. Any ideas where I should begin looking?

as far as the brake dragging check the rubber hose that connects to the caliper has been reported they can build up rust that holds the hose to the brace builds up under the bracket cutting off pressure to the unit,,,also have you removed the slide pins in the caliper to make sure they are clean and greased properly,or you might just need to replace the caliper as well.....fixing this first might solve your other problem if not I would take that to the dealership

You need a bi-directional scan tool. Capable of communicating with all of the electronic modules.
