obd2 wont link to ABS.
my brake and abs light has been on (w/no abs braking). edge cs read a p0500 if i remember correctly rear speed sensor, so i put a knew one in and erased the code. the code will not come up again but the lights are still on. i do not know if i have abs braking yet. i bought an obd2 scanner nothing high end but it does read abs but it will not link to my abs system it says link error it does link for everything else but not the abs. anyone have any idea why?

Fuse box in the engine compartment abs fuse see if its poped
|
already did seems to be fine.
|
Next step would be to check all your wheel speed sensors but i would disconect bolth batterys for five minutes first if you havnt done that
|
I only have one speed sensor on the rear housing.I have already had the batteries disconnected for about 30 minutes to recalibrate the apps .if the abs module itself is bad would this not throw a code.

What happend when the abs light came on
---AutoMerged DoublePost--- I have seen where the reluctor ring in the diff was missing teeth and throw codes ---AutoMerged DoublePost--- And it could also be the copmuter just not turning the lights off |
It was on when I got the truck. Finally got sick of lookin at the lights and put a new sensor in.the old sensor looked fine though.

Oh welll i would check.all.the wheel speed sensors and pop that back diff cover off and take a look see it will also give you a good chance to see what needs replaced and all that good stuff a dirty wheel speed sensor will do this check you brake fluid make sure you lines look good make sure you power booster witch if its a 3500 with have hydro assist off the powerstearing take the conectors of the abs pump and clean them other then that theres not much else you can do just remeber the ABS light issnt just for abs its for the.entire brakeing system
|
Fluid level is good ii was gonna change diff fluid as preventative maintenance anyway so ill look around in there and I dont have four wheel abs so only one rear speed sensor. Thanks ill post any new info.
|
Right every dodge of this make only has one and it also for info for the speedo as well
