I've read alot on the abs light staying on (as mine does) Many people say the sensor could be dirty and to (a) take it out and clean it manually or (b) spray it down with a hose to lossen or remove any debris.
My problem is: I can't find the location of mine. From the pictures I've seen the sensors are buried deep in the wheel and I can't seem to find thyem by climbing underneath the rig.
Just how do you go about getting to them? Thanks

Does your 2014 , 42' Freightliner chassis have , air disc brakes on the front axle and drum brakes on the rear ? Or disc brakes all around?

disk on front and drum on rear

Other than saying the sensor wires; on front disc brakes; should be the only wiring going to the front spindles , I can't be more specific.

I'll be under my coach changing oil tomorrow ( weather permitting) and take photo of the rear sensor wiring.

Well after two days of rain , I finally got under the coach, for servicing.
That's the good for me news, the bad news is I couldn't get my camera in to take a picture of the rear ABS sensors.
I'll describe the location. The sensor wire drops from the inside of the frame rail to the air brake chamber, and is zip tied to " S " cam shaft housing then runs to the top of the differential housing axle tube, and into the backing plate.
Honestly , I think , the rear wheels would have to come off to access the sensor on my coach , if I'd removed the rear shocks , I may have been able to see the mount ; and maybe take a picture; rather than feel around for it.
I think your rear sensors may be mounted in the same place, and hope the access is easier.

Be aware that an ABS light can also indicate that your hubs/bearings are worn. Mine's in the shop now getting new bearings. Once the bearings wear, there is too much play and that sets off the ABS light.
