Hi all,
Best holiday wishes to everyone. Great site.
Brand new member. Need info badly. This afternoon while changing tire, truck slid off of jack and landed on rim. Painful to watch. Jack became wedged and used another jack to rescue. Everything underneath looks fine but now have four distinct dash warning lights / messages. ABS light, ESP indicator light (sliding car), low tire pressure light and in the center of dash the SER 4WD / ESP BAS warning is given. What have I done to my truck?
Would greatly appreciate any information.

Probably broke the wheel sensor or unplugged/cut the wire to it. All those lights are an indication it can't read that wheel sensor.

Thanks very much for the reply Netmann. Major / expensive deal to replace ??

I second that^ Look around at the wires gong to the wheel, and possibly the sensor itself is maybe damaged.... USE TWO JACKS AND A JACK STAND!

Damn good advice Snrusnak . Never had one drop off the jack on me. Level ground. Everything looked great. Right up until it started to move. How hard to remove and replace a sensor ??

 

[GTyankee]

The sensors are easy to replace, the bad part is that i think they come in sets of 4
Just let the air out of tire & remove it similar to a valve stem

I would take it to a tire shop & get their opinion, an auto wrecking yard may be the place to get a sensor ??
any gen 4 ram will do, maybe even older, just has to be the correct radio frequency

^I haven't ever looked at them on these trucks as I haven't had to yet so I'm not much help there, but it has to be something with the wires or the sensor...

 

[snrusnak]

Just FYI GTYankee is talking about the TPMS(tire pressure monitor sensor) which is inside the tire, and is wireless, I was more talking about the wheels sensor which would be hardwired and have a sensor that reads the wheel speed. Both would be worth looking at.

I had the same thing happen to a buddy and it was the wheel speed sensor. If the truck cant see the speed sensor it will freak out. Im guessing your cruise control stops working too. Shouldnt be too bad to fix.

 

[Netman66]

Sorry I'm late on this.

I was referring to the wheel sensor for the ABS/ESP - not the TPMS (pressure sensor in the tires). Sorry about any confusion that generated.

They are not difficult to change on the front. On the rear, it may be in the differential case (pumpkin) and pray it isn't the ring inside the axle! If it's just the wire/sensor, it isn't bad.

Thanks for all the info guys. CombatMedic - you're right on the money: no cruise control. Had tire patched today. One lousy little roofing nail. One bad jacking job. One big headache. Live and learn. Thanks again guys and have a happy holiday.

Wheel Speed Sensor it is. Hope the stealership doesnt screw ya!

Hello again guys. Thanks again for the previous info. Quick question. Everything I read says the Wheel Speed Sensor is mounted on the differential. I can't see anything there but have a small wire harness going to each rear wheel, right near the Emergency brake cable. Is this the WSS or something different ?? Could these wires be part of the Low Tire Pressure receiving system ?? Main reason I ask is, really the only area that received any abuse from the fall, which was only about 10 inches or so, was the inside of the wheel - right around the shock mount, etc. This wire and adjoining mount to the inside of the "plate" definitely took some shock. How could a "smallish" fall harm something way back at the differential ?? Thanks again fellas.

The Tire Pressure Sensors are wireless. Im guessing that the wire is for the WSS. Ive seen them in other trucks and the WSS is small and if it takes a :box2: they will stroke out.

Thanks a bunch, CombatMedic. I'll unbolt and pull this assembly from the rear wheel plate and see what I can make of it. Surely appreciate your info.

 

[NorthoftheBorder]

Thanks a bunch CombatMedic. I'll try unclipping the harness assembly and unbolt the insert part from the wheel plate and see what I can see. Surely appreciate your help.
