New here and looking for some help

Hey everybody, looking to get help and see if anyone has heard of my issue. Once this is resolved going to stick around and see what everyone does to their trucks! I have a black 2016 crewmax TRD 4x4 tundra which love btw. Anyways when I was towing a few months back, my ABS light and traction light came on and my speedometer would drop while was driving. Speedometer only does this when ABS light is on. Came on two times during that trip but just happened again the other day. Originally i chalked it up to an issue towing but nope, happpened again 3 months later. Light isnt coming back on after dealer said they were too packed to bring it in but have an appointment soon but wondering if anyone might know, appreciate all the insight, thanks.

Hopefully someone will have an answer

 

Does this only occur when trailer harness is connected?

I've noticed with mine that sometimes if I plug the 7 pin harness while truck is running the VSC and ABS lights turn on. Key cycle and they turn off.

 

First time was towing, not sure if was just on the road or after a fill up. Other 3 times have not been towing

 

Welcome to the party!!

Im sure someone will be along shortly to help out.

 

So you get speedo innaccurate, abs light, and traction control light. sounds to me like a wheel speed sensor. I suggest getting a scan if it persists.

Never hurts to clean power and grounds on the battery connections. Low voltage can cause all kinds of ghosts and doesn't cost you anything to try.

Not one of the 4 ABS sensors wire clipped or broken sensor???

 

No, checked all the tires underneath. No wires looked messed up, everything looks good underneath. Dealer said it was going to run tests on each wheel checking the magnet distance on all tires.

 

Welcome. I'm guessing ABS sensor.

 

Heard it might be two different things but wont know until dealer takes it, should be warranty work

As others have mentioned I'm going with an ABS sensor going bad.

Only real way to know what The Faults Are is to hook up a scanner.... I'm guessing AutoZone should be able to hook up to the brake module.

 

So its been forever since the light came on but it popped up after i went through a car wash. Washed it, went shopping then came on after start up

 

Unfortunately i didn't get to scan it and haven't seen it since but next time yes scanning for sure but have a few days until dealer looks at it
