So I recently hit a deer with my 08 Tundra 5.7 and its mostly just cosmetic damage to the front bumper which got destroyed. I was driving and all of the sudden all of my lights starts flashing, vsc 4hi 4lo traction control brakes abs, computer was going nuts. It drove fine so I got to work, turned it off for a bit, turned it back on and just the ABS remained. I am sure this is all just electrical issues (great) and I noticed this frayed and damaged wire hanging from my front bumper, exposed from the missing piece of said bumper. What is this wire exactly and would it being frayed like that cause electrical issues like I explained?

And if not, any idea what to check for the cause of my ABS light being stuck on and the other lights going nuts?

Do you have sonar sensors in your front bumper? Thats what it looks like to me based on the location. That is the front left corner correct? And yes, a short can cause all kinds of problems which in this case you probably threw a code. Tape up the wire so it stops shorting out, and get the code read and removed, or unplug the battery to clear the code and see if it comes back on again.

No sonar sensors, but it's helpful to me that you say a short could cause codes like that even from a seemingly unrelated wire. I am going to unplug the battery and see if that clears everything for now.

Just had the battery disconnected for an hour or so and I taped up those wires so they weren't exposed. Unfortunately the ABS and engine light still remain. I suppose my next step would be reading the codes.

Hello there I'm having the same problem any pointers would be greatly appreciated thank you
I went and wrapped up the exposed wires I had and secured them better and the flashing lights went away and I disconnected my battery for good measure and the abs light remained but I went to drive and it went away on its own.. so I'm guessin all my problems were related to electrical shorting out. First things first try and find damaged wiring under your truck and then disconnect the battery to reset the computer

Mice maybe. This time of year you see threads pop up where someone has weird electrical problems because the little bastards like to make nests inside the engine compartment. That being said if you have lights lit up on your dash get them read first to see what the actual code is, then you can start to trouble shoot the cause.

Yup I bought myself a obd2 reader off Amazon I figure that's more useful for diagnosing than any amount of explaining I could do without codes. Will have to see what it says.

  1. My friend tried running a scanner on it and there's no communication through the obd
Thats unfortunate. I would check for fuses and then check to see if the physical port is damaged, I'm sure there's diagrams for our obd2 connector. May need a multimeter to check impedence and such for proper ground, beyond that it could be a complete computer issue/wiring.

We checked all the fuses and they are good, I forgot to mention to you that it happens here and there and then goes away and starts working properly

Are you sure your friends scanner works on Toyota's? I dont know anything about the code readers, just seems strange that it gets nothing at all through the port. Maybe go to a local automotive store that has code readers. I heard some of those places will read your codes for free.

It sounds like it's an issue with one of your 02 sensors. That's what happened when one of my 02 sensors was sorry in my 04 Sequoia
