If its VSC and ABS light, speed sensor.
Unfortunately, Toyota give us no easy way to view body control module diagnostics.
Vehicle needs Solid axle Conversion
So when's that happening? Otherwise, the light will stay on FOREVER!
VSC, ABS, and TRC lights IIRC. Actually, could be the sensor or the wire. I know this from experience.If its VSC and ABS light, speed sensor.
Just have to hook it up to techstream and look up the codes. When my skid sensor wire broke it told me which wheel and where the problem was. Unfortunately it can't narrow it down to the wire or the sensor. I just started with the wire because it was the cheaper thing to replace and luckily it paid off.Unfortunately, Toyota give us no easy way to view body control module diagnostics.
Could also just be a muddy wheel speed sensor. Been out playing lately?

Give the whole backside of the wheel/rotor a good spray down. Should fix you right up.
No ABS light at all?
I still put my money on a wheel speed sensor
Why would you want to look at the Body Control Module? Wouldn't the Skid Control ECU be a better place to find things like ABS. VSC, and TRAC?
There used to be a way to initiate a self check mode with like a jumper wire and get 2 digit Toyota ABS DTCs that you could reference. I think some of the FSM still show the 2 digits codes as well as the C code lists... so I wonder if it still exists? I'll have to check for it later.
I had a wheel speed sensor go bad while changing UCAs. The factory wiring was crushed at the UCA attachment bracket from the factory (so when I relieved the stress to put on the new bracket, it stopped working). In my case it was a complete loss of connectivity and both the ABS and VSC lights came on. I simply tested each wire, since I knew that was most likely the issue.
Your problem may be the same since those wires are suspect after removing the stock UCAs, but I would think the ABS light would be on.
