Whenever the check engine light comes on, the computer stores the code the made it come on, so take it to a mechanic that can read the codes, or you can get a code reader for about $150

The dealer will hook up to diag and read error code from lights and fix. It could be anything from o2 sensor to short. Other light is on because it is on.(VSC)

There are LOTS of possible problems. Whenever there's ANYTHING wrong with the brake/trac/vsc systems, all three of these lights come on.

You can try clearing the codes by parking on a level spot, e-brake off, wheels straight, engine off, and disconnect your battery for 2-3 minutes.

Possibilities:

-sensor problem (there are about 15 different sensors that recalibrate themselves every time the truck is started)

-alignment problem

-brake/ABS system problem (even if the brake light isn't on) check brake & power steering fluid.

You can get a factory service manual (or go to tis.toyota.com and buy a subscription) to troubleshoot yourself, or find a good dealer or competent independent tech.

They MAY tell you that the computers need to be replaced, which will be thousands of dollars. I would try some of the cheaper solutions first.
