I currently have the same issue on my 2008 Tundra. I have noticed that one of the 12v acces plugs don't work. The problem is intermittent and started when the air was damp or after it rained. Now the same lights are on, the 12v doesn't work and the remote door locks don't work. Toyota want to run a diagnostic check at $125 an hour. Did you solve your problem?
Have your truck scanned first to find out what is throwing on the check engine light. The VSC light comes on automatically with the CEL on Toyotas.
I'm having the same problem with my 08 tundra, ODB ll reading found no fault codes, truck is still lacking power and idles rough from time to time and dash lights continue to flash.... Not sure how to proceed without any codes to work with....
Truck has 165 000 km on it .....
Any help would be great!

You will need to hook a OBD II scanner to your vehicle to properly diagnose the problem you are having.
SOURCE: On my Toyota Sienna 2008, my check engine light,
On most Toyota's that are equipped with Cruise Control (Vehicle Speed Control or "VSC") and with Traction Control System (TCS or "Trac") all of these lights will come on at the same time if the Engine Control Module (ECM) determines that there is a fault in the engine management system that 1. Prevents the engine from being properly controlled. 2. Prevents the VSC from being properly controlled 3. Prevents the TCS from being properly controlled 4. Any combination of items 1,2, and 3.
Most of the time it is caused by a single fault in the engine management system. Fault codes are codes that are output by the ECM to let a diagnostician know which of the many systems, that are monitored by the ECM, is malfunctioning. To find out what the actual cause is, you must scan the ECM for fault codes then use this information to begin diagnosis of the system that the fault codes point to.
SOURCE: Toyota Avalon 2006, I ahve a VSC indicator light
VSC is Vehicle Skid Control. The system is usually on, but when you turn it off (on my mother's 01 Avalon, it's on the knee bolster, below and to the right of the steering column), the indicator comes on in the cluster to let you know it's turned off - it's just a reminder to you that you don't have that safety net activated. The way the car is set up, even if you turn it off, when you shut down the engine and then restart it later, the system is rearmed automatically.
What I'm thinking is, since you've obviously had the engine on and off and the VSC OFF and TC OFF warnings are still illuminated, you probably have a problem with either an ABS sensor, a yaw sensor, or something related to those, as those systems rely on a bunch of sensors to work. If they have failed, it should illuminate the check-engine light. Stop at Auto Zone or Advance Auto Parts and have them scan the car's computer (it's free). They'll give you a list of the fault codes that come up. If you post them up here, I can define them for you and help you solve the problem - just post them as a reply or follow-up on this posting.

I had the same problem. A computer check showed that the emission system was having difficulty. The catalytic converter had to be replaced. The car had under 80,000 miles on it so it was covered by a warranty (State law? Federal law?).
My battery was also dead. That was replaced free too. It had a 7 year warranty.
I do NOT purchase extended warranties.
