what were the code numbers you gave me code c1336 This means there is a zero point calibration code unfone. So you need a zero point calibration needs to be reset with a scan tool.

Both the Check Engine light and the Slip Indicator light on my 2009 Tacoma came on for no apparent reason. The truck has only 34,000 miles on it. After reading blogs on the internet by people having the same problem with their Tacoma, I tried the easiest potential fix first: just tighten the gas cap until it "clicks" and disconnect the positive cable from the battery for about 20 minutes. Bingo, that fixed the problem! Those simple actions saved me a trip to the Toyota dealer and who knows how much in charges by their service department.
Replace the antifreeze with Toyota Lifetime, change the diff fluid, some dealers recommend tranny flush at 100K, change the serpentine belt. Be prepared, you have WS tranny fluid, the flush is $200+
You need a scanner to pull out the engine light codes.
Use a shopu manual to aid you with the diagnosis and repair.
The slip indicator and vsc light being on means these systems are not working. Once you pull the codes and do the repair and erase the codes the lights will go off.
There will be a code in there for the misfiring.
Good luck and keep me posted.
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.
The Malfunction Indicator Lamp or MIL (Also called the check engine light or service engine soon light) comes on when the on board computer detects an issue with the operation of the engine or transmission.
The best thing to do is to take the vehicle to an auto parts store like Autozone and have them hook up their scan tool to the vehicle and read the code. They can read it, tell you what it is and also tell you what the code means.
If it is pointing to a faulty component or sensor and you replace or repair the component the the light will go off on its own after the computer sees that the malfunction is no longer present.
You can have the code cleared, but if whatever caused the light to come on in the first place is not addressed then it will just come back on eventually.
A few days ago I started the Cruiser and had 4 indicators stay lit.
They were the CHECK ENGINE...SLIP INDICATOR..VSC TRAC..VSC OFF.
Didnt noticed any change in driving and 4-wheel drive is still working.
I removed the negative cable from the battery and the same indicator lights have NOT
come back. Everything is back to normal as far as warning lights go.
Should I take it in to the service center and have it checked.
Or should I wait to take it in, if it does it again?
