Hi!

Turn ignition on, don’t start the engine, just ignition on, press the odometer button in and hold in. (make sure your odometer is reading the actual mileage, not the trip meter)/ Turn ignition off while still holding odometer button in. Turn ignition on again, still holding odometer button in, the odometer reading will display short dashed lines like this: ------. Keep holding the button in. Watch as the dashed lines begin to decrease and finally disappear. The odometer then should return to reading out the mileage again, and the maintenance light will not come back on. At least not till you reach another 5000 miles. It is designed to come on and bug you as you reach 5000 mile intervals. Resetting this maintenance light will in no way shape or form hurt your Toyota. This "maintenance" light is a clever way to get you to see the Toyota service department.

If still the problem persists then perform the following procedure:

The O2 Sensor may not be securely attached. Check it and plug it all the way in.

Re-calibrate the zero point calibration for the yaw rate and deceleration sensors.

The calibration, by the way, is simply a matter of telling the 4Runner VSC/TRAC computer "your yaw rate and deceleration rate are currently zero" and to save the associated values. Then the output from the sensors can be interpreted correctly.

Please do accept this solution and revert for further assistance if needed.


Thanks

Rylee

Hello sir , we have read your problem at fixya. but i am unable to understand your problem clearly and it will be better if you give a brief description so that we get it solved quickly.
any way from your question i was able to understand that the maintenance light is on, probably it is not switching off.

To start troubleshooting this problem:

  • Turn the key to the on position (do not start engine)
  • Inspect the system fuse located in the fuse panel and replace if needed. If you cannot find the location of the maintainence light fuse consult your owner's manual or an online repair manual
  • when the flasher fails, it can cause the lights to stay on. to test the system, insert a jumperwire, between the terminals like this and if the light stays on, replace the flasher. if you donot know the location, refer your user manual

03 toyota 4 runner vsc trac and trac off light are on, what´s the problem with?


VSC stands for vehicle stability control and trac is traction control they are incorporated into the ABS system all receive signals from the wheel sensors you must use a digital ohms meter to find the one reading different and replace it in some cases you might find bad connections at the plugs.in any case your brakes will work fine you just wont have ABS braking or traction control

My check engine light along with the vac trac light came on this morning on my 2005 4Runner. What causes this?


Have the vehicle scanned for codes and do the repair according to what the codes indicate are the problem areas. Once a check engine light comes on for a particular item (eg vac trac light) that item will not operate until its code item is addressed.
There are several sensors that can affect the item illuminated on your vehicle. Have a qualified Technician do the repair.

TRAC LIGHT ISSUE


The trac light does NOT come on for the smog test. It has noting to do with the smog test. The trac light DOES come on when the Check Engine light comes on, when a failure is detected. From what I remember, the trac light WILL come on if the smog is a "dyno-driven" smog test, but it has nothing to do with the test, the trac simply comes on because only one wheel is spinning, just like it will when you are spinning on ice.. Hope this helps.
