2004 toyota sienna warning lights

low tire pressure warning lite

Hi there,

If you've had your vehicle computer codes read and determined no issue with the VSC circuit, then you just need to cancel the warning light.

I've made up the following instructions, on how to clear VSC & TRAC Warning lights:

Zero Point Calibration of Yaw Rate and Deceleration Sensors Using Paper Clips (or jumper wires).

First, locate the 16-pin ODB II connector under the steering wheel (beneath the dash). The pins are numbered sequentially backwards from right to left (from the wide side of the connector looking at it from underneath).

Take two normal-sized paper clips (or suitable jumper wires). If using paper clips, straighten one edge of one of the paper clips. For the other, bend it open to a 90-degree angle (like an elbow).

Insert one paper clip/wire into pin # 14 (Ts), and the other paper clip/wire into pin # 4 (CG) of the OBD II connector - DO NOT allow the paper clips/wires to make contact at this point.
Refer to diagram below:

1. Ensure the shift lever is in "P" range.

2. Turn the ignition switch to "ON" (not start).

3. Momentarily touch the two paper clips/wires together (short) and separate again (open) - Repeat this process 5 times (within 8 seconds of turning ignition on).

Verify that the VSC indicator light is illuminated, indicating the Recorded Zero point is erased.

4. Turn the ignition switch "OFF".

5. Remove both paper clips/jumper wires from the OBD II connector.

6. Turn the ignition switch "ON" (not start) - wait until VSC warning light turns off (approx. 20 seconds), then wait 2 seconds.

7. Turn the ignition switch "OFF".

9. Re-insert paper clips/jumper wires to terminals #4 & #14 of the OBD II connector (as per above diagram).

10. Turn the ignition switch "ON" (not start) - VSC warning light should remain illuminated for 4 seconds, then start flashing at 0.13 second intervals.

12. After VSC warning light flashes for 2 seconds, turn the ignition switch "OFF".

13. Remove paper clips/jumper wires from the OBD II connector.

Drive your vehicle to confirm VSC & TRAC warning lights have been reset and no longer illuminate.



"If this has helped you resolve your issue, please be kind enough to leave a testimonial"

The fuse block is located under the left side of the dash. The 10amp fuse you're looking for is the second from the bottom on the right side. It should be marked Tail. Hope this helps.

If the dealer/mechanic did the service early the light will come on when service is DUE. Go back to him and have it turned off. Search the web someone may have the procedure posted. Usually simple. Google "Toyota service light reset" or "Toyota Maintence light reset" Try this one

1. With the car started (ignition on), set the LCD odometer readout to total mileage (not trip A or B).
2. Turn the car off (ignition key to the OFF position).
3. Push in AND HOLD the button/knob that switches the odometer
4. Turn key to ON position without starting the car. You will notice the maintenance light blink and go out.
5. Release the odometer button/knob.
6. Turn key to OFF position.
7. That's it! The "MAINT REQD" light has been reset to warn you to change your oil in another 5,000 or 7,500 miles or so.

That light on the toyota sienna is drumroll please,,,,,,,,,, the air in one or more of your tires is low!! It would have made more sense to have a picture of a tire or the word tire or whatever,,, not sure what that symbol actually is, but check the air in all your tires and One will most likely be much lower than the rest. The tire pressure on the sienna I believe is 35 psi all 4 tires, but you can double check by looking on your doors.

That light means that you are setting the tire pressure guage. there is nothing wrong with the van.

1. Remove the dash around radio (just clips)
2. Remove 2 screws pointing up . (You do not need to remove screws which are parallel to the floor)
3. Remove screw pointing up on the bottom of the dashboard on left side of the driver (near left leg).
4. Remove 2 screws pointing up in the instrument cluster area.
5. Put car in 1st gear and gently remove black plastic surrounding instruments (it will have ait vents, so slide it carefully out not to damage foam insulation on air ducts; start on the bottom hear steering column) ; unplug connectors to clock and emergency flashers.
6. Remove 2 screws, now exposed, near instrument area, holding dashboard. (that was what I spent most time on, I didn't know about this screws.
7. Now gently remove (or move up) dashboard (around instrument cluster and heating controls.) Start next to ignition (careful not to damage the bulb next to the ignition.
Since you only need to get to the heating controls block, I only move up the dashboard next to it.
8. Remove 2 screws that hold the heating control and slide heating control out . This step is unnecessary If you totally removed the dashboard.
9. Pull out lever controls for fan speed, zone and temp
10. Use the screwdriver (flat) to pry 2 plastic tabs on top and on the bottom of heating control so black cover can be remover.
11. You did it! two bulbs are going to be under the cover.

tire pressure.

Is this it? If so, it means check your tire pressure.

The warning light that looks like a pot or kettle with arrows is the "Low tire pressure warning light*" I found the answer on the Toyota web site by registering, logging in, entering my model and searching the owners manuals for warning lights.
