I'd try disconnecting the battery. Leave it off for 5 or 10 minutes then reconnect it and see if the light is reset.

Does it not have a push button on the lower left dashboard to activate and deactivate it?

 

[raylo32]

Chandler may be on to something here. IIRC my Tacoma has a switch that cycles the traction control on and off. maybe you pushed that inadvertently. Worth a try anyway.

[/QUOTE Yes, it has a button on the front of the console for that, right in front of the gear shift,,, but it doesn't do anything when I push it, or hold it down. I was hoping that would work, but it didn't.

No, I've tried that. It HAD worked before, to turn the traction on and off, but it didn't work THIS TIME.

I thought of that, at first, since I'd done that before with older vehicles, but this vehicle has so many electronic settings, that I was afraid that a lot of other lights might "pop up".

 

[raylo32]

That won't be a problem. At most you'll lose your radio and seat memory settings. One more thought... it might be possible that whilst changing wheels you bumped one or more of the ABS sensor wires. Have a look at those wires and connectors at each wheel. Those signals are critical for the traction control function and it won't work if one is inop. Only thing about that that puzzles me is you should then also get an ABS inop light. I have never had any of these lights in my Tacoma so not 100% which ones you should see.

Have you rolled the vehicle at all. It may take a few rotations of the wheels to acclimate it to the settings.

No,,,,,,,,,,,,,no the ABS light is not on. Only light on is the "skid marks".

If you've tried resetting everything, which it sounds like you have, this would be the next thing to check, including checking to see if one of the sensors itself got bumped out of position, so that it's not getting readings.

Well,,,,,,,,,I was "out of town" this weekend. Vehicle ran the same as always with the light on,,,,,,,,but, after about 150 miles,,,,,,,,,,the light is still on. But thanks for all the suggestions!

You most likely need to perform a zero point calibration procedure. You can do it with certain scam tools or if you can find the correct pins in your obd2 connector you use a paperclip and there's a certain procedure you have to follow. Like you have to put a paperclip in 2 different pins and touch them together 4 times or more within 8 seconds and turn the ignition on and off a certain number of times. Can't remember whole procedure. It should reset the sensors correct. Scan tool is easiest if you can find one that will do the calibration reset

 

[toolturnr_1281]

Scan not scam.. lol

One simple thing to try. Drive the car in reverse for 5-10 feet. Perhaps that might reset it.

 

[DanDIY]

Sounds like the light you're referring to is to indicate that you are experiencing poor traction and that the Traction Control system has engaged. On my car that's what it means, and I have a separate light that simply says "TRAC" to indicate that the status of the Traction Control feature, overall.

One other thing you can try is to drive a block with the Traction Control on, and then drive a block with it off. Maybe that would reset it?

DanDIY the zero point calibration reset that i posted is the only way to reset those sensors. It resets the sensors for the traction control system and vehicle stability control system that are causing his light most likely. The system also works with the abs system. The light staying on is a very common issue that happens after having suspension work or in his case having the vehicle up and rotating the tires. Is a very easy reset with a scan tool but you can also do it with paperclips and jumping the pins in the obd connector. Disconnecting the battery, driving backwards, raising truck up and driving with wheels off the ground won't help. It's a calibration issue that can only be fixed by resetting the sensors.

(1/24/2023) Update: The traction control light is still on, vehicle has been running fine with max gas mileage showing. Tried the traction control button, can push it multiple times, and the light doesn't even blink. Haven't been in a situation when I "know" a wheel is slipping (or spinning) Not sure if the actual traction control is engaged, or off, but the light is steadily on. How would you tell "with AWD"? With actual 4WD, you could tell if it's on or off, but with AWD it's only supposed to come on when "A" wheel slips? I've tried all the suggestions offered so far to no avail,,,,,,,,,,except shorting out the pins, which was suggested today. I had a BMW that I had to do that with, so, I know what you are talking about, BUT, you have to know exactly which pins to short (positively), OR you'll really screw something up bad. Do appreciate all the suggestions!!

 

[Myrod]

Oh, and yes, I already tried "blocking up the whole vehicle", and running it and as you said, it didn't work.

Actually i said that wouldn't work. See if autozone or other parts stores have a diagnostic tool or just go to tires plus, Firestone or dealer and perform the reset. If light is on Traction Control should be engaged even in this scenario
