VSC TRAC and TRAC OFF Lights Stay On

[danielatx]

So today I had the negative battery cable repaired using a Lynx O.E/Battery Cable. After putting the battery back in, the check engine light, VSC TRAC, and TRAC OFF lights turned on and stayed on. These lights never turned on before I messed with the battery. When i put the key into the ignition initially the VSC TRAC and TRAC OFF lights would turn off but they would turn on as soon as I began to drive. I went to my nearest autozone and had them check the CEL and it gave the code of P2238. That was the only code it gave. I explained the situation and he said most likely the CEL will go away after driving 30 miles. he was right......the CEL light was gone. Now i just have the VSC TRAC and TRAC OFF lights that stay on. Anyone know whats going? If i keep driving will they eventually turn off? I never had this problem before repairing the battery cable.

VSC TRAC and TRAC OFF Continue to Stay On, 2003 4Runner V6 4.0 Sport Edition

So far I've driven a little more than 40 miles and check engine light is still off but the vsc trac and trac off lights still turn on. I was just wondering if anyone knew how removing the battery terminals and putting them back on would cause these lights to turn on. Did this somehow reset the system? Can I drive with these lights on? Would I have any issue in the future? I'm a bit worried with these lights now staying on.

If these lights are on can i still pass inspection?

I don't want to go to the stealership because they most likely would charge an arm and a leg to fix this.

It sounds like you reset the Zero Point Calibration in the computer (somehow involving the battery). It's a simple fix if you are comfortable jumping a few pins on the OBD-II connector, or the dealership can do it.

Mine had the same problem a couple years back, but I started to like the ability to drift a 2 1/4 ton behemoth, so I re-cleared the data and have ridden without traction control ever since. It's quite fun, actually.

In addition, it wont cause you to fail inspection. It will only come on when the vehicle is running, and starts to roll forward. Nowadays, all they do is plug in to your OBD with the engine running (and parked), check for any Catalyst specific codes, and send you on your way. They could care less for traction control.

Great Forum!

Thanks for the reply Jeff. Yeah i haven't felt any difference in driving my 2WD 4Runner since this happened. It's great to know i can still pass inspection with this issue. I wonder if there's a difference in mpg without the traction control?

so far i have been driving with these lights on and haven't had any problems. Love drifting my 4runner.
