Default Zero point calibration

Can anyone give me instructions to do a zero point calibration on an 07 LX470? I have found posts for other Lexus vehicles but I think the ports on the LX may be different. I'm trying to get the VSC Trac/VSC Off lights to turn of. I do not have a CEL light on. Thanks for your help.

Ports on the diagnostic connector appear to be the same.

You may have a wheel sensor going or gone south, a sloppy rack and pinion can cause the same issues. So can suspension modifications, the deceleration sensor, and/or the steering angle sensor.

If you don't want to diy it, take it to a dealer (either Lexus or Toyota should be able to handle the issue.

I did a quick search in the 100 series section on MUD, check http://forum.ih8mud.com/search/58242...&o=relevance&c[node]=26

I don't think it is a sensor. I just had the alternator, timing belt, and water pump changed. From what I have seen hooking a OBD2 scanner can cause the VSC lights to come on. When the car is started there are no lights but when you start moving they come on. The VGRS flashes also for about 2 minutes then turns off.

Okay I figured it out. Here is a link to instructions on how you clear this issue. https://www.clublexus.com/forums/att...alibration.pdf

The ports for the LX470 are 4 and 12(they are right on top of each other). I believe it's the same as a 4runner. If you follow the instructions it should clear up the issue. Just make sure you are parked on a level surface and that the steering wheel is straight when doing this procedure.
