05 GX VSC OFF & Center Differential Lock lights on
The VSC OFF and Center Differential Lock lights come on yesterday on my wife's 05 GX470. I connected the OBD2 code reader, but it says "no error codes found". Since there are no error codes, I am at a lost in trying to figure out the root cause. Any suggestions?

Try turning off the center diff lock, just looks like someone hit the button and locked it up, no big problem. The "VSC off" light comes on with the diff lock.

I did that. When I press the center diff lock switch the center diff lock indicator on the dashboard blinks, but it never goes off. I guess a visit to the local lexus dealer is order tomorrow. I'll post when I find a solution to the problem.

If it doesn't get used much, it could just be stuck. Try turning it off and driving around in figure 8's in a gravel/loose surface parking lot so it can unbind and release on its own.

Good idea. I cannot recall a time when it was turn-on. I think it has never been used. the GX has never been off-road. I'll try your suggestion tomorrow.

It was stuck from lack of use. Before I took the GX to a gravel area as suggested by IanB2, I read the manual carefully. It suggests to drive it in reverse when the VSC OFF and the Center Diff Lock lights are on. I put it in reverse in my driveway, and before I go to the end of the driveway the lights went off. IanB2, thanks for the suggestion. I bet doing eights on a gravel road would have unlocked the center diff also.

Agree. Owner forums are great. They provide an avenue to share experiences and educate us on solving problems. I am a DIY on all my vehicles. I do the work not only to save money, but most important for the satisfaction that the work is done right using the highest quality parts. I hope this thread help other owners solve similar problems.

Just a thank-you to you guys for posting this thread. Had the light, envisioned expensive repairs, did some gravel 8's in reverse, all is well. THANKS!

The only time I had to do figure 8s was to recalculate my MDXs navigation. Those people on the top level of the parking garage were probably like, what the hell is that guy doing.
