Well, Claremont Toyota has had my FJ for 10 days now. (By the way, their service has been EXCELLENT so far..)
I was having an issue with the "VSC OFF" light being constantly on and after about 20 minutes of driving, this light would come on, and blink:


The computer didn't throw any codes, but they replaced what I think is my "4WD computer" ?
That got rid of the VSC OFF light, but the other light still persists.

They then replaced a sensor in the rear diff...no luck...

Last I heard, the mechanics were pulling their hair out trying to figure it out.

I miss my FJ... :mecry:


UPDATE:

Just got off the phone my service guy. He was confused. They fixed the 4wd indicator light by replacing the computer, and the VSC OFF light is the one still on.

Matt, is it possible your new 35s are not all the same diameter?

Just get it back and drive it till it stops - then give it back to them - it might heal itself - not sure if I could go 10 days without mine - hope everything works out - :(

Ask the dealer if they have gotten in touch with the field technical specialist (FTS) at the region office yet. Ask the dealer to have the FTS come and inspect your FJ too if the dealer can't diagnose the problem and has already replaced the computer. You also may want to call the national 1 800 CR number and open a file. They keep a national list of vehicles down and how long they have been down. Keep on them nicely, but firmly! Good luck!

Very good point. You may want to document everything just in case you have to go that way...

Sounds like a sensor issue - although I don't believe they would have swapped out the computer before they replaced (checked) all the sensors - worst case scenario - it's an actual 4 wheel drive mechanical problem - I doubt it - seems electrical - warning lights - very confusing -

You need that thing back real soon brother -

I had a similiar problem on my Infinity G35. The VDC light (same as the toyota VSC) was on constantly. The problem was worn brake pads. When the fluid in the reservoir dropped it would trip a sensor and throw the lights on. Until I replaced the pads I filled the reservoir with fluid and it turned the lights off.

I am not sure the FJ is like this. Just throwing it out there. But ,since the FJ uses the ABS for VDC just like my Infinity does, it might be worth a little peek in the reservoir to tell me I don't know WTF I am talking about.:lol: J/k, just thought I would throw my .02 in.

I am sure your dealership has a troubleshooting tree they follow and hope they find the problem. And sorry to hear about the parting with your FJ for so long. I am no stranger myself to searching for problems for a few days sometimes. I work on aircraft and you don't want to know the "gremlins" we chase around sometimes.

Matt, the parts are on back order and the final piece is coming down from San Francisco. I was told that they should be able to get you ready by maybe Wednesday. They've order some expensive parts!

Thanks Tony! Who did you talk to over there?
I talked to them earlier today also. The mechanic thinks he may have figured it out.

They think it is a 4WD locking mechanism in the transfer case, I believe.

I guess it was not disengaging properly and the FJ still thinks it's in 4WD even when it's not. I sure hope that's what it is!
