brake system / traction-control dash lights all on (1 Viewer)

[PDPerry]

All the brake system and traction-control dash/idiot lights in my daughter's 2007 4Runner Limited have become illuminated. However, she has noticed no change in braking behavior. I had her test-brake in a gravel lot and the anti-lock system seems to be working correctly.

When she was in town last week (she's a CalPoly SLO student... Go Mustangs!) I checked her fuses & breakers and they all appeared OK.

Internet searches bring up nothing.

Anyone have any ideas of what I should look for prior to shipping her off to the dealer?

Thanks in advance...

Have you looked at the fluid in the brake reservoir? Maybe it's time for brake pads.

Fluid levels all good. Brake pads plenty thick.

Unplug the battery for a couple of minutes? My Tundra does something similar occasionally.

I'll have her give it a try and report back. Apparently having all these light-up is Toyo's way of notifying you of a number of potential issues...

I had a similar thing happen with my FJ a few months ago and it was a wheel sensor and wiring. The brakes worked okay and the dash was lit up like yours.

 

[PDPerry]

How'd they (or you) test for the wheel sensor?

I'm not sure how they test them. I read about the problem on the fjcruiserforum and it sounded like what I had. I was getting my FJ serviced at my dealer and they confirmed what it was.

Through the TIS computer system, lots of things are possible.
I think I'd pay the 100 dollars or so and find out what it is at the dealership.
