2004 sienna vsc and track off problem

I have no check engine light or any malfunctions in my van, but when I start driving the VSC/Track off lights are coming on. I checked the brake fluid level and increased tire pressure to 5.1 Psi. What else can I do?

Since the VSC uses the same sensors as the ABS, you may try resetting your ABS. With the engine off and the key in the on position, you press the button until it flashes three times. If the engine light comes on the VSC comes on as well, could your engine light bulb be burnt out? Hook up an OBDII reader and see if you have any engine codes reported.

I have retrieved 39436263 for VSC and 94 and 95 for ABS

What button I have to press?
