ABS, Trac Control, & Brake dash light - Toyota 4Runner Forum

With the car is in park, in either in accessory mode or running, when I pump the brakes 4-6 times the ABS, traction control and parking brake dash lights turn on as well as makes a beeping sound. It only lasts for a few seconds then goes away.

I have recently changed all 4 brake pads and brake fluid. When driving around I don’t get any warning lights and brakes are responsive and don’t have any braking/stopping issues. Tested 30-0, 40-0, 50-0 and 60-0 all without any issues.

Any ideas what might cause the warning lights to come on when pumping the brakes in park?

What's the stored code? How exactly, did you go about changing the brake fluid? If you introduced air into the master cylinder, you'll need techstream or similar scan tool to bleed it.

Not getting any codes on code reader. Ran it numerous times, still no codes. Even had code reader going when I caused the issues still nothing.

I kept the tank for master cylinder full, never dropped below the minimum line and used a bleeder bottle with brake fluid in it so that the discharge hose end wouldn’t suck in any air.
