2002 4Runner - ABS, Trac, Brake & Check Engine Lights all on, High Pitch Alarm

[lanbe104]

Hello Everyone,

Please Help!!!

My 2002 4 Runner has all of the warning lights on, a very high pitched Alarm sound inside the vehicle and my brake pedal is very hard to push, as though the power brake motor has failed.

Where do you recommend that I start?

Thank you!

Could be as simple as a bad ground or battery terminals or potentially the brake booster or brake hydro motor.
edit; TRAC VSC and ABS lights on

DONT DRIVE! Your brakes will fail very soon, I had this happen! The issue is you blew your 60 amp ABS 1 fuse and possibly the ABS 2 fuse. It's a simple fix but can be dangerous if you drive like this.
