ABS/Brake/SRS Warning Message

[be001]

Hello,

2014 model here with no previous issues. A few weeks ago, SRS warning light came on. I tried replacing the fuse but it didnt work. So its just been on since then. But the display is flashing warnings for all three - ABS/Brake/SRS. Also the dash shows the warning lights for abs, srs, low tire pressure, yellow exclamation mark and antilock brakes...The brakes are also very hard to press down and the car is endlessly beeping - the same beeping sound as if you had accidentally puled the e-brake while in drive. The car will go into drive.

I tried replacing the 12v, and checked the brake fluid. Any ideas on what I can check next?

This sounds like a problem with the brake booster assembly; it could be a failure, or it just might need recalibration. Any Toyota dealership should be able to read codes from the diagnostic connector under the dash, some auto parts stores may be able to read codes, or you can do it yourself by obtaining a cable and a copy of the Techstream software (cable and cracked versions available on Amazon etc).

As it may be relevant to your case, see the thread at https://www.myrav4ev.com/threads/co...-anti-skid-warning-lights-on.2611/#post-30720

First, read the flash codes of these systems using a paper clip and the diagnostic connector DLC3*.
and let us results.

As mentioned above, connecting pins TC and CG pins together will cause the system to display trouble codes on the instrument cluster by counting the number of flashes of the warning lights. Although this is a safe and easy test to do, do not attempt if you do not feel comfortable.
