03-09 Lexus GX470 ABS,VSC TRAC,VSC OFF, steady chirp sound. DIY fix.

My car does this as well, no beep. Just only when I turn my headlights on.

Interesting, Ive heard it can also have to do with ABS or BMC motor. I will check my battery first. Thank you!

[@alexpellman8637]

Yeah I’m thinking the abs brake booster pump is failing

[@54jclop]

Did you ever get a soft brake pedal?

[@savagenez9584]

@@54jclopI actually did, but I could still brake. The alarm went away on its own eventually. All I did was gave the brakes a few pumps before taking off to activate that motor/pump and the lights went away. Its my temporary fix when it comes on for now lol

[@savagenez9584]

@@alexpellman8637same here, that is the reason the sensor goes on and off at times. I can hear the pump grind/kick in

[@jamesirwin3507]

I have the same issue but no brakes. Im thinking brake booster pump going out?

[@Babyfather2.5]

Some people say it's the gas cap

[@alexpellman8637]

I’m having the same problems and I know it’s not the battery I changed it just over a year ago. Did the issues start happening again?
