Hello Scotty, I have a 2004, Lexus, GX470. Just recently a high pitch noise is coming from the driver side dash area. Also my brake, abs, vsc track, and vsc off light come on. No check engine light but oddly enough the abs work when I apply the brakes hard, and the pedal is not sluggish or hard. I am very confused please help.
Thank you,
MarineJesse
Besides these lights, do you have any CEL?
It seems your ABS system has some issues. You need to scan it with a high level scan tool that can read ABS codes.
Thanks, I got it scanned by a local mechanic and it has no codes. Tested the alternator to see if it was that and it’s good I’m very confused
There should be some stored codes. You need a higher level scan tool to extract them.
I’ll have to take it to the stealer ship to see what their diagnostic technician tells me. I own a thinkcar sd6 scan tool and the mechanic I took it to has a Bosch system. Still nothing. Thank you for your help
