Car just had 120K check and first time driving, Trac Off, ABS lights flasked and car making lound humming noise from engine. 20 miles later, lights went off but humming continues. Loud hum, very evident when all fans, radio turned off. Seems to come through vents on driver and passenger side in front. What might this be?
Your wheels each have rotor speed sensors...
2006 LEXUS GX470 4 7L V8 ABS Wheel Speed Sensor RockAuto
These are easily bent or misaligned... and can be
put into a position of INTERFERENCE with the
(particularly ... in YOUR case "RIGHT FRONT")
ROTOR...
These parts ARE NOT CHEAP... and WILL
ADVERSELY impact the operation of BOTH
TRACTION CONTROL & ABS (anti-lock brakes)...
It is a WORK ERROR... while your BRAKES
were being "inspected" ... your
rookie dealer "mechanic" most likely did
something...
ROAD-HAZARDS "can" break these parts...
but reasoning with your fully functioning
brain... (OCCAM'S Razor)
Occam razor Wikipedia the free encyclopedia
You should NEVER HAVE LEFT... without
having a SERVICE PERSON making a note
of your ABS & TRC lights...
You do have rights... and government
licensing boards... In the unlikely event
your "dealer" FAILS to recognize their
obvious WORK ERROR...

When you hear the thunder of hoof
beats... Think HORSES... (not Zebras)

I have had many BAD experiences with
DEALERS... (& I trust my lying eyes)...
I'm just saying (in my opinion)... Get back to that
"DEALER"... pronto...!!

SOURCE: trac off and check engine light for lexus es 300
A week ago, on my Lexus ES 300 (2001), "Check Engine" and "Trac Off" lights came on. This coincided with me filling the gas tank to the brim to round the dollar to be paid. I cleaned the gas tank cap and the tank opening. However, both lights persisted. On the same day, when I turned on the car again, there was a hesitance, a stuttering to come on. Both "Check Engine" and "Trac Off" lights were still on.
The next day, the car wouldn't come on at all. It sounded as the battery was dead. I couldn't even jump start the car. So, I got a new battery from Costco ($59) and put it in. It took 15-20 seconds of cranking to get the car started. Once it was started, the engine sounded fine and the RPM normal. The "Check Engine" light was off. However, the "Trac Off" was still on. I cleaned the gas tank cap one more time.
The next morning, when I turned the car on, there was no problems. It came on instantly as it used to be, didn't have any warning lights, and drove smoothly.

Sounds as though when your battery died the engine imobiIiser locked down.
YOU MAY HAVE TO HAVE THE CAR TOWED TO A LEXUS DEALER AND HAVE THE MASTER KEY AND OTHERS REPROGRAMMED TO THE IGNITION...BUT
If you have your wallet key as well , try taking all to the airport. HOLD the card to the dash beside the ignition for at least 20 seconds, then try turning the key several times. I haven`t done an LS but the failsafe when a remote fails is to hold the key beside the ignition for at least 20 seconds ....
Also try the lock routine, but I think the issue is in dash..security needing to reboot to your key.
My understanding is that the lock routine re initialises the lock setstings when power is restored

the computer is bad and also these cars are known for the insturment clusters to go bad along with the computer. get them both fixed and it will solve your problem.
SOURCE: just got car service for 75,000 miles also had new
Sounds to me like someone has perhaps knocked the ABS sensor while working on the brakes. The ECU in these cars interlinks various stability and braking components. Go back to the service center and ask them to put a code reader on the car and get a read out. It may only require that they reset the fault codes, but do not delay. On some Lexus vehicles these lights will also come on when the battery has been disconnected and there will be a reset for the programs, but the TRAC off light has never come on on my 2001 when doing brakes or battery swap.
nice find an 02 with 75,000. My 2001 is over 160
