Please Help Me Identify This Crazy Problem!

[dpolcino]

Hi, new owner of a 2002 SC430 and new member of this awesome forum!

So this is crazy! Sometimes when I put my key in and start the car, I get like a seagull squeaking noise coming from around the steering wheel area, then if I keep the car on for like 2-3 minutes, all the dashboard lights go on and I get a solid alarm tone! Of course when I bring it to the dealer the problem doesn't happen, and they have no idea what I'm talking about.

Luckily the last time it happened, I made a cell phone video of it. Anybody ever experienced this or have any ideas?!

Thanks!

I have never seen or heard anything like that before! Did you try having a mechanic use a code diagnostic machine? Maybe give Lexus a call?

[dpolcino]

yup, they had it for a week, no clue!

Did you try an ECU reset? There's the soft ECU reset to try first...

" 1. Get in your car and insert key. (It doesn't matter if you close the door or not.)

2. Turn the key to the on (not start) position.
3. Press the gas pedal to the floor.
4. Hold the pedal to the floor for five seconds, then turn the key back to the "off" position (don't remove the key), then release the gas pedal.
5. Wait 2 minutes.
6. Remove key.
7. Done"

If that doesn't help a hard reset is disconnect battery for about 15 minutes.

Nice ones! I ASSUMED they tried that but am not sure. Thanks, good idea.
