Thank you all for the suggestions.
 
It worked when i removed the negative lead and let the system reboot. Amazing! Thank you very much George.
 
Although, i have new problem which is my ODO showing as 3098 instead of somewhere around 92000. Is there way to display correct ODO??
 
I can drive safely now. Thank you again

Great! I know how you felt. Saved me some bucks. I picked this info up on another forum.
 
Sorry, can not help you with the ODO, but hopefully someone out there can! Might also try the Toyota Avalon forum.
 
Thanks,
 
George

I have a 94 ls400 with speedometer, temp and clock probs. Is this similar to yours? How did the fix work?

Sounds like a similar problem. I'd call BBA Remanufacturing and give them the specifics of your problem. The refurb. they did to my unit works fine( the illumination for all info. comes on immediately) except the speedometer needs to warm up and speed needs to be greater than 25 mph before it "springs or pops" up. Not sure why this happens bit it is only a minor irritation and only occurs when the car is first started.

Hey guys,
I had some service done to my car, and I assume they must have left the battery terminals loose, because the other day I was leaving work and the car wouldn’t start. It was totally dead. Once I jiggled the battery terminals, everything seemed to be fine... Until I noticed that the instrument panel was no longer lit or working. The car is in the shop again right at this moment, and they’ve told me I need a new instrument panel or something crazy like that. I was awaiting a call back for the price quote when I decided to Google some info, and it led me here. I can’t describe the elation that I will have if this little trick solves my problem. Seems to be the same situation (battery disconnected, cluster no longer lights), so I’m very optimistic. I’ll let you know, but if there’s any advice you can offer in the meantime (before I get to my car and try this out), please chime in! Thank you!

After disconnecting the leads, make sure the terminals are clean for good contact. Also, I would run a battery test to make sure the battery is good. In my case, the battery needed to be replaced. After everything is cleaned up and the system rebooted, connect batery cables. Hope the instrument panel lights up!
 
I got the same story about repairing or replacing the instrument panel. Fortunately, this worked for me!
 
Thanks,
 
George

Lights will not go out. Please help. All suggestions welcome. by paul83

Have a 1990 Lexus LS 400. Had trouble with the engine. Had my mechanic put a used 20,000 low miles 1992 Engine in the car.
 
The car runs perfect. Also had him put in a new alternator. He did not hook all the wires on the alternator. Drove 150 miles and the car stop. It was running on battery only. All the lights came on dashboard. Radiator, brakes, battery etc. He fixed the alternator but all the lights are still on the dash board. He took battery cable off and lights on dash board went off but came back on again.
 
The battery is almost new. Do you think the problem can be the defected battery cables could be causing the problem. He charged the battery and ran the car. Next day would not start and battery was dead.
 
Please do me a favor and if any one can think of what is wrong let me know. The car runs perfect and every thing seems perfect but the lights on the dash board will not go out. I can not get the car inspected until the lights go out. I would appreciate any help or suggestions.
Thanks, Paul

I had the same problem today.I have a 2001 Toyota Avalon XLS and non of my instruments cluster was working. I couldn't tell how fast I was going , How much gas I had left or the odometer. The dealership was going to charge me $200 just to look at it. I took it home and checked all the fuses and it was still good. Luckily I found this page and I disconnected the Negative lead and waited for 15 minutes. Plugged it back in and All my gauges were working again !!! Thank you !!! You guys saved me a lot of money !!
