    My Toyota Avalon 2000 xls was totally dead after I parked it on a main road, got it jumpered, did not work. Replaced the battery at a workshop. When the car was received back the remote door key stopped working; the display resets it self to initial setup even if the time date and other functions are set it forgets it when you restart the car. The radio also stopped working even with the engine running it does not come on. Checked the fuses for continuity, they all seem to be good. What could be the problem? Is there a relay that connects power to the radio and the display computer system? Where is that relay, if any? Can someone help before I take it to a dealer? Thanks.

    :confuse: :sick: I Have a 2000 Toyota Avalon XLS, My car battery has been dying so i went out to jump it one morning every thing was hooked up correct. When i put the pos an neg cables to the battery of the car then the horn honked an i heard a click or pop noise. i quickly took off the cables an checked the car an all the gauges went hay wire. after charging the battery an trying it again now nothing gets power jst the security light. I thought it was the computer until i bypassed some wires to the ignition an all the accessories come on only while bypassed. an the key is loose an lots of play. i took of the box under the ignition an bypassed power to that as well an it works while bypassed to. if itwas a computer i dont think it would do any of that. i think it has to be a fuse or relay. I just have to find it. Can any one help? i have a Toyota mechanic coming over to check an i will post our findings. but if any one can help in the mean time.
  • Based on my note on this, I had to take the car to the agent shop. They reported to me that the fuse base was damaged the replace it. Now everything is working.

    Have a 99 Avalon, 245k, still drives excellently - great car. Started the car but wouldn't shift out of park. Did the gear shift lock bypass with a screwdriver but noticed that the power mirrors, wipers, gauges, clock, radio, power windows, and auto head lamp out. Curiously, parking and headlights work and the radio will eject cd's. Checked all fuses and relays and are fine. This happened several years ago with the shift lock and changing a fuse fixed it, but now the situation involves more systems. Thinking it could be the integration relay or a loose radio wire. Will check the after market radio connections since that won't cost anything. The integration relay is costly, so I would like to ask if there's any other suggestions that anyone would have. Thanks!

    Over the years many members have posted that a "green eye" on the battery top does not guarantee the battery will start the car. But it should start.... we all know a green eye means the battery is fully charged. So it works, right? Wrong !!

    This is one more post to confirm what the many have said, "It (the green eye) just means the battery has a certain number of volts." It's true. I replaced the '07 battery yesterday... 47 amps... and an "eye" as green as a golf course. Watch for the warning signs: Slow to start, some lights flicker, dome light dims, over 3 years in service, etc. Mine made it to the dealer, barely.

    Thanks to all who have mentioned this in the past. Enjoy the Avalon, great cars..
  • I had a real adventure with my 2006 Limited. Left an interior light on and drained the battery.
    When we tried to jump start it, it wouldn't turn over. Found out sometimes you have to wait 15 - 30 minutes for the computer to realize the battery is recharged (my guess, confirmed by a Toyo tech. They're not sure why.) Anyway, do yourself a favor and do what Consumers Reports recommends, replace your battery after four years, just to keep life simple.
    One of the best buy batteries is the Wal-Mart one at around $70, and they put it in free. Otherwise, my Toyo dealer only charged about $110, which wasn't too bad.

    Does it start with the fuse removed from the CD?
    Sounds like you possibly have a short in your CD circuit.
    Electrical problems can be very hard to chase down, and most mechanics won't work on them because it takes so much time and owners get agitated at the cost.
    Did you try Googling "Toyota Avalon 2001 wiring diagram"?
    If that doesn't work, call the dealer and get an estimate. Maybe it's a known problem to them. Don't turn them loose on it without a firm estimate.
    Good luck!

    Bottom Line: it might be a faulty stereo amplifier

    I have 2008 Avalon Limited. I had all the problems you had. My battery kept draining and I went through three batteries, all the while, the dealership insisted it was my fault for not driving the car enough. The last time it happened a few weeks ago I took the car to another dealership who did a more thorough examination. The culprit was a faulty stereo amp that would not shut off when the car was turned off. I had it replaced under warranty.

    If I had not had the extended warranty I would have argued the problem started under original warranty, because this issue began before the manufacturers warranty expired. Don't let them blow you off.

    With keyless ignition (Avalon models 2005 and up), you will likely discharge your battery if not in park because ignition will stay in accessory (always on). I have tried that on my 2006 Avalon. Anytime it's not in park, it is going to discharge the battery period.

    With the key type ignition, you will not be able to remove the key from ignition. Try leaving your transmission out of park overnight with the key in the ignition. By morning your battery will be discharged.

    1997 Avalon: : I had struts & shocks put on all 4 corners,when I got it back,the ABS light & TRAC OFF were on & flashing.I had it hooked up by an up to date scanner & it showed no codes were on.Any ideas? Thanks.
  • Probably your scanner can't read ABS codes. Sounds like a wheel sensor got disconnected or damaged.
  • Thank you very much, I greatly apprieciate it.
  • 2006 avalon w keyless entry. Sometimes when I start the car I get three quick bells does anyone know what it means. I will also occasionally get a single ding when I shut the car off. Great car but I am curious. Thank you
  • Having same problem. Have replaced 3 batteries, stereo amp as well as starter switch. Car just now will not start. Help!
