    Default Warning Lights Went Haywire

    My instrument cluster just went haywire. All the warning lights are on including the check engine light. The 4-Lo light is flashing rapidly. I want to say that I read in a post a long time ago that this might happen when you blow a fuse. I just cannot find that post for the life of me. If it is a fuse, which fuse would cause all this?


    Open to other suggestions.


    Thanks.Click image for larger version.

    I suspect that it's something more than a fuse, but I guess anything is possible. Maybe these will help.

    What is the air pump and what does it do? I remember I used to hear it right after startup and now I don't. One of the reasons for those lights seems to be the air pump.

    Check engine light : on
    VSC light: blinking
    Traction control light: on
    4-Lo light: blinking.

    Thanks for the PDF's.

    The bad news ............... it sounds like you have an AIP problem. (air pumps and valves)

    The good news ............. it is under warranty!

    Thanks. I just called the dealer and scheduled an appointment to take it in. My truck just turned 60K (60,055 actually). So I hope this means it is still covered. And if not, I did purchase the extended warranty with it, so hopefully that will cover it. Is there anything else I can mention to them to take care of since I will be taking it in anyways? Any other recalls or TSBs?

    Thanks.

    Toyota will have a complete list of all recalls for your truck. I suggest that you DO NOT LET THEM DO THE GAS PEDAL RECALL!

    Too late. The previous owner apparently had that done. I still think its jumpy though, and that's fine with me.

    I installed the OEM factory JBL nav unit. That's the first thing I thought too. So I checked every fuse in the truck and they all seem to be ok. I printed out the TSB and took it to the dealership. We'll see what they say.
    Do you have any ideas?

    Well, got a call from the dealer that the truck was ready. As soon as I get in the truck the damn lights turn on again. I asked what they did, and they said they cleared the code and drove it around for a little bit and it was ok. They didn't do the TSB AIP fix since it wasn't generating the correct code for it. Apparently, it was throwing a speed sensor code. So now I am thinking this has something to do with the nav install that just happened. I have no idea where to start troubleshooting and what it is I need to be investigating. Also, the weird thing is, I don't hear that air pump after startup. I used to hear it every morning, in fact, I would wait to hear it before putting my truck in reverse and taking off to work. It was like signal for me that the truck was ready. And now I don't hear it all. So either they are lying, or they are telling the truth and somehow that code is also somehow related to the damn air pump.

    I am really lost guys. I seriously need your help. Any electrical gurus out there that want to help?
