Electrical problem on 2nd gen

So I was driving this morning and all of a sudden, all these dash lights go on, along with the speedo becoming none reactive. No noise or other jolts.

I have the rpm, fuel, and temp.
All fuses I checked seemed to be fine.

Ideas?

 

Abs, e brake, "4wd" icon in the lower right, check engine, trac, tpms light. I didn't not have the seat belt on at the moment of the picture, so that is ok.

EDIT: power windows, backup camera and A/C don`t work either.

 

See if you can pull a code using a scanner, if not look for wiring damage that might of been cause by rats/mice.

 

Do you have a scan gauge or ultra gauge hooked up while driving? I think I remember a thread a few months back where someone had the same issue and it may have been related to that. If I find the thread I'll update my post with it.

 

I do not have one at the moment, but am thinking of getting one now. Isn't the scangauge meant to be hooked up while driving? as it tells live mpg, tranny temp, etc...

 

I am using a friends obdII reader today to see what codes may have been thrown. usually not rats or other vermin in my area that would do that, but ill check to be sure.

 

In other marquees I've owned that was a symptom of a bad ground connection. Usually corroded.

Don't know on the Tacoma, but 3-4 underhood/chassis locations to inspect would not surprise me.

 

I'll check thanks!

 

Obd2 scanner read an error code P0500.
It's either a wheel speed sensor failure or some part of the wire etc, or at worst case a faulty ecm.

 

Check the front wheel sensors the readings are taken from there

 

Try disconnecting the battery and ECM connections, cleaning them up and reconnecting. Loose or corroded grounds is also a likely suspect. The fact that it still runs fine is encouraging.

Damn mice!

I have a UltraGauge they are designed to be plugged in and left on. You can customize the display for what you want. It will also pull any pending or stored codes. I have no experience with scangauge.

Damn mice!

Good luck

 

i had the exact prob, between replaceing a front abs wiring harness, on one wheel and disconnecting the battery while replacing wiring harness it was fixed

 

its not always the abs sensor, i had to to a resistance check to find the bad wire on the harness, it goes from wheel abs sensor to under the hood, where it plugs into the main harnesd

 

So would i pull the harness from the abs sensor at the wheel and check the resistance there? what kind of numbers are normal?

 

Check your IGN1 No. 2 fuse (10 amp) in the panel by your left knee when in the driver seat...

Had a similar problem myself.

ill double check that fuse, but dont think it was blown when i checked it yesterday.

 

and to all:

would a bad abs sensor, harness, ecm, blown ignition fuse, and/or some other problem cause my
(abs, trac, ans speedo) and (a/c, heater, fan, and power windows)
to go out all at once?

i dont see how those two groups would be connected?

 

Check the fuse with a meter. Every single one of those items you mentioned are tied to the IGN1 No. 2 fuse....

 

Good point.

Thanks for the info! Ill do that when i get home in about half an hour.
