Help! Dashboard looks like a christmas tree!

My dad's taco just had all his dashlights just go on.‎ I checked the codes and this is what they are.
‎
P0224‎
P2400
P2401
P0705
P043f
P043e
P0420‎

Any idea what it could be? It's an 06.

 

Google my friend... all codes are the same regardless of make or model.

 

Yes, I have googled the codes and I know what they all mean. But that doesn't explain why every dash light is on.

 

Just guessing here but my old pos college car had a similar problem and it turned out to be a bad alternator that wasn't charging the battery aka the computer in the vehicle got confused....just my .02!

 

did you check the fuses . too many codes all at once like this and youve got a loss of communication to the pcm . in other words a loss of power or ground

 

Like they said could be alternator... does it start?

 

Start truck and see what stays on, pics show lights but tach. says it isn't running. My 06 did it once and it was a fuse.

 

Lol but isn't the battery light always on before starting? Guess I'll find out myself in 40 min haha

Had a Grand Cherokee that did this to me once. Battery kicked the bucket without warning - internal failure. High temps in summer can be harder on batteries than cold winters.

All the dash lights lit up, and the Jeep died when it had been running fine literally 10 seconds ago. Couldn't restart it. Tested and voltage showed like 10.1. New battery fixed me right up. So I'd check battery, alternator, and fuses/grounds, assuming CEL was not previously on, reset everything, and see if you get any new codes. If the truck runs fine, you should be good. Good luck!

 

I have seen this a few times and once on my old Isuzu truck. It was a ground through the alternator slip rings ( worn out ).

I'm going to say it is likely a ground issue... All of these LEDs come from various control modules so it has to be a common point of failure. IMO

 

Similar issue with my Tacoma, I just had my check engine light come on and the codes were P0504, P3e04, P3f24, P0124, P0224, P1900. I dont have the battery light on like
Nunavut. I checked all the fuses..all good. Does anyone still think it could be a ground in the alternator?

 

What was the outcome? I have a similar issue with my dash. Except I lose my tach and temp and the traction and ABS lights go one while i'm driving. I did just take out my battery and put it back and that's when it started.

 

Good point.

 

I know this is not a taco but my wife forgot to put the gas cap on her scion and drove it for a day ended up with about 8 codes put the cap back on had to put it on the computer to clear the codes no problems after that.

 

No...it's actually not possible as the battery only goes in one way and the cable don't reach the opposite sides.

 

Some cars monitor the lack of pressure from the gas cap being open. Had that on my Lexus.

 

First thing I would do bro is take a multimeter and check the positive on the alternator......if your alt is going out it will cause all kinds of issues/codes

 

With the truck running it should read anywhere from 13-14 volts
