2008 tundra electrical problem

hi.. i have a 2008 tundra CM and i was driving when all of a sudden all the electrical inside my truck just went dead, engine still works and runs.. i have not done a thing to it recently... it still starts up and runs

the parking brake light is constantly on, ABS light is constantly on, tire pressure light is blinking..

all electrical doesn't work on the inside (AC, stereo, window switches, door switches)..

i looked at the electrical cables and they're still good..

i have a 6 month old Northstar battery which is still good..

any suggestions on what could be wrong?

i just can't figure it out

thank you in advance for your help

 

Check your fuses?

 

Fuses are good..
it does not come out of park.. but I can take out the plastic piece next to the shifter and push the button to put it in drive..
I don’t know if it’s the alternator.. voltage is at 12 if the engine is on or off.. checked it twice

 

Would that explain why none of the electrical on the inside of my truck is not working?

 

Yeah, that north star is one heluva battery. I could see it carrying a failing alternator for quite a bit longer than most others would. Ideally 12.5 - 12.6 ish volts when truck is off. When running (say just started) mid 13 volts and up is what id want to see.

For the quirky electrical issues... Not really something that can be trouble shooted very reliably.

Something you can try is to disconnect the battery for 15 - 20 minutes to reset the ecu/ecm. A cheapo code reader might actually pull the exact issue since it effected such a wide range of components.

I would like to mention there are some odd safety quirks with in tundras. Few months back i managed to blow a fuse for my rear brake lights. Unknown to me i try to start the truck and nothing. Im pretty sure i wasnt able to even turn the key.

Just throwing that out there cause it may be something easily remedied.

 

Did this ever get solved. Having the same issue.

 

Check your alternator on a lot of toyotas when you get all lights on dash(referred to xmas lights in land cruiser world) is failing alternator. With a multi meter should see around 14 v give or take a few when truck is running.

 

Faulty ignition switches can cause issues too

 

I would check grounding points from inside the cab points, possibly loose, damaged or corroded... Check battery as well for function, and load... I've replaced Optimas at 6 months due to loss of holding a charge.

 

Did you ever find the problem? I have the exact same issue after installing a light bar. Fuses, relays, battery, alt all good. The alternator just isn't being told to charge. Also found that the fuse panel under the dash doesn't have power on the right side fuses. I have no clue what that means since the power going to it is good.
