Truck will not start after dead battery/jump

Help!!! Got a 2018 tacoma. Truck would not crank this morning. My buddy jumped it off and the horn started going off. Got a new battery and truck will not read the key. Have to start it with the key fob next to the button. After start up I have no functions in the truck. No windows, radio, ac. Truck will not shift into gear. Check engine light, abs light, traction, all the damn lights are on light a Christmas tree. Getting messages also about check abs system, check vehicle stability system, check brake system, lane departure malfunction alert see dealer, pre collision malfunction, brake override malfunction. Checked fuses and relay. Brake lights are coming on when pressing the brake. I'm baffled

 

Make sure the battery connections are clean and tight. Might be an alternator issue.

 

Horn going off means it was backwards boosted, a main line fuse has burnt and requires a technician to replace.

it’s not a typical diy fuse. It’s bolted inside the junction box

 

He didn't accidentally reverse polarity jump start it did he?


Since you can't shift out of park let's start with that since it's the simplest, you have 3 fuses to check there. We know the STOP Fuse is good since the brake lights work but you need to check the ECU-IG No1 Fuse (7.5A) and SFT LOCK-ACC Fuse (5A) in the interior fuse box.

 

EDIT: well done changing the title brother.

Change the tittle to starting issues or whatever. HELP!!! And stuff like that is reserved for stranded folks in the middle of nowhere. Cheers

 

Agree on the string title - you will end up frustrated.
As for the issue, I am not a technician but I have heard and read that unless you get your connectors back on quickly with a clean connection when changing the battery you can mess up the PCM. Sounds like this might be the issue. If so you need to have your PCM reset. Perhaps someone on this thread knows more and how to go about resetting PCM. Hope this helps.

 

Oh the advantages of modern timesaving technology!!
What I have learned from TW is that one should not mess with ANYTHING electrical.

 

? ? Changing the battery can mess up the PCM? Resetting the ECU or PCM is done by -disconnecting- the battery, so putting in a new battery would have reset things. (Google it.)

Just to be sure, disconnect the new battery, wait 15-20 minutes, and re-connect.

If things are still messed up, it may have been something from the jump start. Start checking fuses as the others advised.

 

If indeed the jumpstart was connected backwards who knows what you burned out. Don’t want to scare you but I had a friend do this once on an older car and it blew everything on that car I’m talking every single bulb all fuses hell it even blew out the radio. Hopefully like @Bishop84 has mentioned it only blew a main line fuse.

 

Saw someone hookup cables backwards once. The plastic sheathing fell off, so quick, and immediately the bare cables started dropping through anything plastic they were laying on. Pretty sure both batteries were toasted, and one of those vehicles has those “gremlin” problems.

 

I will be the punching bag for the others for not helping right at this moment. For the future buy a

$100 NOCO GB40 1000A UltraSafe Car Battery Jump Starter, 12V Jump Starter Battery Pack, Battery Booster, Jump Box, Portable Charger and Jumper Cables for 6.0L Gasoline and 3.0L Diesel Engines

NOCO GB40 to boost your truck by yourself wherever you are with just the boost-block. Also it has far fewer reports of shorting out the truck being brought back to life.

 

That noco fried my steering angle sensor, had to replace the clock spring. Not a cheap part but cheaper doing it yourself. I took the noco out after that

 

we see steering angle sensors die from repeated boosts, not just noco units. It sucks
