Good find. Customer s have no clue what we go through to fix their vehicle 😂. As we move into the future guys like us will rule. Not enough competent techs and way too many hard problems to fix with all the crap and wiring on modern cars. I have customers that have multiple trips to dealers with no results for warranty work.

I got a lesson in solenoids with a fuel shut off solenoid. They have a pull in wire a hold in wire and a common. I wired up pull in and it smoked the solenoid in about 4 minutes. It was after that I figured out what the other wire was for.
Definitely a remote start. Press lock, lock, then press and hold lock and the truck will start. Thanks for not trashing the aftermarket like many techs do.
Lots of toyotas have the immo box behind the glove box. The key'd ignition has a "transponder key ECU" behind the glove box on this truck. I would imagine if it were keyless entry with push start, it may have used a different harness to go to a different keyless immo module, and that's why the wiring is like that. GREAT VIDEO AS USUAL!
Another very sharp diagnostic, Jake! I immediately thought: another aftermarket capacitor 🙂 But you also said, in previous videos, this can be caused by water corrosion inside a connector (it takes much less current to hold a relay on, than to energize it). Good job!
Yeah I’ve seen as little 1.25 volts hold a relay closed on an F150 from water in a connector causing a battery drain. I would say that they could improve relays to prevent this but that would also mask some issues that would only get worse over time anyways.
I have seen more of this with sunroof vehicles and high humidity inside and attacking the metal and it not being gold plated and mainly copper it will corrode like a real copper penny with moisture and oxygen. I use rust remover which is a acid and clean connections and then coat heavy with dielectric sprays and dielectric grease to smoother out any air or humidity to connections. Becoming common with price of gold and not making gold plated connections much anymore.
Water sources, sunroof clogged drain, windshield leaky seal, damaged inner wheel well plastic allowing tire thrown water towards the A Pillar behind the fender which then leaks into the door harness passthrough to the footwell area (some makers have blocked this pathway), and the roof factory seam to the side metal of the vehicle under a piece of trim will corrode and leak down the side of the window frame towards the A Pillar with the same results. Looking for other corrosion in the footwell or the inner dash sheet metal structure along the firewall leading back to the root cause of the leak and you will find it. Many EURO vehicles are known to pool up water in front of the firewall when the cowl breaks and does not drain water away properly and corrosion takes over to allow water into the cabin areas, cheers. I am binge-watching your channel right now based on how many useful videos have backlogged based on the TITLE of the videos, 5 of 7 this time, 5 minimum is required for me, and wonder how many more key or corrosion videos are coming, OMG, thank you Jake for all your stuff.
Very nice diagnostic,I have. The same problem in Toyota Tundra,that drain the battery and keep running key off,also don't cranks or crank don't start random when rain or take it to the carwash...in the same conector I found water and green corrosion,I add dielectric grease and now it's been working for 6 months without problems,the truck was from Atlanta Georgia ...
@@agoodneighborautorepair2176 Do you think there is an open weld spot in the frame/body somewhere letting water in? I always wonder with each case like this where its coming from.. bad door seal, window seal, etc...
@@alanw5879 a crack in the top driver side frame is very possible like in the new 2023 Chevrolet silverados that affect the ground in the top left corner of the frame by corrosion of the ground(loosing comunication of radio,gauges and power stering performance..
@@agoodneighborautorepair2176 Did this effect the 2022 Silverado's? I had a friend that had a 2022 that only had 12,000 miles on it when he took it on vacation recently. He was about 120 miles from his destination when a bunch of lights came on the dash and he lost power steering. He made it to a Chevy dealer where he left it for a week. They replaced some harness that said would fix the issue but it didn't. The truck was still not fixed when he was coming back from vacation to pick it up. The dealer said they didn't know what was wrong with it and it could be weeks before they could get it fixed. He ended up trading it in on a used Dodge TRX that they had that had 16,000 miles on it. It turned out to be an expensive vacation since he had to give an additional $22K for the TRX. He always wanted a TRX so I guess it worked out.
Being someone who worked on a lot of Toyotas , I’d always start on those corners for corrosion before i do anything else , cuz if seen it alot , good job though thank you
interesting and it’s very easy to go buy what you have found in the past . i have definitely done it chase a fault that i had had the week before to find similar issue different cause . but like you say back to service data, how does it work , what does it need , what’s missing , or in those case what is there when it shouldn’t be . damm green crusty’s can definitely cause some of the most interesting faults i have come across 👍
Jake nice find . I guess after watching a lot of these strange problems I would start looking for electrical add one then break out the wiring diagram and check connectors for corrosion . At least the visible connectors. Thanks for sharing . 👍
Nice video and diagnosis. I guess the green crusties strike again. Could it be condensation from a wet floor mat? That’s all I could think of since there wasn’t an obvious water trail.
Jake!? You have some luck with corrosions in connectors due to moistuer / water intrusion LMAO... Great video Bro, I was especting a bad ground somewhere...LoL
Ignition always should fire before TDC. So the data pid is always referring to timing from TDC, sometimes the pid will be labeled ignition timing which will be a negative number or ignition advance which is positive number but advanced timing is still before TDC so it’s actually a negative number.
The engine would turn off because the voltage drop would increase to a point the relay would let go. The main reason the voltage would drop is because the circuit that enables the alternator to charge is turned off.

Corrosion. Now. How did that corrosion get there? HMMMM.
Possible leaky windshield?
have a customer with a F150 you have to unplug abs to shut it off
No such thing as luck in this game, your diagnosing skills found it.
What brand is that red flashlight...milwakee or snap on🤔
Lumistix I believe
