WEIRDEST Toyota in the WORLD?? (Part 2 - Flashing CEL, Clicking Dash & Display, Wonky TEMP Gauge)

Now that we have collected some good DATA on the SYMPTOMS of the Crazy Ghost living inside this 2004 Toyota Avalon, we have to look at Wiring Diagrams and see how in the world these issues could possibly be tied together:
-Stall/stumble on Cold Start
-Clicking Fuel Pump Relay
-Flashing/flickering Check Engine Light and Low Fuel Light
-Transmission Solenoid Code
-Flashing Info Display
-Wonky Temperature Gauge
Can we nail down the root cause with ONE scope measurement, and maybe fix it No Parts Required?
Or is the WEIRD Toyota hiding more tricks up its sleeve?

This is why the general public needs to wake up and realize that this is why technicians have to charge diagnostic time. As far as Ivan putting his hands on the car and fixing the actual problem, that took a very short period of time. It's everything else beforehand that needs to be accounted for as well.

[@nevillegoddard4966]

@@jdtractorman7445 That's right. Ivan may have bumped that loose earth bolt & wires unknowingly during the repair, while he was working on some other connector, which temporarily connected the wires back to earth. This would mislead him to think the connector he was working on was the problem. A minute, an hour or a month later some random bump or shake of the would dislodge the earth wires again, & the nightmare on Avalon Street returns!😮

The ship owner agreed, and the old tech took his tiny hammer and tapped the engine and it sprang to life, The customer got his bill which read $5K for diagnostics $20K for knowing where to tap it at.

[@herbieschwartz9246]

Reminds me of the story where a man brings his car to a shop to fix a problem. He returns later and the mechanic says "that will be $100". The car owner asks what the problem was and the mechanic says the he "needed to replace a bolt that had fallen out". The owner asks sarcastically "$ 100 for a bolt ?" The mechanic replies, "No, $1.00 for the bolt and $99 for knowing where to put the bolt".

[@PineHollowAutoDiagnostics]

Hey Dave glad you are enjoying the case study mysteries! Yes this Toyota has several problems hiding under the hood 😉

[@truracer20]

Anytime you have multiple electrical symptoms look at grounds first. A prior repair which solved the problem for a period of days involved a ground. What I see is automotive electrical systems getting more complex and mechanics/"technicians" get overwhelmed and miss the basics. While I'm all for the diagnostician aspect of your work Ivan I think using this approach for a training example is just furthering that instant trigger that overwhelms mechanics. The basics don't involve a lab scope or a research thesis. A list of what items are affected, a look through the wiring diagrams, a recognition of the symptoms and you'll easily end up in the same place. This car displayed symptoms very reminiscent of some of the first automotive electrical troubleshooting I ever did as a 14 or 15 year old, trailer lighting faults. Hit the brakes an everything except one marker goes out, brake lights only work with parking lights, or in conjunction with turn signals, symptoms changing with every turn and every pothole, etc. In 1990 these systems were the epitome of basic, there was no need to look any farther forward than the 4 flat. This is a lesson that most mechanics have learned but fail to apply in situations like this. Eric O did a video a year or so ago on a Chevy truck that was at a dealership with multiple inoperative modules and they ordered all of the modules then charged a restocking fee because the customer chose not to fire a $5,000 parts cannon, Eric O quickly found a corroded in half main ground strap. Moral of the story is, just because the vehicle has a complex electrical system doesn't mean the problem has to have a complex diagnosis.

[@douglasrudd8627]

There are plenty of other channels with people wiggling wires. This channel is for those who want see lab scopes and research theses.

[@throttlewatch4614]

No dealership No repair shop No tech is ever going to go this in-depth for a car this old that’s why they just replace parts until the problem is solved because no dealership is going to let a tech get paid to sit in a room with a notebook trying to CSI this problem. Ivan is one in a million 7:36

The very rare big difference is Ivan cares and gives the time (being self employed) to care about his customers and their vehicles, most just look for the $$££ and stealerships must have targets to hit forced on them from above...

[@vernowen2083]

Back in the 80's, had a Ford Aerostar that kept burning up the brushes in the blower motor. Electrically, it kept leading me to the ignition switch, which I wrote off as not possible as there were no other problems. After the third time I decided to pull the ignition switch and found the crimp loose, which was causing an intermittent resistive connection. Replaced defective switch and blower motor and it lived happily ever after until the recall notice came for defective ignition switches, which led to a court battle for complete reimbursement.

[@HueToobBlows]

Great find without touching anything on the car in your diagnostics. When you know proper diagnostic techniques, it's incredible what you can decipher. On another note, when you stated the customer had it at another shop and they tightened a ground and it disappeared for a day, that was the first clue of where this would end. Also, in my experience, a problem like this affecting multiple systems in crazy ways is typically going to be a ground issue. I had a customer complain that his windshield wipers would turn on if he engaged his running lights on his boat. There were a couple of other odd things that happened but as well. After testing and checking, I found the main ground wire for the replay box was completely broken off. you might wonder how anything would function. The reason why it still did but all crazy was that the electrical current was dissipated by all the connected grounds at the electric panel, which confused the system and it would turn on random things like the wipers when you wanted the lights. Grounds area very tricky thing but when strange things happen for no logical reason, you can bet there will be a faulty ground somewhere in the system.

[@darrenw2803]

im surprised that a bad ground didnt drain the battery...ive heard of that happening before

[@HueToobBlows]

@@darrenw2803 Not sure how a bad ground would drain a battery. You need both positive and negative connected to complete a circuit and thus drain the battery. If the ground isn't connected, no complete circuit, no drain.

[@TheRealJerseyJoe]

Incredible ! But yeah, bad grounds can be responsible for so many seemingly crazy issues. Data driven diagnosis for the WIN. Well done Ivan, fantastic job as always M8 !

[@truracer20]

This should have been a quick and easy repair for each and every shop that had it. Yes bad grounds cause seemingly crazy issues, that's why when a vehicle presents with seemingly crazy electrical issues a ground problem should immediately be suspected. The clicking relay is KEY! The only cause is a loss of connectivity. What's that mean? Well it's either losing and gaining power or ground. Spread over multiple circuits makes it fairly obvious that it isn't a power feed issue, I could care less if it's a"control" issue, because certainly the fault is CAUSING a lack of electrical control, which only leaves the obvious, a poor ground. Data driven diagnostics in this case overcomplicates the job. Say you're pulling a trailer and notice the lighting is going crazy, do you start the diagnosis at the brake light switch, turn signal switch, parking light switch, or go straight to the trailer hitch and solve the obvious ground issue?

[@johnt.848]

Experience for the win always, data driven research and diagnosis is great if one lacks that experience.

[@lvsqcsl]

I did happen to notice on that wiring diagram that the relay that was at the driver's kick panel that you removed and replaced was included in the path to the instrument display, etc. Obviously, the customer can watch this video and see the amount of time you spent on diagnosing this issue and I know you got paid for it. You did a VERY analytical diagnosis. More than 1/2 the time you seemingly diagnose a bad ground. I've been watching you long enough to know when you would move that gear selector it apparently was supplying a sufficient ground to stop the clicking. I'm sure you've been tempted to claim defective parts and have resisted that temptation. I don't know whose worse about this ground thing; you or Eric. GREAT VIDEO!

[@major__kong]

Loose connections vibrate with rpm, too, not just the alternator. The only thing I would have done differently was to take apart that ground and clean it up. Being loose, everything has had time to start oxidizing. I always carry a stainless steel brush and a small can of deoxit, among other things, in a small kit in my vehicle.

[@htwrk2]

Nice job Ivan! That was neat to see you figure out the problem just by studying the wire diagrams and then confirming with the scope. That problem would have led a lot of technicians down multiple rabbit holes. I sensed an adrenaline rush when you turned on the ignition and watched the scope.

[@ischmidt]

Definitely the greatest scope capture of all time. You could see it changing in time with the relay buzzing and the display flashing. I'd be strongly tempted to preemptively replace that relay, or at least the customer might want to keep an OEM spare in the glovebox to avoid being stranded. Buzzing on and off rapidly like that with a load connected is hard on the contacts.

[@tomgroenbeck7620]

Relays are guaranteed for > 100k switching cycles under full load, and they easily survive that. I was once working on Mercedes modules, because when we developed the module I wanted to make sure the relays don't fail prematurely, so I tested it. When I cut open the housing it looked pretty black inside, but the relay itself worked just fine. Even though the contacts were worn from the current the resistance was still low.

This is the coolest diag ever, Ivan ;-) First firing a shotgun with hail at the problem, and hitting the alternator. After this stepping on the brake and doing an excellent diagnosis that pinpoints the problem. When you mentioned the CEL, It screamed ground problem because these are usually fed by different power feeds on these older vehicles. "You have to understand the theory of operations when things get difficult" is one of my all time favorite quotes!

[@mrjsv4935]

Amazing how crazy symptoms one loose ground can cause. Had once almost rusted through ground wire between transmission and body and it just caused white noise to radio, and suspectidly blew two ignition modules., otherwise the car seemed to work normally. Well digital clock in the dash died around same time, so perhaps that poor ground killed that too. Clock didn't come back to life even after the ground was fixed.

I had something similar last week at work. One of the guys was working on a John Deere Gator, the engine would run fine until you turned on the turn signals. The RPM's would go in cadence to the signals, revving up and down with the signals going on and off. Also had no headlights, they were not working and the lights on the switches would get bright and dim. They asked me to take a look at it, we have no diagrams for these things so I was just going off of what was in front of me. I checked the circuit integrity for the turn signals, all good. I then went to the headlight circuit. I had power were and when needed, then checked ground. I had 9 volts on the ground circuit. I traced the wiring and found a connector that had a power wire and ground wire which where melted together. I cut off the connector and re-wired that and boom, everything worked as it should. It was one of the most satisfying diag/repairs I have had in a long time. Keep up the great work brother, it's nice to see the customers come to you and trust that you will get their car fixed and back on the road.
