Low Mileage Camry What Happened To You? Part 1-The Diag

This is a great educational masterpiece to anyone who doesn't know how communication system works. You tickled every possible spot, Powers grounds, communication lines, canbus lines, gateway module, can junction connectors, datalink. Everything everything.

That dashboard looks like it is in lamp test mode :-) I really value your diagnostic strategy and your effort to explain it, Jake! After you detected the shorts, I was betting on a loom smashed against metal somewhere, but disconnecting the power steering removed the short, proving wiring is OK. Both modules damaged in such low mileage is weird... Hope there is a Part 2. Great video!

[@walterhai310]

Love your videos. You asked about terminal resistance other than 60 ohms or 120 ohms. I ran into a 2014 Honda Crosstour with ADAS issue. After spending 3 hours on the vehicle trying to figure out why the new steering angle sensor circuit is at fault (component internal malfunction) whether it is connected or unplugged, wrong ABS module assembly has been installed due to expensive new unit and used unit was not available. 2012 ABS module was used on 2014 which are not compatible. The terminal resistance on this unit is around 86 ohm. Very interesting. ABS module was disconnected when measurement was made.

Great video. Thanks for your time.

[@ekimbrough1413]

First off. If you can't diag this I seriously doubt the dealer can! Looks like a recall to me! I would have gone to the DTC and did the resistance of the network. Measuring the data packs was O.K. ...but you needed to know whether you had 60 or 120 ohms first. That would've told me that one of the modules was bad, and where the modules are that have the terminating resistors. One would be the ECM/PCM and the other? I don't think there's any way that the PS and ABS are bad simultaneously! What you have there is either short somewhere between those two....or a bad ground where all thiose modules have connection in common! As for the pass through connectors: why the hell did they do that??? THAT'S MADNESS! Your video quality is excellent and being a great adventure through the land of terminal madness! LOL!

[@phillipzan2005]

Yes the Toyota, especially newer ones have very complex networking. But I break it down like this. In your case ABS no communication and also with scan tool. I test like you did at the ABS and then go back to the wiring diagram. When I get to the junction connectors of the diagram, I just pick a circuit that is tied into the ABS and see where it leads. So for example the steering sensor is tied into the ABS. From their I see "Well can I talk to that module or is any other module complaining that it can't talk to that module?" If the answer is yes, I move on. If the answer is no, I'll go to that component and test there. With the connector plugged in and unplugged afterwards, because a bad module or sensor could be bringing down the network. From there depending on what I find I just work the checklist. If all modules test out good, well it is time for some ohm checking(yes I know that sucks and be very time consuming to do) and maybe jumpering wires afterwards. Last thing I will do is short to ground/voltage and Terminator resisting check. Usually at that point that will give me direction. Definitely one thing with complex networking is I ask 21 questions to the client to help me pinpoint where I may want to start looking after studying the diagram. Also if anyone is curious, pretty much all the Gateway Network Modules are in passenger side behind the glove box. Good video sir.

[@imfloridano5448]

Why the manufacturers don't make diagnostic software that puts individual modules in a loop so the output can be compared to manufacturers designed signal outputs. Basically it loops the module to check all signals, voltages, and grounds. Knowing the correct frequency and voltage output would be very helpful along with placing them on the schematics and wiring diagram. You don't know if you should have 3.5vdc or lower as an output. The assumption is a 5vdc output similar to the reference voltage

[@autodiagyt]

Toyota actually does a great job of telling you in service information what a wire should have. Its call Terminal of ECU just find the document for the module in question.

[@DuaneDonaldson]

Very rare blown fuse for no reason, the fuse itself terminals are corroded or corrosion has crept up into the fuse package itself and can carry enough mA to light a test light but not enough Amps to power up the entire circuit. I have come to a point in life that while doing my initial test to see that certain systems or components are not working based on feedback from the scanner and DTCs, I then do my non-intrusive visual inspection AND I swap out the fuses and relays ASAP then double check if anything came back to life while looking at the fuses for said corrosion and can bench test the relays later. YES, I know that playing with fuses and relays may also jar the fusebox issue back to life, is it the socket I just touched or another issue under the fusebox. It does not matter, can I do a wiggle test to get it to act up again, or after a few test drives or a humid day will the problem come back again. If no problem after a few days, I can give the car back, I don't need to give it back tomorrow, I don't need to tell the owner I fixed it in 10 minutes due to a bad relay and corroded fuse guts. I get an hour and I need to verify it was something simple and stupid and can run errands in their car with their gas, no worries. This will not be the only time I work on a 2022 Camry so I will create a workflow and ID the fuses and everything else on this vehicle that will be of importance so the next time I have an ABS issue, I will have at the ready in my library a QUICK REF CHART of this vehicle system that I have previously ID'd all components of interest for speed of diagnostics in the future. OF COURSE, this car will not be that easy. GOT OFF on a tangent about self-problematic fuses, not forgetting fuse terminals that have been pushed down into the fusebox by the owner/mechanic, let's continue watching. Grease smudge = Technician Makeup = a real man with garage camo Toyota connectors loop in and out as these are the disconnect points for testing portions of their CAN System, similar purpose as a STAR Connector or GM COMB Connector but not always in an accessible location. Similarly, the GWM has multiple CAN1, 2, 3, and 4 separated sections, so performing the UNPLUGIT Test at the GWM is similar to the COMB or STAR allowing us to test each leg of the CAN at a single location. The JC Blocks can be the issue if they have corrosion so this would be an expected inspection coming soon. You are seeing that the COMM to the ECU is good and that goes through JC4 but maybe at a connector higher level not affected by the lower level of corrosion, lets see where your inspection is going to lead us? I would not have done the continuity test if I could test for CAN COMM waveform at the GWM Connector to see if a good signal is available at that test point. How much circuitry did you actually test between the ABS & GWM? Did you also test all other circuits for the missing modules on the TOPOLOGY? Did you test for JC4, JC3, and JC2? NO, kind of a wasted test while a bad CAN4 waveform test would dictate us to dig deeper at each leg of the CAN4 COMM different circuitry to narrow down a single pathway/module/short. In this portion of testing, the GWM Connector is your STAR Connector and this is where you found your problem after the requirement to dig it out under the dash OMG. Could we have started at the EMPS with the WONKY Power Steering at the beginning of the video, MAYBE a good idea but with the available info of CAN4 dead via the schematic, EMPS on that circuit, I am not going to be that guy to say THAT IS WHERE I WOULD HAVE WENT ASAP, no, but a good idea with available info after a little homework and its nice that the connector was easily available, easier than the GWM and going straight to the EMPS would have fixed everything else I GUESS? Was the Power Steering a cause or effect?? How is EMPS affecting ABS on the TOPOLOGY, is a certain UCode killing both? I would think ABS would be ties into Power Steering STABILITY CONTROL?? Is the ABS in series or parallel to the EMPS on the way to the JC4, etc? I am not so sure that I trust the MATH setup for the waveform, as we say, know your tools, you know best Brother for your setups. How did it test ok earlier in the video??

[@autodiagyt]

This vehicle was definitely an onion that had to have the layers pulled off.

[@tonyfremont]

Could have been wrecked in the past or maybe flood damaged. Or might be a lemon law buy back, or maybe it was repossessed and then auctioned by the dealership because of all the no comms and dash warning lights. People generally freak out over a bunch of lights, but imo the more lights, the more likely it will all filter down to one actual problem (ground/power/comm) that has a ton of side effects. Im curious why pulling the network spluce pack connectors and looking at each subnet wasn't on the table. Aiui, CAN devices pretty much all will "talk" without being "spoken to". The splice connectors seem like good places to look at the signals of each device; the power steering module should have been fairly easy to spot outputting a mess of a signal. Obviously you cant diagnose every possible network issue from the splice connectors, but you can access several network segments, or devices from one connector. Everyone is different, and im certainly not saying anything was done wrong here, I'm just sounding off on my thought process.

[@autodiagyt]

Just keep watching the series lol

[@philh9238]

Seen a diagnose Dan video about the ohm meter he was checking a wire from end to end it showed good continuity but it ended up being a shorted to ground wire.

[@JessClearyAutoRepairLLC]

@@autodiagyt cool, maybe I missed it on the video, but my last step would be to confirm communication was restored at the abs module after disconnecting the power steering module.

@@JessClearyAutoRepairLLC when I was testing the wires from the gateway to the abs module the proved circuit integrity. I didn’t show where I went back and checked it again after unplugging the power steering but I did double check them.
