I have a 2019 VDJ 78. If I knew where I could purchase a workshop manual for such a newer model, I would. But I have not found any available for purchase or download. If you know where I can obtain one, please let me know.
The truck is new to me so I'm only basing my understanding off of Toyota's website.

Yeah so I went on my site and got that diag table, its in the vehicle brake control section and is the diagnosis procedure for the fault "Slip light always illuminated". IT would seem that if all you did was remove components, a verification of good connections would be in order. You didn't touch the skid control ECU (unless you did more work than was noted) so I wouldn't worry too much about that. Maybe check in the connectors to make sure a pin is not bent, but again that would be fairly odd unless you are not careful at all in your work ha.Thanks for the Slip pdf. So can I assume that this has something to do the the brakes? I will note where you obtained the info (html) and have look.
If anyone that has a newer model can attest to, there are so many connections inside the dashboard with no apparent meaning. I mean just male connections that do not seem to have any purpose. I can only assume that Toyota builds the 70 series with the wiring for every market or possible upgrades. Nonetheless, I will try to locate the SKID Control ECU connector run some tests as soon as I have a chance.
By the way, in speaking with my dealer about where all of the sold 78 have gone (Put Depot), he mentioned Aichi-ken as one place. Have you come across any? A lady was walking by the other day and said that my truck was huge and then asked who the manufacturer was. I said "Toyota"! She couldn't believe that such a HUGE truck could be manufactured by Toyota. The neighbor across the street is envious, but he's a young guy. My truck is very rare where I live.
Just be awake that you will need a newer version of techstream (or else it won't have the vehicle data) which will require a subscription. You also need to purchase from "global techstream" as your vehicle is a "general market" so you cannot use a USA, Europe, or Japan market license or it will not connect. Japan version may connect actually. I just know for grey market vehicles in USA and Europe we have to but single use licenses from the correct region.Update
I took it to the dealer today and they used TechStream to check the truck. TechStream indicated that there is no connection between the ECU and Steering Angle Sensor, i.e., no wired connection. I'm dumbfounded on this. Everything is plugged in and the dealer had no idea other than maybe the Steering Angle Sensor needs to be replaced. This is a new truck and I was very careful in removing the dashboard, didn't even unplug any of the connections to the Steering Angle Sensor. It was suggested that I completely remove the dashboard again and make sure that all of the connections are correct. So that's where I'm at right now, that and I'm going to try cleaning the connections. If that doesn't work, then I'm going to have to order a new Steering Angle Sensor.
I'm a Mac guy, but I've decided that I need a diagnostic tool so I'm going to set up an older MacBook with windows and try to find a copy of TechStream since the Blue-tooth module that I purchased is basically useless.
