fetch-toyota-service-manuals

Downloads PDF versions of Toyota Service Manuals from TIS.

Bought a 48-hour subscription to Toyota's Service Manuals (Tech Info) and want to save manuals permanently? Here's the repo for you.

These manuals are copyrighted by Toyota, so don't share them!

(I've also written a Ford manual downloader, available here).

Usage

Set up Node and Yarn

If Node.js >v16.3 and yarn are on your system, skip these steps.

1. Install Node.js 16.3 or newer (with corepack)-- you can find instructions for your OS on Google. Generically, Windows users should install either in WSL or via https://nodejs.org, Mac users should install via Homebrew, and Linux users should follow instructions online for their distro.
2. Run corepack enable-- this gets Yarn working.

Get code and dependencies

Since this project uses Playwright (a headless browser interop library), we'll need to run some special setup steps.

1. Clone this repository to your system with git clone https://github.com/iamtheyammer/fetch-toyota-service-manuals
2. Move into the new folder with cd fetch-toyota-service-manuals
3. Run yarn to install dependencies according to the lockfile.
4. Run yarn playwright-setup to download and set up Playwright (this is important!)

Get your car's manual IDs

1. If you haven't, purchase a TIS subscription from here. The 48 hour subscription is fine.
2. Once purchased, sign in. It can take a minute or two for your login to start working after purchase.
3. Click the TIS tab at the top left of your screen.
4. Select your car's brand (Toyota, Scion, or Lexus), model, and year. Click Search.
5. Click the RM (repair manual) tab.
6. Click any document that appears.
7. In the URL of the pop-out window, copy the RM12345-like code. The full URL should be something like https://techinfo.toyota.com/t3Portal/resources/jsp/siviewer/index.jsp?dir=rm/THIS IS THE CODE&href=xhtml/.....
8. Save this code for later-- you'll need it!
9. Close the pop-out window, and go back to TIS.
10. Click the EWD (electrical wiring diagram) tab. The full URL should be something like https://techinfo.toyota.com/t3Portal/ewdappu/index.jsp?ewdNo=THIS IS THE CODE&model=Prius...
11. In the URL of the pop-out window, copy the EM12345-like code.
12. Save the code for later.
13. If you want diagrams for more cars, repeat those steps for each car.

Decide if you only want your model year's pages

For non-electrical manuals (IDs that start with RM or BM), this tool supports only downloading pages pertaining to your model year of vehicle. Some Toyota vehicles, like the 4th generation Prius, have the same manual ID for every single year this generation of the Prius was made.

To avoid downloading pages for a car you don't have, you can specify the model year by putting it after an @-sign. For example, to download RM12345 for the 2016 model year, you'd use -m RM12345@2016.

There is no harm in doing this for cars that don't support it (the 2015 Prius is an example). The tool will include all pages for manuals that don't support this functionality. There is also no harm in adding a year to other manual types, but it won't do anything.

And, yes, you can specify a year that the car wasn't made in-- but, if you do, the tool will exclude every page.

Download your manuals!

To download manuals, run yarn start -e YOUREMAIL -p YOURPASSWORD -m MANUALID -m ANOTHERMANUALID -m ... with the manual IDs replaced with yours. You can use -m an unlimited number of times.

The script will automatically log in as you, read each manual's Table of Contents, and download every page unless you specify a year-- see above.

DO NOT log in to TIS while the bot is downloading. TIS enforces a one-session-at-a-time policy, and if you log in while it's downloading you'll have to start over. If you know what you're doing, you can use your browser Cookie to log in instead of your email and password. See the command-line options for more info.

Manuals take a while. It can take upwards of an hour to download manuals for a single car. If you're downloading multiple manuals, it can take a long time. Be patient. Stay connected to the internet.

You can find your downloaded manuals at manuals/MANUALID.

Results

This bot downloads all manual IDs you specified. It supports manual IDs starting with RM, EM, and BM.

Electrical Wiring Diagrams (manual IDs that start with EM) have three directories: routing, overall, and system.

• overall contains traditional wiring diagrams (often PDFs)
• routing contains diagrams showing wires' locations around the car (often SVGZs)
• system contains traditional wiring diagrams (often SVGs) - often, these overlap with overall, but not always

Other manuals contain all files from the manual, in a tree-like directory structure that mimics the tree view on the sidebar of TIS.

For example, if a manual page is at Engine-Hybrid System -> 1AB-CDE COOLING -> COMPONENTS, you'll find its downloaded equivalent at manuals/MANUALID/Engine-Hybrid System/1AB-CDE COOLING/COMPONENTS.pdf.

For non-electrical manuals, you'll see two "toc" (table of contents) files. toc-full.xml contains all of the possible pages in the manual. toc-downloaded.json contains the filtered version, if you filtered by year (if you didn't filter by year, it contains all pages). This is useful if you want to see what pages are available for your car (xml) or what the bot downloaded (json).

index.html and toc.js files are for the Manual Locator.

Using the Manual Locator

Sometimes, a procedure will link to another with a blue "INFO" button.

You can use the Manual Locator HTML page to find the page for that procedure:

1. Open index.html in your browser of choice by double-clicking it.
2. Copy the link to TechInfo from the "INFO" button. Often, you can right-click the button to see the link.
   • If you can't, try opening the PDF in Chrome-- drag it into Chrome from your file browser-- then right-click and "Copy Link Address".
3. Paste the link into the Manual Locator.
4. Press "Go" or hit enter.
5. The requested page will open in your browser.

Pages that had a double quote in their name may not work.

This will only work if index.html is in the same directory as toc.js, and those files must be at the root of your manual directory. (If you don't move any files after downloading, this should be the case.)

• To use cookie-based authentication, copy the value of your Cookie header when visiting a manual page. If you're not sure what this is or how to do it, just use the email/password authentication method. When using cookie-based authentication, you don't need to specify an email or password, and your session will be preserved on the browser, so you can use TIS while the bot downloads manuals.
  • If you're on a POSIX system, consider wrapping your cookie string in single quotes to avoid the shell interpreting it.
• Headed mode is not recommended for use. It requires the device you're using to have a display, and it's slower than headless mode.

FAQ

Questions I think someone might ask, not questions anyone has ever asked before.

Why does Node spit out a certificate warning?

You might see a warning like the following print out after Logging into TIS...:

(node:94450) Warning: Setting the NODE_TLS_REJECT_UNAUTHORIZED environment variable to '0' makes TLS connections and HTTPS requests insecure by disabling certificate verification.
(Use `node --trace-warnings ...` to show where the warning was created)

Node.js doesn't seem to accept Toyota's SSL certificate, so this is required to stop Axios (which is used for login and downloading EWDs) from failing every request.

Which vehicles does this work with?

All the ones I've tested. Just for fun, I tried:

• 2005 Prius
• 2015 Prius
• 2017 Prius
• 2021 Tacoma

All worked flawlessly!

How do you avoid the one-session-at-a-time requirement when using Playwright and axios?

Long question, short answer-- I copy the cookies from Axios (which captures them using axios-cookiejar-support and tough-cookie), then import them into Playwright when creating the browser session. See src/index.ts to see the cookie-copying code.

Since they're the same cookies, Toyota sees it as the same session.

You can use your browser's Cookie header to log in instead of your email and password, but only do that if you know what that means. See the command-line options for more info.

Why did you make this?

I wanted to have the manual for my car, and I bought the subscription hoping to download a PDF, so that's exactly what I did!

I saw (and took heavy inspiration from) other projects on GitHub, especially threadproc/tis-rip. However, no other downloader put the manual pages in a tree-like directory structure, tis-rip required chrome-driver, which can be inconvenient. This downloader also works fully headlessly, and you're required to manually log in when using tis-rip.

The code doesn't look that great

Yeah, this was a quick weekend project. Feel free to make it better, though!

Why do you fetch pages one-at-a-time?

Two reasons. Firstly, I don't want to DDoS Toyota. Secondly, it was easier to code synchronously as the function for fetching and saving pages is recursive, meaning I'd actually have to think to parallelize it.

Is this the same code as your Ford downloader?

No, but a lot of the code is shared and similar. Unlike Ford, Toyota actually seems to require session cookies to download manual pages, so getting HTML files with non-embedded images isn't very helpful. This downloader PDFs every page before saving.
