OBD-II and SAE J2534 Tools List for PC, Smartphone, Tablet; Toyota centric, July 2018

OBD-II and SAE J2534 Tools List for PC, Smartphone, Tablet; Toyota centric, July 2018

I purchased a 2009 Prius with 74K miles around the end of January 2018.
I've been reading through many of the PriusChat articles and thought that it would be good to collect some of the information I was looking for in one place for each subject.

This is a list of On-Board Diagnostics (OBD-II) and SAE J2534 tools for a PC, smartphone, or tablet that are used to read Diagnostic Trouble Codes (DTCs).

 

Here's a little information for when you buy a device to read DTCs.

There are two types of diagnostic devices to consider, an SAE J2534 interface and an OBD-II reader.
To use Toyota Techstream software, you need a device called an SAE J2534 interface or pass-through. Techstream gives you complete scanning and programming functionality, so it can read all codes and subcodes. Techstream software is Windows only, thus the need for a Windows notebook PC.
For general code reading, you need a device called an OBD-II reader. OBD-II readers will read standard OBD-II codes but are more limited in the manufacturer specific codes they can read, and do not do programming.
They both use the OBD-II connector in your car, but have completely different command sets.

Several target Toyota and hybrid vehicles including the 2nd Gen.
Except for the Toyota Techstream system and MongoosePro Toyota 2 MFC2 SAE J2534 Interface, no endorsements are implied and the ordering does not necessarily imply any preference.
Toyota Techstream is the reference standard to compare to.
If you have the budget and/or need complete scanning and programming functionality, buy the Toyota Techstream system.

Remember, use this as a list, not an evaluation. You'll need to do your own up to date evaluation when you buy an OBD-II or SAE J2534 device. Not an all-inclusive list, mainly includes lower cost devices for PCs, smartphones, and tablets. Does not include handheld devices such as from Autel and Innova.

There are three levels of subscription for the Toyota Technical Information System (TIS) software: Standard, Professional Diagnostic, and Security Professional.
(A Security Professional level subscription is required for car to remote and immobilizer reprogramming or resetting. You must be a locksmith or automotive technician qualified in vehicle security system repair and a current member of the NASTF Vehicle Security Professional (VSP) Registry to purchase a Security Professional level subscription).

Prices may vary, shipping and taxes extra.

(SAE J2534 devices use the OBD-II connector, and are inherently non-ELM327 since they use different command sets)
(Windows versions that are compatible are from website or email response. Which Win version actually works is often "try and see").

If you have trouble with this model:
Measure the resistance between pins 6 and 14 (Wide edge of "D" at top, 3rd pins from left, top and bottom rows). If it is not 120 ohms, return for a replacement until you get one with the correct resistor in it. Some were made with 20 ohms and overload the CAN bus signal.
The problem can also be fixed by removing the 20 ohm resistor.
(Both end nodes on the CAN bus have a 120 ohm resistor across the +/- CAN signals right next to the CAN transceiver pins to terminate the bus).

21. ELM327 Identifier App, Android 4.0-up $0 (Daaren Fonloil)
Use this app to identify the real ELM327 version you have, because a lot of China clone adapters often declare a wrong ELM327 compatibility.
ELM327 Identifier sends almost all AT commands available and shows what are supported in accordance with the ELM327 official datasheet (up to firmware v2.2), so you can quickly check if the adapter declaration is correct or if it's a fake adapter.
Some AT command requires a car connection with specific protocol to work; to obtain comparable results, these commands aren't checked by the app. The number of AT commands checked are 103.
IMPORTANT: a fake adapter doesn't mean that it will not work with your applications.

For those who don't have the time to read through post # 2, here is a summary with recommendations as of this time.

Here's a little information for when you buy a device to read Diagnostic Trouble Codes (DTCs).

There are two types of diagnostic devices to consider, an SAE J2534 interface and an OBD-II reader (OBD is On-Board Diagnostics).
To use Toyota Techstream software, you need a device called an SAE J2534 interface or pass-through. Techstream gives you complete scanning and programming functionality, so it can read all codes and subcodes. Techstream software is Windows only, thus the need for a Windows notebook PC.
For general code reading, you need a device called an OBD-II reader. OBD-II readers will read standard OBD-II codes but are more limited in the manufacturer specific codes they can read, and do not do programming.
They both use the OBD-II connector in your car, but have completely different command sets.

See post # 2 for details and links.

SAE J2534 interface devices are in section I.
Toyota provides the MongoosePro Toyota 2 MFC2 from Drew Technologies, number 2, in their Techstream LITE Kit, number 1, but they are expensive ($500 alone or $1345 for the kit of device + 1 Yr. subscription of software).

For a low cost SAE J2534 device, look at a Mini VCI, number 5 ($35) or 6 ($50).
For a little higher cost, look at the VXDIAG VCX NANO series, numbers 3 and 4 ($80 - $240).
(These come with the appropriate software).

For OBD-II readers, Bluetooth readers will generally work with Android, although there are a few Bluetooth devices listed as working with iOS. Wi-Fi readers are often easier to get working with an iOS device. Software for iOS is more limited.

Avoid the cheap ELM327 clones.
Devices listed as non-ELM, will not run the common ELM apps such as Torque Pro and Hybrid Assistant.

OBD-II readers are in section II.
OBDLink LX and MX Bluetooth devices are highly recommended, number 1 ($50 and $80). They work with the Torque Pro and Hybrid Assistant Android apps ($5 and $0).
ELM-327.EU ELM327 Bluetooth uses the genuine ELM327 v2.2 IC and is also highly recommended, number 2 ($57).

For iOS, look at -
OBDLink MX Wi-Fi, number 1 ($130)
ELM-327.EU ELMINO WiFi, number 2 ($64)
PLX Kiwi 3, Bluetooth 4.1, number 5 ($100)
K Solution LELink^2, Bluetooth 4.0, number 6 ($35)

Software is in section III.
Toyota Technical Information System (TIS) subscriptions have Professional Diagnostic and Security Professional levels, number 1 ($55 2 Day, $1095 1 Year).
Both levels allow use of Techstream scantool software, all available ECU calibration files, and Identifix Direct-Hit, plus access to the technical information library.
Security Professional adds access to vehicle security information, including key codes and immobilizer/smart reset capability. (Before you can purchase this subscription level, you must be a current member of the NASTF Vehicle Security Professional Registry).

Torque Pro, number 3 ($5) and Hybrid Assistant, number 4 ($0), both for Android, are very popular.
Torque Pro has a custom Parameter ID (PID) editor.

For iOS, look at -
OBD Fusion, number 5 ($10), can create custom enhanced PIDs, Toyota Enhanced Diagnostics Add-on ($10)
OBD Auto Doctor Pro for iPhone, number 6 ($23)
OBD Car Doctor Pro, number 7 ($4)
Car Scanner Pro, number 8 ($6), has custom (extended) sensors (PIDs) support for manufacturer specific data - unlimited active custom PIDs

 

They look nice, but they are far above the price range I was targeting. There are a lot of options and companies if you can go to that level.
The MongoosePro Toyota 2 MFC2 in my list is the current version 2.
