The sequence, number and type of tests are dictated by the control module. Operator has to press and hold the brake pedal and then continue. For example, if “Press Brake Pedal” displays, the Some tests display a command to the operator. The tests let you to use the scanner temporarily activate or control a vehicle system or component, and when you exit the test, the system/component returns to normal operation. Typically because the transponder inside the key has not been coded to that particular system.Īctive Tests, also known as Actuator Tests, are bi-directional diagnostic tests on vehicle systems and component.
When a key for a modern vehicle is replaced, the new unit will often turn the mechanical switch but fail to initialize the system or start the vehicle. In addition, it lets you recode the transponder in a
Provided that a module can be re-coded, the device allows for the coding and programming of a replacement control module or changing previously stored incorrect coding as expensive factory tools do. It gives you the ability to ‘flash’ a control unit with new program data. It allows you to recalibrate, adapt or configure certain components after making repairs or replacement. With NT530, the check of electronic components such as switches, sensors, relays, & actuators is made a simple task.

But be wary of damaged stuff, software out of date, subscription lapse, etc.ģ.Foxwell NT530 is confirmed for bi-directional testįoxwell NT530 allows you to use the scan tool temporarily activate or control a vehicle system or component. But my hunch it existed back in the past.Īs for a sub $200 bi-directional unit there’s always used, 2nd hand, Craigslist, etc. Doubt we’d see that proprietary software released. My gut, instinct, view is that way back deep in the Toyota proprietary fortress there was a way to tune these ECM’s. Software liscence infringement? I’m not a legal eagle.Ĭouple customer software shops, HPTuners comes to mind, have been developing front end software to custom tune ECM’s.
#4runner techstream android
Some of the chinesium brand units ( Launch, Autel, etc.) in past years have been bundling up factory auto software on an android platform and selling units. Toyoalta ECUs arent based on an eprom, therefore you cannot reburn/flash the chip.Ģ.Point version of Launch, Autel, etc for bi-directional test However, its limited in the results (typically higher rpm and higher fuel output). There is 1 method of modifying the ecu that does work to increase performance, but you really need to know, and understand, what you’re doing.
#4runner techstream Bluetooth
I have a generic OBD2 bluetooth (and torque pro) for reading generic codes and real time data. that if you want different performance, you have to go with a “piggyback” or completely replace the unit with something that is fully adjustable.ģ) I can’t imagine theres anything better than Techstream for checking and testing components, but I’m intrigued. Looks like the ability doesn’t exist on models earlier than 2001 (though I did see a Chineesium flash tool saying 2000… wonder if they mean a late 2000 model or a built in 2000, model year 2001 though).ĭigging through more pages, I’m finding more and more posts talking about how Toyota ECU’s can’t be tuned. Looking around a little, I see that I’m wrong about Techstream, it can be used to flash/program, just not my model year. looking for performance of one kind or another (most want more power, some want more efficiency/fuel economy). You’re looking to make changes to the fuel/timing/injector maps I take it. It’s a diagnostic tool first and foremost, which is what a Toyota technician needs.īut there May be other “programmers” out there, which would be the bi-directional part. I have Techstream and and about the only “programming” it allows is with the immobilizer and keys. It seems happy with this retirement arrangement. I google search and confirmed you can follow the instructions in this post: I used this cable, which is still available: There may be better methods now, but I know mine works. What it can do on the rather primitive 3rd gen system.
I think you’re referring to Techstream software. I think it is called “Mode $08”, “Active Tests”? A budget Scanner in like the $200 (or lower?)Ĭheap Toyota 4runner bi-directional scanner reviews:ġ.Using experience with Toyota Techstream
Looking into getting one scanner that will actuate various devices. I just want to do things like turn the evap VSV valves off and on, maybe auto bleed the brakes and any other active tests. Car model and year: Toyota 4runner 3rd gen T4Rs
