Team-BHP - OBD (On-board diagnostics) for Indian Cars

I have an old ELM327 (fake, according to apps that check for the authentic ELM327 protocol). It did provide some basic data to Torque app.

I wanted real-time ATF temperature, but neither Torque nor any other app could read Suzuki specific details for my ASTAR AT.

Today, I found another SUZUKI SPECIFIC app called SZ. This seems to have a special section for AT/CVT which has the transmission temperature listed. BUT it does not accept my fake ELM327, so can someone suggest a reasonably priced OBD II scanner that the SZ app would be able to use?

Those who have ELM327 devices - does your device pass the genuine ELM327 test?

Can anybody suggest OBD for Baleno please. Is the ELM327 good to go ?
please advise.

I bought it last week and have installed it but could not use it much.

However, I bought it on the recommendation of a fellow Creta owner who is a very frequent traveller and a senior member of our Creta WhatsApp group.

Based upon the features it offers its worth the money spent.

I will also try to use it and will share my feedback.

The one I bought is this one:-

Fits neatly into the port as well.

Got the package but ended with a disappointment. My Android headunit is not recognising the device. Android mobile does recognise though. I might return the product.

Have returned the device.
I also spoke with my Android headunit makers (woodman) who stated the OBD devices may or may not work with the head units. My search continues.

I guess you can only use these devices while they are paired with your android phone through Bluetooth and not through the Head Unit.

Please correct me if I am wrong.

Mine is a 2010 petrol Altis, the one with the old 1ZZ FE engine. Now as I understand, this is the old engine but with some tweaks and modifications to the ECU. I had purchased the super mini ELM327 v1.5 but could not find success. I read on another thread that for the Corolla 1.8 petrol, the adaptor should be "ELM327 v1.4" instead of "ELM327 v1.5".

Whether using the v1.4 hardware would work or should I give up attempting to connect with ELM altogether?

Outside of Team BHP, few sites say that my Toyota cannot be read with OBD II compliant scanners while some say that 1996 onward, Toyota are OBD II compliant.

Since I am using an Android head unit already I thought it can be paired. Many Android head units are moving towards this functionality so that everything is displayed in one single unit. I also had plans for TPMS but looks like I need to do some research before going ahead.

One must remember that most TPMS work on BLE i.e. Bluetooth Low Energy and so your Android head unit must have BLE capability for the TPMS to work. It is a simple matter to install a BLE checker app on your head unit and confirm that it does have BLE capability.

Most ELM327 devices have limited access to the ECU of vehicles (specially older models). I would suggest a wired diagnostic tool like Autel, Launch or Topdon. These are a bit expensive but they precisely diagnose most vehicles and more importantly can reset most fault indications. Most cars have multiple ECUs where the safety devices (belts/ABS/Airbags) have a separate ECU which cannot be diagnosed by ELM327's. When I had a blinking airbag fault on my 2009 City I went to an authorized center who quoted a bomb for just diagnosing the fault. I then purchased a TOPDON diagnostic tool and it clearly indicated the fault as 'Front Right Impact Sensor". I just took the help of my regular mechanic to trace the sensor which was near the headlight. It happened to be just a loose connector. A clean up with WD40 and plugging in of the connector set it right and probably saved thousands.

That is correct and Autel is the most perfect choice for the older Toyota. However the ELM website says that the ELM327 v2.1 is the proper device for reading ECU with ISO 9141 2 protocol. One of my clients having the Corolla (not the Altis) confirmed having better data out of the v2.1 update.

I therefore ordered the v2.1 device on the day of the recent Amazon sale, which is due to be received later today. My earlier device was v1.5
