Hi All
Anyone using an OBD2 Bluetooth Scan Tool (dongle) For Android, and do you leave it connected all the time?
I have an expensive tuner/reader that I don't want to carry in the vehicle and have read the info from Ron N (very helpful) on an earlier topic re Kogan one. The phone apps put a new dimension for info if you want it such as when an ECM light comes up.
Cheers

I tried using one back in 2015 to read the ATF temperature. It ended up causing the ECU to bring up warning lights indicating the the ATF temperature was high. I then fitted a Scangauge II and have never seen the lights again.
The SC II might be expensive but it works very will. I use it to display -
1. Speed which is 100% correct matching the GPS.
2. Voltage
3. Coolant temperature
4. ATF temperature.
As mentioned, some of the Bluetooth dongles can play up with the ECU.
If it works and does not cause any problems, there is no reason why it can not be plugged in all the time, my SC II has never been removed since 2015.

I had a similar issue on a 2011 Toyota 79 series cruiser where the glow plugs wouldn't work with OBD dongle connected. I have a other people with this on LCOOL

Yes, I have heard of a few (not many) that have reported problems, I was using a ELM327 dongle.
I believe that the WIFI ones are more reliable - try this one from Jaycar
OBD2 Wi-Fi Engine Code Reader for a little more money $35.97 but then you have a more reliable product.

There are a number of long threads on the Pajero
forum regarding OBDII dongles, codes and issues. Basically cheap eBay readers give issues. The Jaycar dongle doesn't seem to give trouble. The WiFi device has been discontinued.

From what I understand, ELM 27 GENUINE chip devices are ok. Most called Elm27 are copies of chips from, you know where the Virus started, it appears most sold are not the genuine ELM 27 chip being used although claimed to be, and those can cause spurious signals and strange happenings.

There is a very good article on OBD2 in the September edition of the electronics magazine "Silicon Chip." It also stresses the desirability of getting a trader with a genuine ELM327 chip and not a knockoff copy of that chip.
As a bonus, if you get hold of the mag, it has a detailed article on 5G Mobile Communications.

Thanks for
the tip Peter. I usually look what articles SC has but our local paper
shop is out of action due to the pizza
shop next door being fire bombed!

I've the dongle sold by Jaycar, matched with Torque Pro. No issues leaving it connected in the Pajero. Have read that some of the cheaper eBay dongles drain
battery power. Some apparently auto power down, the Jaycar 'Response PP2145' manual specifies the standby current as <40 mA. After greater than a year of use it did throw an ECU comms error code (cleared using Torque Pro), this is apparently a known possible issue and is solved by setting the comms protocol rather than having the reader autodetect. Torque Pro also allows for custom PIDs to be created. Lots of config and custom PID codes on the Pajero
forum, presumably other vehicle specific forums as
well.
PS: I had the vehicle sitting in the drive way for 19 days over summer with no issues, the battery was a 6 month old N70 Yuasa though.
