OBD2 Bluetooth Scan Tool (dongle) For Android or iPhone

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!

EDS will not read the ATF temperature, well at least on the D-Max.

Correct Kazza055, it doesn't read the ATF temperature, but I have a MM4x4 lock-up kit on the AT, so hopefully high ATF temperatures should not be a problem. Even before the lock-up kit, ATF changes didn't show any burning of the ATF, suggesting that the OEM cooler is doing its job, even when towing.

The ATF won't show any burning unless it is far far far in excess of normal temp. Most discolouration by oxidation and some friction disc material particles in the fluid. Unless the clutches are slipping and generating localized heat far in excess of normal temps and turning the steel plates blue there won't be fluid discolouration or burning to any extent at all. If clutches are slipping the auto doesn't last long. All the autos I have rebuilt had fairly clean fluid apart from some which had the wrong brown fluid in there. Today, often the modern fluids used are not red as people expect.

Be careful with the lockup as any torque more than normal being fed through that little weenie clutch in the TC will destroy it. Often not mentioned by promoters of those kits. It is designed to UNLOCK when asked to transmit any significant torque. The Lockup kit take away that safety aspect.

You don't get the ATF temp as one of the default ECU outputs you have to create a custom PID to retrieve it. See the following thread custom Pajero ATF PID. This is for the Aisin transmission. There is a different code for the Jatco. The OBDII reader referenced with the power down feature is the OBDLink MX+. Avaiable from Amazon Australia ~$150. I'll be sticking with the Jaycar for the moment.

All any of these OBDII devices is monitor the ECU codes so if your ECU monitors the EGT then in theory you should be able to read it. All you need is to know the code to read it.

If your vehicle has an EGT probe in exhaust which is connected to the ECU then possibly able to read it if appropriate entry code is in SC. If there is no EGT probe in exhaust then you would have to fit one so an external EGT gauge can read the exhaust temp. My 2011 Dmax, now fitted with a dump pipe probe does read exhaust temp via a Scintex gauge and it has an alarm feature. If needed, fit a buzzer and set EGT temp limit. Mine set at 450C. Since there is around 200C drop of temp across the turbo impeller as heat energy is used by the turbo action, the temp prior to the turbo can be 650C when the probe 100mm after turbo is reading 450C. Some do fit the EGT probe prior to the turbo, (drilled manifold), that is ok but if the probe fails the bits destroy the turbo.
