Title: Obd2 readers not working!
Post by: shnazzle on May 30, 2015, 16:50
Does anybody have either one of these two eBay obd2 readers?

Both of them work in our other car, but not the MR2.
Stewart@Boro has used his on my mr2 and it does work. So... It's not the port, it's not the readers it seems because they work in the Audi... What gives!?!

I've spent a whopping 8 quid in total for these two

maybe app settings not scanning for the protocol? or the 8 quid in total?  s;) ;) s;)

I have one that looks identical to the right hand one. Except for the writing. Was an Amazon purchase. £6.
Works fine.
I assume your using the fully paid up version of Torque?
If not give it a try.

Using paid version of Dashcommand, as I have for years.

As I said, it works on the audi... Very odd

get torque lite (it's free) and see if that can connect.

I have done. No dice. Plugged it into the audi, instant connection. Literally the second I plugged it in.

Mine works fine in my mr2, fine in the Nissan, but tried it in a friends focus and didn't work; and my old vectra wouldn't work with it either.

So I feel your pain, I know obd2 is supposed to be a single standard but it doesn't seem that straightforward
Title: Re: Obd2 readers not working!
Post by: Anonymous on May 30, 2015, 21:10
Does it have any leds? If so do they light up ? Once mine was pushing the connector back and not quite connecting, but another connector which was slightly thinner plastic was ok.
Title: Re: Obd2 readers not working!
Post by: shnazzle on May 30, 2015, 23:00
It does indeed have Leds. Can just make out the power one. The other two are dead. Funny thing is that it did work once with  the old one (right one). Just once and never again
Title: Re: Obd2 readers not working!
Post by: Anonymous on May 31, 2015, 08:30
Got the one on the right and it didn't work, I paired it and got it to connect but it set my ABS flashing and lit up the airbag warning light (see vid) I contacted the seller and he sent me another one foc and it does the same.......... [youtube:2izxvka2]H4krMOXU948[/youtube:2izxvka2] if you plug it in after starting the engine the ABS doesnt flash but the airbag light is showing dim all the time.

You pays your money, you takes your chance.......... it cost less than a fiver
Title: Re: Obd2 readers not working!
Post by: Mr X on May 31, 2015, 08:36
are the pins ok on the obd2 socket? first thing it should do is start flashing the bluetooth one. If the light is dim maybe it's not got the correct voltage/earth?

 you get the abs thing because these are generic (mine cheap one did this that i've now replaced) and it trys to talk down the lines toyota use to communicate with the abs ecu. I made a post about pulling the abs pins to fix that.
Title: Re: Obd2 readers not working!
Post by: Anonymous on May 31, 2015, 08:39
If I leave mine in and switch on the ignition, the abs flashes.mi think Scott's does the same, he pointed it out to me  s:) :) s:)
Title: Re: Obd2 readers not working!
Post by: shnazzle on May 31, 2015, 08:40
Airbag flashing thing  is a well known prob. Something to do with the pins and how it scans for an obd2 connection.
But NO connection is crap.

What still puzzles me is why it works perfectly in the Audi
Title: Re: Obd2 readers not working!
Post by: stewart@boro on May 31, 2015, 09:05
The cheap one I bought first from eBay set off the abs just the same  s:( :( s:(

I don't get that either, I've had the same problem though! Ironically the mr2 has always worked though

I have an older  obd2 reader that  did the same and removed  the  two  pins necessary to make it work  and it was fine, I just wanted one of the stubby ones to replace  it, I tried the pin removal and it stopped  the abs flashing  but still  lit up the airbag  light.

I use OBD diagnostic Toyota Pro with mine on my phone good thing is it will do imports as well if you upgrade to the pro version

Post by: 1979scotte on May 31, 2015, 14:47
Are you starting the car with the reader in place?
If i do that with mine it sets off the abs so i always start the car beforehand.

I have this cheap ebay reader. All you have to do is snap off one of the pins. I can't remember which one but it's on this forum somewhere...

Like I said......did the pin removal on the same mini type one but it still shows a fault.

I did do the pin removal back in 2012 with the older one and that was fine, it's just that I wanted the shorter obd2 because the longer one gets knocked out easily if left in all the time.

So basically the key here is that if you want a Bluetooth module to work with your 2, you just need to spend money

Probably. this is the problem with cheap ebay stuff I guess.
But still, I can't say it doesn;'t work, because it does....just not on the 2. So technically it's not broken.

It's like having a knife that cuts through everything but not carrots. You can't say it doesn't do what it's supposed to do. The MR2 is a carrot. Stupid orange legumes.

I use either iphone or ipad and the reader is Bluetooth but as has been said it was an expensive solution.
It is dedicated to the BlueDriver app by Lemur which can be downloaded for free and has limited functionality to read codes but if you want live feeds from just about every sensor and measurement available to the ECU then you have to upgrade.

It doesn't set off any false lights or readings, just a bit fussy about the order you plug in, link and read.

I brought it because it's meant to be faster but it would seem that the protocol is as fast as it's going to be with the cheap ones! I sill only get about 6 reads per second   s:( :( s:(  
However, I haven't found a car this thing hasn't worked on yet!
as a bonus though I leave it plugged in and the thing is so small i don't kick it getting in and out of the car like the other one that's built like a brick!

I have one that looks exactly like that (just with a slightly different sticker on) and it seems to work fine and doesn't cause any flashing lights at all.

Points to consider about leaving it plugged in all the time are that it will drain the battery and could someone hack in or is it impossible to connect without the ignition on?

With my JDM 2003 sequential manual MR-S i can connect the ECU using In Torque the protocol "ISO 14230-4 (5b init, 10.4k baud)" in car profile bottom option and ELM327 custom configuration string:
ATIB 96 n ATIIA 13 n ATSH8213F0 n ATSP4 n 0100
It does allow all readings to work, I cannot however read fault codes, it tells me there is none, despite the engine light activated in the dash...
I even tried the mini vci cable that does work with techstream to no avail... Mini VCI and techstream it is then for japanese MR-S...
