Hi all,

I’ve looked online but I can’t seem to find the right answer, I’m hoping somebody can advise me on this one,

I downloaded multiscan ecu on my phone (iOS) and I thought I would see if I could get my Cheap chinese WiFi obd2 adaptor to work on the mrs grande punto 1.2 8v. I didn’t manage to get it to work, I don’t think it’s compatible with the app tbh,

I’ve read online the EML327 works but there’s so many different types,

Could somebody tell me which one would work, I’m just after a wireless one that will work with my phone (iOS) that can read fault codes and reset them as well as ABS and Airbag,

I’ve seen the laptop versions (red,green,blue adapters etc but I’m just after a wireless one that will just plug in and work,

Regards
Chris

I use a laptop...

Have you used the forums SEARCH ?

My GUESS would be that 'torque app.'
And similar use the same kit..??

I found this:

https://smile.amazon.co.uk/gp/product/B07H982HVS/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

the most stable if you can find one and very cheap. Note the use of 'most' as I moved onto a laptop & leads too.

Don’t think you can get that app for Apple devices,

I have a similar device but it doesn’t work with multiscan ECU

I want one that will work with multiscanECU software,

The device I have works with the car with other apps but only reads engine codes not airbags, ABS , or body,

Multiscanecu will do a lot more, I just need to find the correct device

Are we talking about

MultiECUScan ( known on here as MES )

or a similarly named product?

Im talking about a wireless device that plugs into the OBD Socket..

No interest on which app is driving it

Like I say that one worked for me

Yeah, I’m using the mobile app version on iPhone, but Need to know what WiFi obd2 devices work that other members have had success using the MES app

Hi Liam,

wi-fi is just a transmission meaning.

Once received on the device, the informations are processed by the software (in case of direct driver like FDxxx) OR converted to a virtual COM port and a serial-like signal.

As I understand, MES can only cope with serial input, being virtual or strictly physical doesn't matter: it just have to listen to the correct port with the correct parameters !
As far as I know, ELM327 based EOBD wi-fi interfaces (OBD reader) don't use direct driver so they should be able to communicate with MES. Other FTDI chip based readers might use direct driver, so MES wouldn't recognize them ...

As per accessing the various Nodes, you'd need to connect to either one of the two CAN buses: this is done thru a wiring adapter (mainly Yellow or #3 on FIATs), doesn't matter which kind of interface you use !

I'll try to make some pics today about my (permanent) setup based on a ELM327 ...

BRs, Bernie

I’ve ordered some adapters ?, ill see how that goes when they arrive

As promised, here are some pics.

The board is from an ELM327 BlueTooth interface. The switch is a tripolar ON-OFF-ON, it selects either CAN bus or turn off the I/F. The diode is the one from the board...

The placement of the switch is dangerous when you have a crash, because your knee can be hurt bad when hitting the switch.

BTW: I did some attempts for connecting a bluetooth OBD adapter with a laptop but not reliable enough.
Also with Android apps like Torque, only connection to the CAN Modules with the green connector were successful. (straight forward connection)

I modified the OBD module with a double changeover switch to be able to the other CAN modules, but transmission speed was to high for the Blue tooth interface.


My conclusion: For MES only USB cabled interfaces will work.

My ELM327 arrived today but I think it’s the wrong one because it doesn’t connect to the ECU,

I’ve got the yellow adapter but I think the reason it’s not working is because I’ve got the wrong ELM327, the eBay listing says ELM 327 MODIFIED DIAGNOSTIC CABLE for use with MULTIECUSCAN FIAT ALFA LANCIA, I thought it would work but after reading on the MES website modified devices don’t work on the Grande, I just assumed it would work because of the eBay description, back to square one trying to find a lead

Hi Chris,

are you ok with opening the interface and "read" the printed board ? Or at least take close-up pictures of both sides of it ... I could then instruct you on what to do to enable the yellow adapter plug, IF you can connect to the ECU !!

I Managed to removed the 120ohm resister, but I’ve now got more problems,

It still doesn’t connect to the ecu but I’ve got more issues, since removing that resister and trying to connect multiecuscan it’s made the airbag light come on and now my maxiscan ms509 won’t read any live data, it powers up and connects, but it won’t read any live data, it used to read all live data before, The car starts but I just can’t get any info now from the OBD port, would there be fuse that I’ve blown Causing this? Because there is power to the obd and pins 4&5 do give a ground, I just can’t communicate with the ecu at all now,

I’m going to disconnect the battery for a few hours to see if that solves it

Hi Chris, how did you "manage" to get the 120Ω resistor off ? Are you sure it was the right one ? You might have dammaged a PCB trace ... Didn't took any picture ?

BRs, Bernie

Hi Bernie,

My camera isn’t good enough on my phone it just comes out blurry, i don’t think I damaged any of board, I managed to get the resister off,

What I done yesterday was I used a program called EasyObd and the ELM327 connected fine without any issues and I could view some of the vehicles info, but soon as Use MES Thats when the connection problems start

Tried again today but I tried using a different Colour adaptor, I thought I would try the scan option on MES and I let it run to 100% and that’s when the airbag light came on and is now permanently lit, I’m now concerned About why my ms509 scanner doesn’t show any live data neither does EasyObd, EasyObd wont communicate with the car now since doing a scan with MES,

I’ve tested pins 4&5 and there ground
Pin 16 is 12.7v permanently, so the fuse must be ok?

I just hope I haven’t damaged anything, I’ve disconnected the battery and will leave that off until tomorrow hoping it will resolve the communication issue, I doubt it though

ELM327 is kind of a passive device; the 12v input voltage is internally regulated to 5v to feed the µchips and other components so IN THEORY it shouldn't send more than 5v to the CAN pins which (both A-B and L-H channels) are the only ones connected (beside power) on GPs.
MES requires only the yellow adapter or direct connection, maybe by trying other color adapters you unluckyly sent 12 volts where it shouldn't :-(

BRs, Bernie.
