FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

[Alfaeddy]

Hi eddyshow

Which vehicle you would like to read it?

According to your description, it may be just this problem resistor

This Wifi ELM interface I do not know yet whether it is the resistance of R04 in your ELM I can not say
Do something, please make a picture (with Macro) from the board
I can tell you more about this

The user Alfa156sarajevo also has problems with the wifi ELM
although he has a resistor has remove from board

the vehicle is a 2003 fiat punto multijet.
I attach the picture as soon as possible

The user Alfa156sarajevo as solved?

Hello

As far as I know he has not yet found a solution
But he says that he only has a problem with Multiecuscan

With AlfaOBD and ScanMaster should be Wifi ELM works well

But your problem seems that the CAN bus problem in this thread
will be described.

I include photos of the front and back of the interface circuit elm327 wifi.
I hope in you for the solution.

Hello eddyshow

Remove the resistor in the red frame (R04) and your ELM can read the CAN Bus Protokoll

Hi Eddy,

I have ELM 327 V1.5a. I can only read using multiescan, electric steering, gearbox and engine.

I cannot read body, dashboard,abs service and climate control.

What do I need to do on this ELM327 1.5a, in order for it to read the rest of the modules? What do I need to remove?

my ride - Fiat 2006 Grande Punto 1.4 8V.
Thanks...

Hi swatchlu

Remove the resistor in the red Frame ( R04) and you can read also CAN Bus with your ELM Interface

Hi Eddy,
Thank you!

if I remove R04, as mentioned. Will affect the ones that I already can read?

[Alfaeddy]

Hello

No, it changed this what you read previously could not.

Multiecuscan has read these interface problems with the CAN bus
By removing the resistor we the only possible CAN bus the other protocols are not affected

No, still no solution for MES and WiFi.

If somebody else is thinking to use elm wifi and MES I would not advise you to buy it.
Elm WiFI works with AOBD and SM but not with MES.
