Technical Multiecuscan adapter yellow problem

How did you removed it ? Haven't dammaged any PCB track ? They are very tiny, specially on your ELM !! What is the exact message MES give you when trying to connect? Does it "see" the ELM when you go in Settings / Interface / Scan ??

Regards, Bernie
 
Hi Berni
Removed with forceps R3
Scan interface in MES os OK com7 is detected
Failed connection check serial port Message MES
Thanks
 
Hi Omega22,

use of forceps may have ruined the tracks going from the connector to the CAN chip :-( , if so and unless you're good at repairing PCBs, your ELM is dead..
Regarding the connection, you probably have to modify the ports (COM 7) settings in windows configuration pannel; more likely the speed is not correct...

Regards, Bernie
 
Hello


Still not working

Some ebay link where I can buy ELM adapter for big point year 2007
Thanks

Hola Julio,

between PIC version, Firmware version, PCB version, there is too many possible combinations that one cat wouldn't find her kittys... I really doubt ANY cloner would try to implement the very cheap CAN controler on a PIC chip, so once the "plug" is opened it's quite easy to follow the PCB tracks from the CAN pins to the chip (they're straight) and identify if there is a termination resistor (terminator ? ;-) or not. Some I/F come with an R-C network, which is fine, others don't even have that f** resistor which is fine as well.
But definitely, if one want to connect to other MCU than the engine and ABS (with the yellow plug) this resistor, if present, HAS TO BE REMOVED.
BTW, you'll never know what chip's inside before you open it (after buying, of cource)...

Buenas tardes, Bernie

Hi Bernie,

look at this picture, this is like mine, that it has PIC chip. I thought like you, but some chinese people are good persons and made their products great and cheap hehehe:

This picture if from an Aliexpress buyer, but I can say that is true what this guy says, because I have a few like this one from Aliexpress.

Best regards,
Julio.
 
Can only speak for my Bravo 1.6MJ but that does all the engine things including resetting the oil and service indicators. and using another wire does not work. Only Fiat would make cars operate so differently.

Having done the oil and air filters and oil, I understand why the service cost is so high...... Its over 40 years since I had so much trouble, needed so many tools and made so much mess. Well done Fiat for the staright forward common sense design your are a bunch of stars. (I dont't think!)
 
Hola Hulio,

the PIC actually replaces (mimics) the real ELM327 chip, maybe they spare a few cents doing so ...

BRs, Bernie

Hello,

I think that it is due to vehicle quality, price, and sizes and other stuffs related on physics (ABS/ASR is on other line apart of engine) and voltages (Xenon lights are on other line).

But, as far as I see, I don't think that mixing the Radio and Airbag on the same line is a great idea, I know that the ECU knows what info is more important that other, but I think that it is a bit crappy having human security on the same status as the human entertaiment, on both vehicles. Well done, engineers!

I think that on your case, the problem is the same as us, you need to remove the 121 resistor.

Best regards,
Julio.
 
Agree with that Julio,

be carefull anyway that there MIGHT be more than one '121' resistor ! This number stands for the resistor value: '12' +1 '0', that is 120 ohms, like 472 would be 4700 ohms. The faulty (should not be there) resistor is ALWAYS on the CAN bus lines, on the CAN transceiver chip, pins 6 & 14 of the OBD plug. The recommended termination/filtering should be like in the attached diagram, but would still be ok if there is no RC network...

BRs, Bernie
