Doubt change elm327 bluetooth

[panterargento]

Hi all, not being the expert I would like to understand if my interface has the change, as in connection with multiecuscan me displays only the motor control, and for the rest gives me connection failed.
I enclose the photos, maybe some expert I can? elucidate.
Thanks.

if I'm not mistaken it should be equal to the change of the one with the usb, I could be wrong...

You're telling me that it might be already? modified?

Hello panterargento from the photo 29-1 see the chip u4 above, there are J3 8 feet and over to the legs of the resistor R4 controls that, in correspondence with the resistance of the two pins below (I mean the pins 5 and 6 starting from the left side as you did the photo) we arrive to the wires connecting the obd 6 and 14 if so? it was clear the resistance R4 to how I see and 121 ohms identical to the one that I removed I in my usb.

I have done so? and to me, everything works perfectly (well before I saw only the engine control unit) now repeat my was usb but I believe that the operation is the same, then if you take away calmly could you send always put it back in the possibility? does not work

Hello

Doing research on the internet I found a guide for the change and said he removed the R04, and I've done it now, and only now I read your message and I had to do the checks that you have described...patience, I acted on instinct, now I just try if it works, even why? when I removed the resistance and flown away and can't find it the most?...does nothing to the maximum I ricomprer? another gi? changed.
Anyway thank you, you've been very kind, your description ? very detailed. :)
...and if the case ever does...let's just leave v?...

Everything works ok.

Only for ABS, it asks me the adapter, for the rest v? a wonder :D

It asks for the modules that require it, that does not depend on the quality? the ELM ...

Thanks ion, very helpful :cool:

This ? what I did to my elm327 bluetooth, remove the resistor R04.
I hope this is of help to someone who maybe has the same interface.
