Multiecuscan

hello
I have an alpha romeo mito 1.4 155hp
been trying to enter the xenon with the adapter 3 (yellow) and always gave me errors
you know any solution?
greetings

To access the Xenon headlights, aswell as the CAN connections, your adaptor 3 cable needs to have a connection from pin 7 on the tool side through to pin 12 on the car side.
A lot of adaptor 3 cables may not have this, as it was added to the specification for adaptor 3 relatively recently.

So if you have a multimeter, see if your adaptor has the right pins connected - if not you'll either need a new adaptor, or will need to modify it.
If it helps, the adaptor 3 cables sold by Gendan have always had the pin 7 - 12 connection, so if you know anyone with a Gendan cable set, it should work ok with that. (if not, Gendan sell the adaptor 3 cables separately)

hello
these are the ones I have

I also tried to modify the elm 327 and did not work either

If you bought them from Gendan then the right connections should be there, as Gendan's adaptor 3 cables have always had the extra line connected.
It could be worth buzzing out the cable with a multimeter to check all is well though.
What error is it giving you?

frustrated connection.
and proved with one multimeter and it is correct, also modify my elm 327 as the scheme 3 to see if he was working and keeping on saying frustrated connection
