Help with elm327 and Fiat ECU

[rodrigolange]

Hi!

I need some advice regarding the use of the ELM327 adapter with a FIAT Stilo Electric Power Steering (EPS).

I must connect with the EPS due to a project, and I'm connecting directly to the EPS (I only have the EPS) using the k-line.

When using the MultiECUScan software, i can connect without any problem (it recognizes the EPS and reads data).

But due to the project, I must communicate with the EPS using direct serial communication (for instance, using HyperTerminal). However, I tried lots of AT commands (including ATSP3 to use the k-line and "0100"), and i keep receiving only "BUS INIT: ERROR".

Can anyone help-me? What is the correct sequence of AT commands to connect to the EPS?

Thanks in advance, and sorry my English.

For those who are interested, I was able to communicate with a FIAT EPS using the following AT commands:

atz
ate1
atl0
atib10
atsp5
ats0
atal
atst62
atsh 81e9f1
