Hello everyone! Some time ago I started with a project, reading data from the ECU and displayed on LCD. To establish a connection between the ECU and Pic controller / 16F886 / use Si9241 / K-line interface /. My Car - Honda Accord 2001 engine D16B6, which has a 5 pin diagnostic connector. I read that communication using ISO 9141 interface, but can not establish a connection between the ECU and Pic controller. Use the 5 boud initialization / 1 start; 8 data; no parity; 1 stop /, then switch to 10,400 baud rate, but I get no response from the ECU. Do not know if I'm wrong in initialization, or maybe not the right protocol - ISO9141 /or not using the correct baud rate/. I do not know if I use the correct pins on the image below.
I would be grateful for any assistance.

Attach wiring diagram and photograph of the 5-pin connector.
