Hi,
I am looking for information about how to initiate transmission with MAZDA ECU (DENSO RF4S) with DITD (diesel engine).
There is a obd2 conenctor with 4,5,7,16 pins. So it looks like ISO9141-2 protocol. But ELM327 interface is not able to start communication. Maybe someone has any knowledge how to force this ecu to start communication via K-Line?
There is no information about protocol and obd2 support.
I tried to set x33 (5baud) or x00 (5baud) to wakeup ECU but no replay.
Kind regards
Marek
ps. in attachement you can find the ECU modue. Any hints or tips are welcome.
