jdm2003 Posted July 15, 2017 Share Posted July 15, 2017 (edited) I cant seem to get any PC programs to communicate with my cars ECU. the PC can connect to the ODBII Interface with some programs but never the ECU. sending AT commands from a console through COM seems to get a response when i monitor all (AT MA). i get a data stream from that command I have looked up what consult interface sends to the ecu in bytes. there is an initiation sequence the ecu will not respond unless this is sent. some information is available on setting up the ELM to talk to the JODB Nissan 2003 ecu. but i found it not much help when using a pc program. ECU Initialization Sequence. HEX 0xFF 0XFF 0XEF dose any one know how to send this sequence vi AT commands in a console? lol have attached some information on Nissan consult Consult_Protocol_&_Commands_Issue_6.pdf Generic_Nissan_ECU_Sensor_or_Data_register_table_Ver_2.pdf Edited July 15, 2017 by jdm2003 added documents Quote Link to comment Share on other sites More sharing options...

SpeedyZee Posted August 15, 2017 Share Posted August 15, 2017 Have you got any further with this ? Been a long long time since I messed with OBD commands and the like and my memory is a bit hazy on it now.
