+# General Context
+
 SEFMJ Honda protocol running 9600 K-line communication between 2004 Honda ECU and multiplex module within body control unit / cabin fuse box.
 
+Some packets are sent my BCM some packets are sent by ECU. Assumption is that BCM is master thus first packet in the cycle is coming from BCM.
