Im working on a project that sends out CAN messages to a micro board and it uses a number of different message types that get specified with the CAN ID. The problem that i am seeing is that when using some CAN ID's i dont get a response when i should.

For Example
How I am breaking down the extended frame ID to use with a project

Priority Subsystem MessageType
00 8C 01

1008C010 no DLC Does not work should send data back

Priority Subsystem MessageType
00 8C 02

1008C020 Does work sends data back

In fact all time when using an even numbered "Message Type" within the ID within the CAN ID the message will work and any time an odd number is used it will not. What might be the cause that something within the CAN ID is getting mixed up. Could having an odd number cause some sort of bit shifting in which the micro board i am writing to does not get the same CAN ID that is sent to it.
