I am a new CBT user. I just hooked my CBT to my vehicle (2006 Subaru B9 Tribeca) today. I have successfully done some sniffing of the CAN bus -- I haven't started analyzing the data yet.
I was also hoping to be able to read the bus between my audio unit and the in-dash LCD unit. I believe I have tapped the right wires, but the CBT is not getting anything. Can the CBT read data on an IEBus interface? The in-dash unit receives the data via a HA12187FP IC (datasheet: http://documentation.renesas.com/doc/products/assp/rej03f0131_ha12187fp.pdf) which is why I'm guessing it uses IEBus.
