I had started a project that would use an Arduino to access the ALDL and display on a touchscreen in the car. The touchscreen is installed in my car and is setup to replace the Idiot lights (Brake, SES, etc). I thought adding the ALDL data would be nice. however I know I need to silence the CCM/BCM to display data. This would not be a logger as I have ALDL Droid and TunrePro for that. this was more for info since I have the screen..
Anyway I captured the data chatter prior to connection for the ALDL diag commands and I cannot seem to find all the info. Here is a snippet of the code
This repeats. I found the CCM Broadcast info, however I have not found the other command.. any ideas? I do know the command starts with the 0x40 and the Checksum is the 0x96Code:10 590A 4100 004C // CCM Broadcast 4055 6B41 6100 0F00 4146 019E 0FCF 7A00 3B96 // Command from? 10 590A 4100 004C // CCM Broadcast 4055 6B41 6100 0F00 4146 019E 0FCF 7A00 3B96 // Command from? 10 590A 4100 004C // CCM Broadcast 4055 6B41 6100 0F00 4146 019E 0FCF 7A00 3B96 // Command from? 10 590A 4100 004C // CCM Broadcast 4055 6B41 6100 0F00 4146 019E 0FCF 7A00 3B96 // Command from?
Car is a 1990 Corvette ZR-1. I have attached the ALDL Streams, A111 and A114 for this car
if that info is useful I might display it as well, I just need to find out what it is
THANKS!!!
