I just want to add a little info to this. Nothing truly helpful; just something I noticed. I have a manual base model (no rev matching) and I REALLY want to plot my current gear against other data.

I noticed that in all of my logs that I never receive any messages with id 0x421 (what's supposed to contain this data). Looking at the spreadsheet, I see that this message also transmits the S-Mode status. I remember a post I read a while back about adding rev matching to a base model, and two of the things needed are a gear position sensor and a new ECU. Given that I don't have the proper ECU (or even the actual sensor!), this has to be the reason that this message isn't on the bus. Just a heads-up to anyone with a base model trying to sniff out the CAN bus.

I am starting to use an app called "realdash" for a replacement gauge cluster in my Z and have been looking into the canbus as well. I have found most of what I need but I was wondering if anyone has been able to get the message for blinkers left/right, e brake warning, and door ajar? Also, has anyone been able to pop the trunk, roll windows up and down, or alter AC systems through canbus? Thinking about running a tablet in the center with the realdash software with a custom template made only for the above car control functions.




Thanks in advance,

Very nice. I've not seen that before.

You might find this project interesting:

This guy used an Arduino to talk to the canbus and wrote his own Android app to talk to that and control the HVAC.

I'm looking to do something similar myself.

The HVAC won't work on the base model unless you swap out the control unit because the base model one doesn't have canbus control.

I don't mind swapping the module if needed to talk AC via canbus but not sure what the commands are for the AC. They don't seem to be in the system.

The signals for blinkers, doors, and ebrake should be in the spreadsheet under the BCM.

Unfortunately I don’t think you can control anything over CAN because the input switches go directly into the BCM and not over CAN, but I could be wrong there

02 10 c0 00 00 00 00 00
Enter the diagnostic session that allows us to issue service 0x30 requests (which allows commanding of the BCM)

02 3e 80 00 00 00 00 00
Tester Present. I'm sending it periodically every 2.5 seconds to keep the ECU from dropping out of the diagnostic session that I put it in.

04 30 05 00 01 00 00 00
The command to lock/unlock the doors. He's explained in the blog and in this thread what the parameters to this command mean, so I will not repost
all of that

Hi,

What device are you using to sniff the can bus and what program, please?

Cheers,
Mike.

The device is a VN1610 used with CANalyzer software, both from a German company called Vector. I'm lucky because I work in the automotive braking sector, and have access to these tools through work.

Ah ok, That is quite a bit out of my price range.

I am trying to use the USB2CAN device from 8devices on Linux using the canbus utils package but not having any luck sniffing.
