Re: E38 HS canbus messages
1A1 looks promising.. I think it's more A/c clutch applied/A/c clutch not applied, not the request your looking for.. I can confirm the 1A1 messages are the status for the "A/C Clutch Engaged" (on or off) 1A1 - 00 2 00000 = status on 1A1 - 00 3 00000 = status on (when on via scan tool) 1A...

Re: E38 HS canbus messages
I didn't think/know you were using the BCM.. This might throw a wrench in the works for the a/c request but I'm not sure.. I have the BCM but not sure if I want to run it as I cant seem to get the things I want from it: I was hoping to get reverse lights, ac request, tutd, cruise and variable charg...

Re: E38 HS canbus messages
What else do you have available besides hptuners? Do you have a gm MDI? can you monitor a/c request with hptuners? that should change from no to yes when sending that command, that is what I am seeing with tech2win.. hptuners has the following channels that can be monitored. -AC Clutch Engaged -AC ...

Re: E38 HS canbus messages
I initially thought you were referencing the device control messages (the 0xAE in the 1F1 messages through me off track): -7E0 07AE203000000000 AC clutch on -7E0 07AE200000000000 AC clutch (standard) -7E0 07AE202000000000 AC clutch off I suspect the 1F1 addressed messages you suggest are the ones I ...

Targeting the 2011 E38 for the L77 6.0 - OS 12639270 1F1AE1600000800007A << this turns the ac clutch on in the subur...

E38 HS canbus messages
Does anyone have any canbus data they can share? Especially keen for VE commodore? I am currently doing an L77 VE Holden Commodore engine conversion (without BCM) into a holden rodeo and I am trying to learn what all the messages are. The GMLAN bible doesn't really cover the 11 bit HS can much so I ...
