soondin Posted April 30, 2021 Report Share Posted April 30, 2021 I just check for wiring and made chart for start engine. But looks like this car use CANBUS for AC Request. Any one have information for this things? And this car need to control Alternator? Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 30, 2021 Report Share Posted April 30, 2021 I dont know specifically for this model, but most of the Honda alternators will work ok without ECU control. Normally the ECU control is only used to switch it into low voltage mode to save fuel/emmisions when cruising at light load. Picture below taken from this document: https://www.giac.org/paper/gcia/9927/hacking-bus-basic-manipulation-modern-automobile-bus-reverse-engineering/133228 Shows some data from a 2011 civic. I have no idea if it matches your car. But if so then ID164, Byte 3 looks interesting (byte 2 in Link since byte numbering starts from 0).

Vaughan Posted May 2, 2021 Report Share Posted May 2, 2021 The DC5 Integra type R that I have played with uses KLine for the AC request from memory, not CAN Quote Link to comment Share on other sites More sharing options...
