Question; I’m trying to control the cooling fan in the car, I have found the following CAN messages (ISO-TP frames) and am wondering if these can be used in the CAN XML, or sent via an action from RealDash.
its a request/response,
0x7E0 is the request ID
0x7E8 is the response ID
from what I can see to turn on the fan I need to send;
0x7E0: 10 08 2F 09 9B 03 00 40 <!-- the request -->
0x7E8: 30 00 00 00 00 00 00 00 <!-- the response (flow control - send data -->
0x7E0: 21 00 40 00 00 00 00 00 <- the request - remaining Bytes -->
essentially if I decode the ISO-TP message I get:
10 - single frame
08 - number of bytes ( full message = 2F 09 9B 03 00 40 00 40 )
2F - take control of the ECU input/output
09 9B - ID of the fan
03 00 40 - first bytes
30 00 00 00 00 00 00 00 - this is flow control - send all data without waiting
21 - Consecutive frameID
00 40 - remaining bytes
or has anyone else found a way to control “things” via can messages?
