I used CAN Hacker to read the outside air temperature from the CAN bus Renault Megane II Phase 2 (2006+).
In CAN message 0x60D, the 5th data byte contains a value ranging from 0x00 to 0x63 (hex).
0x00 = −40°C
0x01 = −39°C
…
0x0A = −30°C
0x0B = −29°C
…
0x10 = −24°C
…
0x4A = 34°C
0x50 = 40°C
The maximum value displayed on the instrument cluster is:
0x63 = 59°C
Please add this data to your Hiworld LNF1.10 H1N4LNF10A CAN adapter firmware, and upload the resulting firmware .iap file here.
