E93 seatback monitoring failed
Hi! I'm building an E90 simrig. At this time I only have the KOMBI(instrument cluster) and I've managed to control it using an Arduino UNO and SEEED's Can Bus Shield. The only thing left are the SOS error and the seatback error. and the check engine, which probably lights up because of the errors
Do they have to get coded out or can I emulate them on the K-CAN bus? Any help will be appreciated. |

After digging a bit I found that the driver's seat(left) sends 0xF0, 0xFF, 0x35, 0xFF to id 0x34B when idle, however the first bit changes(maybe increments) from 0xF0 to 0xFE. In other places it is written that 0x34B is 8 bytes long, so I will also try sending 0xF0, 0xFF, 0x35, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF with the first byte incrementing.
