freeway243, any good news to update? Also looking to do this as well with the comma system on my 15’ RCF

I don't think your model year offered lane departure alert so that might be an issue. I'll have to look at tech stream. As for me I miswired a CAT6 cable after I plugged in my forward recognition camera to a new wiring harness in the roof. Doing this made the forward collision camera send a can message to other subsystems saying look for me later. This disabled cruise control, pcs and BSM on my car. Then, when I miswired the cable I potentially shorted something in the CAN bus from the forward camera. So now it may be more difficult for me to resolve this. However I believe vraa got it to work on his car.

Whats weird is UK rcF had lane departure option for 15-17 and use all the same pre-collision. Currently in the middle of retrofitting a heated steering and it also has the lane depart button, so looking into the LDA schematics. I might just need to reflash the driver support ECU or combination meter/cluster to support LDA.

Also wanted to verify you were adding LKA to your already equipped LDA equipped car correct?

I'd be interested to see how reflashing goes... Here in the US I was told I was out of luck and to get firmware for the newer years I'd have to buy the newer hardware. No did not have LDA. 2020 model year steering angle sensor has an extra connector that my 17 did not. I would guess that's where you would connect for heated steering... Might be a problem

Current running theory is Gateway is filtering out traffic from Camera to brakes, cruise and EPS. Here is Can diagram

Got my RC-F to work/ be self driving. Here's a quick clip.

Very cool and nice job, how much money total do you have in it that retrofit?

Freeway243

I have many thousands in it. However, you don't need nearly as many parts as I originally thought. The only part someone would need to do this is the EPS for $550 and if you want to do less coding the lane keep assist camera helps.
