I don't believe the 7310 gives you access to that module. But the full functionality is here.

However, in terms of calibration of steps, I think its a bit of a red herring. Have a read of this topic. 2017 4.4 SDV8 Autobiography in black

I don’t believe mine is necessarily a calibration issue with my L405 steps. My working theory is that the car doesn’t know the module exists. Even though it’s on the IMC. When I plugged in the new DSCM I bought off of eBay (it’s used), both steps deployed out the second I gave it power. I’m guessing that when the module was removed, the steps from the donor car were in roof access mode. So when I plugged it in, that’s the signal that was sent to power out both steps which it did. However, going to the screen, same behavior, pressing power does nothing on the screen. There is another thread going that I replied to where the dealer inadvertently updated the car and removed the RBM module. My guess is this is the issue. I’m tempted to take the Chinese aftermarket controller and wiring harness, which allows me to have deployable side steps without having it programmed in Pivi, from my L460 and plug it into my L405 and see if I can get these working just as a test. But I’m scared that the wiring may be different and I don’t want to fry anything on my L405.

Does anyone know if the obd can bus door switches is the same on the l405 as the l460? 2023 L460 Range Rover SE P400
