Adjusting DI rear derailleur on Shimano STEPS bike

[Deleted member 4366]

I've been trying to adjust one of these today with no luck. In the normal STEPS LCD menu is "adjust", which takes you to a setting where you can adjust the derailleur in steps of 1/16 of a complete shift step. I can adjust up and down, but every time I try the bike, it sets it back to how it was. It needs shifting about 2 x 1/16 step AFAICS by eyeballing it. Does anybody know how to save this setting or how it works?

You`ve probably done this, but no mention of `Store` or similar? must be in the Menu somewhere..

Step 1: Shift the rear derailleur up to the 4th or 5th cog.


Step 2: Hold the button down on the control box until the red light turns on.


Step 3: You will then be able to use the shifting buttons to make minor adjustments to the alignment of the rear derailleur in the direction the shift would normally go.


Step 4: Align the rear derailleur pulley directly under the appropriate cog and then hold the button on the control box until the red light turns off. Shift through the gears to check the index.


Step 5: Shift your rear derailleur into the largest cog and adjust the low limit by rotating the screw on your derailleur marked ÒLÓ so that it lines up with that largest cog.


Step 6. Shift your rear derailleur into the smallest cog and adjust the high limit by rotating the screw on your derailleur marked ÒHÓ so that it lines up with that smallest cog.

That's the normal Di2. This one is the STEPs version that has no control box. Instead, it's integrated into the ebike's display. I found an instruction for it, but it's not very clear. It tells me everything I did except how to save the setting.
It's here on page 5.22

i've no idea what it means when it says, "adjust by rotating the crank". After adjusting the setting with the buttons, the crank symbol appears on the display. I tried rotating the crank until the symbol disappeared, but that doesn't save it.

i cant see any way to save the data either or it needs to be plugged in to a laptop to save settings like that?

How strange.
A Tech Tip on page 5.21 says... Gear shifting adjustment can only be performed when an electronic gear shifting unit is connected.
Inferring that it does need to be connected???

That's in there because it's an instruction for the display. The "adjust" function is in all displays, but obviously it doesn't do anything if you don't have Di2 shifting. If you have Di2 shifting, it's connected all the time.

Di2 shifting is controlled differently on unpowered bikes and electric bikes. The derailleurs with their servos are the same, but for unpowered bikes, they're connected to a control box with batteries in it and the controlling electronics and software. On electric bikes with the Shimano motor system, it connects directly in to the system, using the STEPS software and the ebike's battery.
