Please help with the electronic handbrake

[depo1902]

Hello dear owners of French cars!
When trying to free the rear calipers using diagbox 9.68 to replace the rear pads, several bugs popped up, including the C156D62 which does not wear off and the handbrake is no longer tightened.
In this case, the handbrake signs are constantly flashing on the dashboard.
Today I checked the wiring, it is intact without damage.
My car is a 2018 Citroen c4 Grand picasso, 1.6 bluehdi engine with aisin automatic transmission.
Unfortunately, I do not know English and I use google translator, thanks for your understanding.

Might be worth trying to recalibrate the system with diagbox & go through the procedure as if you have replaced the calipers/cables.

Good night, my friend. I have a great friend who has changed the rear pads of a Citroen C4 Grand Picasso 2018. And you have the same fault as you, the C157D. Could you tell me if I solve it, and how did you get it? A cordial greeting from Spain.
