ABS Mk60: Zero-Code Functionality?

A hello from the newbie in this super knowledgeable forum!

My questions about the onboarding process:


Is the Mk60 functional in its default state (zero encoding)?

Is the ABS light just indicating the need for a coding procedure, or does it also indicate a system failure?

Can the Mk60 (1K0614517AC) be programmed while it's displaying an error code?

Background:
I cannot clear the ESP errors because the ESP sensors are missing.
I'm only interested in the ABS function!


Sure, here's the translation:
