Just a quick note on the operation of the ESC system when diagnosing a fault not mentioned in the manual. I spent a couple of weeks worming (or rather whaling these days) under the van trying to track down what happened (permanent red light). I eventually phoned Alko and apparently after 10 failed attempts the module enters permanent fault mode and needs to be returned to ALKO for reset. This omission from the manual probably cost me 10 hours of 'whaling' and had me doubting my already limited electrical diagnosis skills.
I have my ESC wired into the 7 pin so every time I unplugged and plugged it in (eventually I found a failed brake magnet) the esc counted that as a failed attempt. So this is another good reason to run a dedicated Anderson plug for the esc system. Otherwise get under the van and unplug the connector to the module located just behind the vans rear axel (centre) prior to diagnosing the underlying (brake magnet/wiring) fault.
Other than 4 screws the module is attached to the van (on my Jayco anyway) with what appears to be Sikaflex 11fc and is a bugger to get off.... can't get right around it with a renovator w/ the plain (no teeth) blade.
This is the diagnosis protocol I used to find the underlying (brake) fault which is the best I came across

This is the Alko esc component
