Thank you for these instructions! I am troubleshooting a error 18 (fan). I replaced the fan assembly but no success during the fan test. So i check the electrical resisitance between pins 3 and 4 (voltage input) of the fan conector, and it has a value around 3 Mohm. Do you know what should be this value? Thanks
I troubleshoot more and realized that the 16V input voltage is always "on" in the fan connector, and during the BIT test step, the fan only works when I unplug and plug back the input voltage pins (red and black). Have you seen it before? Than you
ok so done the BIT mode on my S7. I never knew that existed, thanks for that. What is NOT working is bumper L& R, Drop L&R, all cliff sensors, IR comms. The vac I purchased from an auction with a "charging fault" clearly not that. Do you think its worth getting a replacement motherboard, or stripping down first to check all the connections. I can see boards on a well know chinese website. thanks

Great video, thanks very much
i just learn how this machines works, thanks :)
excellent many thanks putting this on line, will do on my faulty s7 later.
How to run Test Mode if my Back to Station button is broken. Is there any other method from the app, via Putty or some other method?
