My air suspension showed the dreaded E4 error. After studying Freebirds (thanks!) thread on the topic I tackled it today.
Removed the control unit from the bike (5 mins) and disassembled it while I was home for lunch.
These eyes are getting old so I really couldn't see solder breaks very well, so later in the afternoon I stopped at Radio Scrap and bought a hands free with magnifying glass, and some finer gauge solder.
Tonight after work while I still had light I thought what the heck go for it. Re-soldered 4 pins on one connector and a few on the other. Put it back together and re-installed it.
Turned the key and everything worked! Yes I was surprised and pleased with myself, and grateful to this forum for keeping me rolling.
And then since it was a very nice evening here in Salem Oregon I took it for a ride.
Thank you!
