I understand the procedure after prolonged disconnect is as follows:

Ignition on, engine not running.

Open throttle fully. Hold 1 second. Return to closed.

Repeat 2 more times for total of 3.

Turn bike off.






Morning Fugu

That should work but no need to hold open for 1 second.

All It needs is key-to-on (not running), then fully open then fully close throttle once (that is basically it).

Most do the "fully open then fully close throttle" 3 times but the second & third times are not really needed on the hexhead (but it doesn't hurt either).

I didn't see this in the thread.

Is the ESA shocks connected on the bike? You say it doesn't work. I wonder if the non-working ESA shocks are stopping the ZFE from allowing power to the windscreen.

On my 2006, the ESA is disconnected. I get the error on my GS-911 all the time, that the ESA does not have correct voltage. I do not get a windscreen error code.

I had a short on the neck of the steering column. From turning the handlebars (98k miles at the time) back and forth, the harness, the wire and the black frame paint wore through and shorted out the EGR circuit, O2 sensor heating element and the idle circuits.

Hence, I am leaning towards a power circuit that powers the ESA and the windshield.

Good luck.

Thanks Nic and continued thanks to Dirtrider

I am in the middle of a bathroom remodel right above my home office. Time during the week is a bit rare right now and I’ve done nothing on the bike this work week.

That said- if I get a chance this weekend or next time I have time i intend to:

Unplug battery.
Pull Tupperware on R side and front.
Disconnect ESA front and rear all plugs. (One by lock for cubby hole in fairing, two right side rear under seat)
inspect what I can see of wiring for the windshield. Again.

By this stage I ought to have had it unplugged long enough to have reset the ZFE

Connect battery, turn on ignition
Twist throttle wide open to calibrate
Turn off ignition

Turn on ignition, connect Gs-911 and scan for then clear any codes.

Try windshield calibration.

Either celebrate, or hang myself.

Ok after they cut me down, if needed:

Swap old windscreen motor back in and try again.

Pull tank off.
Check each wire from windscreen motor plug to plug to ZFE with multi meter

Either repair or jumper around any bad wire(s)

At that point if it’s not fixed I’ll drink myself silly.

Well I haven’t hung myself yet.

The ESA shocks are in the trash bin. All plugs unplugged.

I had the battery disconnected for a long time. Powered back up and same issues.

I had the windshield motor apart. It’s pretty simple. A small board with a hall sensor. All connections are good to plug. I have two motor assemblies here too so unless they have identical failures it’s gotta be the bike one would think.

At the bike side I see ground, 5v on the terminal so labeled on the motor board, and 12v on the terminal marked HS on motor board. Assume is hall sensor.

The motor spins well when I apply 12v

Did I mention the Gs-911 reads switch contact from the handlebar switch? It does. Up and down.

Have tank off. Now trying to find wires at ZFE end. Connections in Plugs at ZFE look good/ clean shiny

I might have found a broken wire. I’m tired of screwing with this. Did shock replacement then returned to messing with windscreen.

Gray wire w/ White stripe doesn’t appear continuous between actuator plug and ZFE plug.

I need to check again when I have clear eyes. Need to check other ZFE plug as well. Don’t know which is which. I opened one, found gray w/green stripe right by gray w/ white stripe. I assume they are the ones but lots of wires. Will try to find the other three in the bundle and check the other bundle before doing anything drastic like jumping a new wire from plug to plug.

I’d be happy if it’s that one stupid wire though.

Back at it in the morning. Dinner, beverages and feet up are calling me. Been a long ass week

Morning Fugu

The Gray/White wire turns to Gray/Blue at the 5 pin connector coming from the motor, the Gray/Green stays Gray/Green all the way to the ZFE.

Thanks Dirtrider, I’m pretty sure i don’t have a gray w/blue at the actuator end unless it’s such a light blue it’s appearing white. I’ll double check shortly. Will look for gray w/ blue at the ZFE plug end as well.

Afternoon Fugu

The wire should be Gray/White at the ZFE end & change to Gray/Blue at motor plug.

Dirtrider it is definitely not gray/ blue at windscreen actuator. It’s gray w/ white.

Of the 5 wires at the actuator I can trace 4 of them from actuator plug to ZFE plug. With both ends unplugged metering from the plug pins I have continuity end to end.

The grey w/white from the actuator I just located in the other bundle to ZFE so that wire connects to ZFE just in the other bundle. Again tested with plugs pulled so theoretically just wires.

If all the wires get to ZFE I’m running out of options here. Either the original motor went bad AND the used replacement the was reportedly working went bad in the same way, or the ZFE itself is bad.

Note both motors turn when given voltage. No idea how I’d test the just bigger than a pinhead Hall effect sensor in them.

Pretty goddamn sick of this.

The gray/ white does not get there. It’s not shorted to any others that I can tell. It’s not connected to any other ZFE pins.

The killer is I jumpered it and nothing changed.

So I’m flummoxed.




Afternoon Fugu

OK, my wire schematic shows the 2005 1200RT being Gray/White as it exits the ZFE & changing to Gray/Blue at the motor HES connector (possibly BMW changed that to all Gray/White as the production year progressed.

The Gray/White wire enters in a different place at the ZFE (pin 32).

Do NOT run 12v to that Gray/white wire as it is the actuator HES sensor wire so would never see 12v.
