2005 R1200RT iABS Input Sensors Reversed

[ride4funfix2ride]

2005 R1200RT iABS Type 0315 Series K26

Thanks in advance for your help.

Questions:

GS-911 Wifi Real Time Data  shows Front and Rear inputs reversed.  In Realtime ABS sensor read. Front and rear sensors appear to be swapped.

    Squeeze in front brake GS-911  registers as rear activation

    Press on rear brake pedal GS-911 registers as front brake activation

Is this a bug in GS-911?

Assuming not. Where are the sensor terminations?

iABS unit is newer than Bike per ABS ECU dump See Dump below

All other functional test are good

Drift, Bleed Front, Bleed Rear return successful

Is throwing low fluid code: 25193

Prior bleed via JVB methods in Feb 2019

Details below



History

Oct 2017 Purchased Private Sale: Questionable Service History based on discovery of non-standard cross threaded spark plug in 2019.

July 2018 Brake Fail Light Issue first appeared in Summer heat long trip

Brakes and servo operate fine.

Rear brake demonstrates ABS

Front Brake Hard Squeeze will produce Stoppie.. Rear wheel up

Intermittent .. then permanent

Feb 2019 performed full fluid bleed and replace followingJVB beemer boneyard procedure.

No significant change

       Brakes and servo operate fine.

Rear brake demonstrates ABS on full press

Front Brake Hard Squeeze produce Stoppie.. Rear wheel up.

 No indication of ABS engaged on front but no tire skid either

Red Indicator and Brake fail always flash 1 second

April 2020 GS-911Wifi Purchase

   1 ABS Fault code

   25193: Brake Fluid level too low

      Both Visible fluid reservoirs are full. Assume Servo reservoirs are low, sensor fail or CANbus issue?

Also Noted:  In Realtime ABS sensor read. Front and rear sensors appear to be swapped

      Squeeze in front brake GS-911  registers as rear activation

      Press on rear brake pedal GS-911 registers as front brake activation

      

Could the sensor inputs be swapped at the head? Logically this would not be good for an integral ABS? But...No issues or errors for first 5K miles in possession of Bike

'06 R1200GS and 1st Brake Bleed and I created flashing ABS on dash...  Broke it back down to do another and more official Brake Bleed and with newly purchased GS-911.  Same error message... low fluid, but all 3 Reservoirs are at their proper levels (visiualed).  These stupid smart bikes... so far I'm defeated, too. 

Dunno if this Reply will bump us up and maybe you already overcame the issue in a way that would NOT include a Dealer?  Good Query... thanks.
