Check your front brake light switch! It appears to be faulty. Also check that the handguard is not touching the end of the brake lever.

Yes, at the time when the image was taken, my front brake lever was not able to return fully without me giving a nudge. Brake light therefore was activated. I have replaced it since and now it's working fine.
As for the whining sound, i figured it may not be coming from the ABS pump after all but a sticky fuel pump relay. I will do a check soon. About the rear brake if it's running on residual braking, is there any way to determine for sure, other than 'feeling' it?
As for the rear brake light, anything i should be looking for when the globe (i assume its the big chunky cover) is removed. Meanwhile, i am monitoring further with gs911 before my ride on the status.

After fixing the front brake lever, do you still have the error?

Now that you've pointed me to this. I have just observed that when i bled test with 911 on either rear or front brake, then the dashboard ABS blinking comes on and 911 would also indicate that the Active Brake Front as 'Not Running'. At times both Active Brake Front and Rear showed as 'Not Running'. Before bleeding and without errors they show as 'Running'. Pressure sensors are within specs 17 - 19 bar. Can you tell me what does the Active Brake Front/Rear refers to? the microswitch on the lever and pedal that turns on the rear brake light? I had my front lever assembly with master cylinder replaced just days back, it seemed to operate well.
Also i just opened up the rear light box (globe) and checked both filaments, they are straight and connected. Should i get another bulb just to eliminate possibility?

Yes, they persist.

The Active Brake appears to point to the fact that the ABS Functionality is active and working. I speak under correction and will check as soon as I can get my hands on an 1150.

Just make sure that the one filament works as a tail light and the other one comes on when you apply the brakes. As long as both filaments are working, all is good with the globe.
