Hello,
I purchased GS911 enthusiast version few years ago and I am very pleased
with its performance and possibility.
Right now I am diagnosing K1200LT year 2000 with ABS generation 2. I am
receiving error code numer 16 with text explanation of "ABS PISTON FAILED"
while sometimes error code 16 has explanation "PLUNGER TEST FAILED".
I know that BMW ABS2 performs plunger test at pull away after startup with
well known "kerklank" sound from modulator, where it checks if the plungers were
moved by engaging traction clutch.
Modulator monitors just plunger movement ( one coil for front and one coil
for rear plunger) and does not monitor brake pistons if they were moved and
does not monitor brake pressure.
I found error codes for ABS2 modulators on web page
http://www.largiader.com/abs/absfault.htmlbut I am not sure how ABS PISTON FAILED error code #16 is generated if
PLUNGER TEST passed.
Any help or suggestion would be appreciated.
Silvo
