If the piston is off center in the PDWA, the switch will be activated
and the light will glow. The condition of your brakes doesn't matter. For
example if your system was set correctly and you had a brake failure and
fixed it but didn't recenter the PDWA piston you'd still get a warning light.
Checking the PDWA switch is easy. Do a continuity check from the
switch terminal to ground. If you get a reading your switch is closed. I
think the instructions for recentering are on the VTR maintenance site. Hope
this helps
