2013 Porsche Boxster EPB

The EPB can be tested with RBT
The EPB will automatically put itself in test mode as soon as one axle is driven while the other is stationary .
Indications of this is a message displayed on instrument panel stating "parking brake service mode"

To test the parking brake the button needs to be pressed "continuously "until the max efforts are acheived
The service brake can be tested as normal

The EPB will reset itself once both axles are driven at the same speed
