The multi-circuit protection valve section of the APU has been incorrectly piped. The driver could release the park brake without sufficient pressure in the service brake circuits for them to function. In this condition, the red low pressure warning light for service brake circuits will either be independently illuminated or both together, plus the low air pressure buzzer will be sounding. Recall vehicles likely to be affected to change the position of two air pipes on the APU.
