PDE Data Not Recording.
Diagnosis & fix steps
LOGIC: Data link to the foot sensor node is lost.
ACTION: Inspect the UltraLock connector at the first articulation point (leader hinge). Moisture here kills the signal to the lower sensors.
Red Seal field insights
RED SEAL FIX: Use an IR temp gun on the sensor. If the sensor is significantly hotter than the ambient metal, it has an internal short. Replace immediately to prevent blowing the I/O card.
