Symptom:
INCOMPLETE POWER CLOSE - MISSING HALL SIGNAL
When Monitored and Set Condition:
INCOMPLETE POWER CLOSE - MISSING HALL SIGNAL
When Monitored: Anytime the power liftgate is in the closing cycle.
Set Condition: If the Power Liftgate Module detects a missing hall effect signal for longer
than 300 ms. during a closing operation, this code will set. This is a redundant safety
feature in the software and will set if the obstacle detection feature becomes inoperative
due to a hall sensor/connection malfunction.
