Symptom:
INCOMPLETE POWER OPEN - MISSING HALL SIGNAL
When Monitored and Set Condition:
INCOMPLETE POWER OPEN - MISSING HALL SIGNAL
When Monitored: Anytime the power sliding door is in the opening cycle.
Set Condition: If the Power Sliding Door Module detects a missing hall effect signal for
longer than 300 ms. during an opening 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 effect sensor or connector malfunction.
