Symptom:
INCOMPLETE LATCH RELEASE- PAWL SWITCH FAILURE
When Monitored and Set Condition:
INCOMPLETE LATCH RELEASE- PAWL SWITCH FAILURE
When Monitored: Whenever the power liftgate is operating in an opening direction.
Set Condition: The release operation was not completed in 4 seconds or the release
operation has detected a stall condition. The ratchet switch was detected as grounded but
the pawl remained open. This code is set during the power releasing operation from a fully
closed liftgate.

Symptom:
INCOMPLETE LATCH RELEASE- SECTOR GEAR RETURN FAIL-

When Monitored and Set Condition:
INCOMPLETE LATCH RELEASE- SECTOR GEAR RETURN FAILURE
When Monitored: Whenever the power liftgate is operating.
Set Condition: If the cinch release motor takes longer than 700 ms to perform a release
operation this code will set. The main causes of this code setting is some type of sticking
situation preventing the sector gear in the cinch release motor assembly to return to its
neutral position.

feature in the software and will set if the obstacle detection feature becomes inoperative
due to a hall sensor/connection malfunction.
