2001 CHRYSLER VOYAGER ignition

Symptom:
INCOMPLETE LATCH RELEASE- SECTOR GEAR RETURN FAIL-
URE
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.

wiring and connectors for an intermittent condition. Operate the
door several times and check for any binding or other obstruc-
tions.
Perform BODY VERIFICATION TEST - VER 1.
2 Examine the liftgate for proper fit and alignment, loose/hard or torn seals, struts or
anything that would cause an obstruction to proper operation.
Manually operate the liftgate of a known good vehicle and notice the effort needed to
open and close.
Compare the effort needed on the disabled liftgate.
Especially notice the effort needed to unlatch and close the liftgate.
Does it take more effort to operate the liftgate than it should?All

Symptom:
INCOMPLETE POWER CLOSE - FULL OPEN SWITCH FAILURE
When Monitored and Set Condition:
INCOMPLETE POWER CLOSE - FULL OPEN SWITCH FAILURE
When Monitored: Whenever the power liftgate is closing.
Set Condition: The Full Open Switch was detected as closed before 200 hall effect pulses
were counted since the start of the close operation. May be triggered by an intermittent full
open switch failure, or non gear engagement

POWER DOORS - LIFTGATE

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.
