id0903c9999700

2

Does not operate liftgate auto closure
DESCRIPTION
•  Liftgate is not pulled in from adjure position when the liftgate is closing.
POSSIBLE CAUSE
•  Malfunction in closer motor related part
―  Closer motor malfunction
―  Open circuit in wiring harness between closer motor and PLG control module
•  Malfunction in latch position switch related part
―  Half latch switch malfunction
―  Open or short to POWER/ground circuit in wiring harness between liftgate latch and lock actuator and PLG control module
•  PLG control module malfunction

When performing an asterisked (*) troubleshooting inspection, slightly shake the wiring harness and connectors while performing the inspection to discover whether poor contact points are the cause of any intermittent malfunctions. If there is a problem, verify that the connectors, terminals and wiring harnesses are connected correctly and undamaged.

Diagnostic procedure

Repair or replace malfunctioning part.
No
Go to the next step.
3
INSPECT HALF LATCH SWITCH
•  Inspect the half latch switch.
•  Is the half latch switch normal?
Yes
Go to the next step.
No
Replace the liftgate latch and lock actuator.
(See LIFTGATE LATCH AND LOCK ACTUATOR REMOVAL/INSTALLATION.)
4*
INSPECT WIRING HARNESS BETWEEN PLG CONTROL MODULE AND HALF LATCH SWITCH
•  Turn the ignition switch to OFF position.
•  Disconnect the liftgate latch and lock actuator and PLG control module connectors.
•  Inspect for open or short to POWER/ground circuit between liftgate latch and lock actuator terminal B and PLG control module terminal 3H.
