No.2 DOES NOT OPERATE LIFTGATE AUTO CLOSURE [POWER LIFTGATE (PLG) SYSTEM]

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

STEP | INSPECTION | ACTION
--- | --- | ---
1 | INSPECT CLOSER MOTOR • Inspect the closer motor. (See LIFTGATE LATCH AND LOCK ACTUATOR INSPECTION.) • Is the liftgate latch and lock actuator normal? | Yes | Go to the next step.
No | Replace the closer motor. (See LIFTGATE LATCH AND LOCK ACTUATOR REMOVAL/INSTALLATION.)
2* | INSPECT WIRING HARNESS BETWEEN PLG CONTROL MODULE AND CLOSER MOTOR • Turn the ignition switch to OFF position. • Disconnect the closer motor and PLG control module connectors. • Inspect for open or short to ground circuit for following: ― Between closer motor terminal A and PLG control module terminal 1A ― Between closer motor terminal B and PLG control module terminal 1B • Is open circuit detected? | Yes | Repair or replace malfunctioning part.
No | Go to the next step.
3 | INSPECT HALF LATCH SWITCH • Inspect the half latch switch. (See LIFTGATE LATCH AND LOCK ACTUATOR INSPECTION.) • 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. • Is open or short circuit detected? | Yes | Repair or replace malfunctioning part.
No | Replace the PLG control module. (See POWER LIFTGATE (PLG) CONTROL MODULE REMOVAL/INSTALLATION.)
