No.1 DOES NOT LATCH RELEASE WITH LIFTGATE OUTER HANDLE SWITCH [POWER LIFTGATE (PLG) SYSTEM]

id0903c9999500

1 | Does not latch release with liftgate outer handle switch
--- | ---
DESCRIPTION | • The liftgate is not released latch when using the liftgate outer handle switch.
POSSIBLE CAUSE | • Malfunction in liftgate outer handle switch related part ― Liftgate outer handle switch malfunction ― Open or short to ground circuit in wiring harness between liftgate outer handle switch and PLG control module ― PLG fuse melt or damaged • Malfunction in closer motor related part ― Closer motor malfunction ― Open circuit in wiring harness between closer motor and PLG control module • PLG control module can not recognize latch release possible condition ― Door lock state signal incorrect ― BCM malfunction • CAN communication error (Symptom appears while the ignition switch is ON position only.) ― Improper vehicle speed signal from PCM ― Improper transaxle range signal from TCM • 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 IF MALFUNCTION IS IN CAN COMMUNICATION SIGNAL OR ELSEWHERE • Is the symptom appears while the ignition switch is ON position only? | Yes | Go to Step 7.
No | Go to the next step.
2 | INSPECT LIFTGATE OUTER HANDLE SWITCH • Inspect the liftgate outer handle switch. (See LIFTGATE OUTER HANDLE SWITCH INSPECTION.) • Is the liftgate outer handle switch normal? | Yes | Go to the next step.
No | Replace the liftgate outer handle. Note • The liftgate outer handle switch is integrated with the liftgate outer handle. (See LIFTGATE OUTER HANDLE REMOVAL/INSTALLATION.)
3* | INSPECT WIRING HARNESS BETWEEN PLG CONTROL MODULE AND LIFTGATE OUTER HANDLE SWITCH • Turn the ignition switch to OFF position. • Disconnect the liftgate outer handle switch and PLG control module connectors. • Inspect for open or short to ground circuit for following: ― Between liftgate outer handle switch terminal A and PLG control module terminal 3O ― Between liftgate outer handle switch terminal B and PLG control module terminal 3R • Is open or short for ground circuit detected? | Yes | Repair or replace malfunctioning part. Replace the PLG fuse if necessary.
No | Go to the next step.
4 | 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.)
5* | 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.
6 | INSPECT POWER DOOR LOCK SYSTEM • Inspect the power door lock system operation. • Does the power door lock operate properly? | Yes | Replace the PLG control module. (See POWER LIFTGATE (PLG) CONTROL MODULE REMOVAL/INSTALLATION.)
No | Replace the BCM. (See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION.)
7 | INSPECT VEHICLE SPEED SIGNAL • Access PCM PID VSS using M-MDS. (See PID/DATA MONITOR INSPECTION [POWER LIFTGATE (PLG) SYSTEM].) • Is the PID monitoring value normal? | Yes | Go to the next step.
No | Inspect and repair for followings: • ABS wheel speed sensor • CAN communication (DSC/RSC HU/CM—PCM—PLG control module)
8 | INSPECT IF MALFUNCTION IS IN TRANSAXLE RANGE SIGNAL OR ELSEWHERE • Access TCM PID TR using M-MDS. (See PID/DATA MONITOR INSPECTION [POWER LIFTGATE (PLG) SYSTEM].) • Is the PID monitoring value normal? | Yes | Replace the PLG control module. (See POWER LIFTGATE (PLG) CONTROL MODULE REMOVAL/INSTALLATION.)
No | Inspect and repair for followings: • TR switch • CAN communication (TCM—PLG control module)
