Diagnostic Procedure

Step	Inspection		Action
1	INSPECT FRONT DOOR LATCH AND LOCK ACTUATOR (DRIVER'S SIDE) CONNECTOR CONDITION • Switch the ignition off. • Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.) • Disconnect the front door latch and lock actuator (driver's side) connector. • Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. • Is the connector normal?	Yes	Go to the next step.
1		No	Repair or replace the connector, then go to Step 6.
2	INSPECT FRONT DOOR LOCK-LINK SWITCH (DRIVER'S SIDE) GROUND CIRCUIT FOR OPEN CIRCUIT • Verify that the front door latch and lock actuator (driver's side) connector is disconnected. • Inspect for continuity between the following terminal (wiring harness-side) and body ground: ? Front door latch and lock actuator (LH) terminal J?Body ground (L.H.D.) ? Front door latch and lock actuator (RH) terminal D?Body ground (R.H.D.) • Is there continuity?	Yes	Go to the next step.
2		No	Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals: • Front door latch and lock actuator (LH) terminal J?Body ground (L.H.D.) • Front door latch and lock actuator (RH) terminal D?Body ground (R.H.D.) If there is a common connector: • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit. • Repair or replace the malfunctioning part. If there is no common connector: • Repair or replace the wiring harness which has an open circuit. Go to Step 6.
3	INSPECT FRONT DOOR LOCK-LINK SWITCH (DRIVER'S SIDE) • Inspect the front door lock-link switch (driver's side). (See FRONT DOOR LOCK-LINK SWITCH INSPECTION.) • Is the front door lock-link switch (driver's side) normal?	Yes	Go to the next step.
3		No	Replace the front door latch and lock actuator (driver's side), then go to Step 6. (See FRONT DOOR LATCH AND LOCK ACTUATOR REMOVAL/INSTALLATION.)
4	INSPECT POWER LIFTGATE (PLG) CONTROL MODULE CONNECTOR CONDITION • Disconnect the power liftgate (PLG) control module connector. • Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. • Is the connector normal?	Yes	Go to the next step.
4		No	Repair or replace the connector, then go to Step 6.
5	INSPECT FRONT DOOR LOCK-LINK SWITCH (DRIVER'S SIDE) UNLOCK CIRCUIT FOR OPEN CIRCUIT • Verify that the power liftgate (PLG) control module and front door latch and lock actuator (driver's side) connectors are disconnected. • Inspect for continuity between the following terminals (wiring harness-side): ? L.H.D.: • Front door latch and lock actuator (LH) terminal D?Power liftgate (PLG) control module terminal 1U • Front door latch and lock actuator (LH) terminal B?Power liftgate (PLG) control module terminal 1V ? R.H.D.: • Front door latch and lock actuator (RH) terminal J?Power liftgate (PLG) control module terminal 1U • Front door latch and lock actuator (RH) terminal L?Power liftgate (PLG) control module terminal 1V • Is there continuity?	Yes	Go to the next step.
5		No	Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals: • L.H.D.: ? Front door latch and lock actuator (LH) terminal D?Power liftgate (PLG) control module terminal 1U ? Front door latch and lock actuator (LH) terminal B?Power liftgate (PLG) control module terminal 1V • R.H.D.: ? Front door latch and lock actuator (RH) terminal J?Power liftgate (PLG) control module terminal 1U ? Front door latch and lock actuator (RH) terminal L?Power liftgate (PLG) control module terminal 1V If there is a common connector: • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit. • Repair or replace the malfunctioning part. If there is no common connector: • Repair or replace the wiring harness which has an open circuit. Go to the next step.
6	VERIFY THAT REPAIRS HAVE BEEN COMPLETED • Always reconnect all disconnected connectors. • Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.) • Clear the DTC for the power liftgate (PLG) control module using the M-MDS. (See CLEARING DTC [POWER LIFTGATE (PLG) CONTROL MODULE].) • Switch the ignition off and wait for 1 s or more. • Retrieve the power liftgate (PLG) control module DTCs using the M-MDS. (See DTC INSPECTION [POWER LIFTGATE (PLG) CONTROL MODULE].) • Is the same DTC displayed?	Yes	Repeat the inspection from Step 1. • If the malfunction recurs, replace the power liftgate (PLG) control module. (See POWER LIFTGATE (PLG) CONTROL MODULE REMOVAL/INSTALLATION.) Go to the next step.
6		No	Go to the next step.
7	VERIFY IF OTHER DTCs DISPLAYED • Are any other DTCs displayed?	Yes	Repair or replace the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [POWER LIFTGATE (PLG) CONTROL MODULE].)
7		No	DTC troubleshooting completed.
