Yes
Go to the next step.
No
Repair or replace the connector, then go to Step 10.
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.
No
Repair or replace the connector, then go to Step 10.
5
INSPECT FOOT-MOTION DETECTION UNIT CIRCUIT FOR SHORT TO GROUND
•  Verify that the foot-motion detection unit and power liftgate (PLG) control module connectors are disconnected.
•  Inspect for continuity between foot-motion detection unit terminal 1C (wiring harness-side) and body ground.
•  Is there continuity?
Yes
Refer to the wiring diagram and verify whether or not there is a common connector between foot-motion detection unit terminal 1C and power liftgate (PLG) control module terminal 1C.
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 a short to ground.
•  Repair or replace the malfunctioning part.
If there is no common connector:
•  Repair or replace the wiring harness which has a short to ground.
Go to Step 10.
No
Go to the next step.
6
INSPECT FOOT-MOTION DETECTION UNIT CIRCUIT FOR SHORT TO POWER SUPPLY
•  Verify that the foot-motion detection unit and power liftgate (PLG) control module connectors are disconnected.
•  Connect the negative battery terminal.
•  Switch the ignition ON (engine off or on).
•  Measure the voltage at the following foot-motion detection unit terminal 1C (wiring harness-side).
•  Is the voltage 0 V?
Yes
Go to next step.
No
Refer to the wiring diagram and verify whether or not there is a common connector between foot-motion detection unit terminal 1C and power liftgate (PLG) control module terminal 1C.
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 a short to power supply.
•  Repair or replace the malfunctioning part.
If there is no common connector:
•  Repair or replace the wiring harness which has a short to power supply.
Go to Step 10.
7
INSPECT FOOT-MOTION DETECTION UNIT CIRCUIT FOR OPEN CIRCUIT
•  Switch the ignition off.
•  Disconnect the negative battery terminal.
•  Verify that the foot-motion detection unit and power liftgate (PLG) control module connectors are disconnected.
•  Inspect for continuity between the following foot-motion detection unit terminal 1C (wiring harness-side) and power liftgate (PLG) control module terminal 1C (wiring harness-side).
•  Is there continuity?
Yes
Go to the next step.
No
Refer to the wiring diagram and verify whether or not there is a common connector between foot-motion detection unit terminal 1C and power liftgate (PLG) control module terminal 1C.
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 10.
8
RESET INSTRUMENT CLUSTER CONFIGURATION DATA
