Diagnostic Procedure

Step

Inspection

Action
1
VERIFY IF OTHER DTCs DISPLAYED FOR POWER LIFTGATE (PLG) CONTROL MODULE
•  Clear the DTC for the power liftgate (PLG) control module using the M-MDS.
•  Retrieve the power liftgate (PLG) control module DTCs using the M-MDS.
•  Is DTC U3000:49 displayed?
Yes
Replace the power liftgate (PLG) control module, then go to step 7.
(See POWER LIFTGATE (PLG) CONTROL MODULE REMOVAL/INSTALLATION.)
No
Go to the next step.
2
VERIFY INSTRUMENT CLUSTER DTCs
•  Retrieve the instrument cluster DTCs using the M-MDS.
•  Is the DTC displayed?
Yes
Repair the malfunctioning part according to the applicable DTC troubleshooting.
(See DTC TABLE [INSTRUMENT CLUSTER].)
No
Go to the next step.
3
INSPECT FOOT-MOTION DETECTION UNIT CIRCUIT FOR SHORT TO GROUND
•  Switch the ignition off.
•  Disconnect the negative battery terminal.
•  Disconnect the foot-motion detection unit and power liftgate (PLG) control module connectors.
•  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 7.
No
Go to the next step.
4
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 7.
5
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 7.
6
RESET INSTRUMENT CLUSTER CONFIGURATION DATA
•  Using the M-MDS, perform the instrument cluster configuration with the As-Built data.
•  Clear the power liftgate (PLG) control module DTCs using the M-MDS.
•  Switch the ignition ON (engine off or on) and wait for 30 s or more.
•  Retrieve the power liftgate (PLG) control module DTCs using the M-MDS.
•  Is the same DTC displayed?
Yes
Using the M-MDS, perform the instrument cluster configuration (using As-Built data) again, then go to the next step.
(See INSTRUMENT CLUSTER CONFIGURATION (USING AS-BUILT DATA).)
No
Go to Step 9.
7
VERIFY IF MALFUNCTIONING LOCATION IS FOOT-MOTION DETECTION UNIT DEPENDING ON REPEATABILITY
•  Always reconnect all disconnected connectors.
•  Connect the negative battery terminal.
•  Clear the DTC for the power liftgate (PLG) control module using the M-MDS.
•  Switch the ignition ON (engine off or on) and wait for 30 s or more.
•  Retrieve the power liftgate (PLG) control module DTCs using the M-MDS.
•  Is the same DTC displayed?
Yes
Replace the foot-motion detection unit, then go to the next step.
(See FOOT-MOTION DETECTION UNIT REMOVAL/INSTALLATION.)
No
Go to Step 9.
8
