id0902o8977900

Description	LIN communication error
Detection condition	• LIN bus communication line malfunction detected
Fail-safe	• Stops the hands-free liftgate operation.
Possible cause	• Foot-motion detection unit removed without turning off hands-free liftgate personalization settings • Malfunction in LIN bus communication line ? Power liftgate (PLG) control module terminal 1C—Foot-motion detection unit terminal 1C • Foot-motion detection unit malfunction • Power liftgate (PLG) control module malfunction

Diagnostic Procedure

Step	Inspection		Action
1	VERIFY THAT FOOT-MOTION DETECTION UNIT HAS NOT BEEN REMOVED • Verify the foot-motion detection unit installation condition. (See FOOT-MOTION DETECTION UNIT REMOVAL/INSTALLATION.) • Is the installation condition normal?	Yes	Go to Step 3.
1		No	If there is an accessory installed near the foot-motion detection unit installation area: • Go to Step 2. If there is no accessory installed near the foot-motion detection unit installation area: • After installing the foot-motion detection unit correctly, go to Step 5. (See FOOT-MOTION DETECTION UNIT REMOVAL/INSTALLATION.)
2	VERIFY HANDS-FREE LIFTGATE SETTING • Verify the hands-free liftgate function settings on the center display screen. (See CENTER DISPLAY PERSONALIZATION FEATURES SETTING PROCEDURE.) • Is the hands-free liftgate function off?	Yes	Go to the next step.
2		No	Turn the hands-free liftgate function off, then go to Step 5.
3	VERIFY POWER LIFTGATE (PLG) CONTROL MODULE DTCs AGAIN • Clear the DTC for the foot-motion detection unit using the M-MDS. (See CLEARING DTC [POWER LIFTGATE (PLG) CONTROL MODULE].) • Switch the ignition ON (engine off or on) and wait for 1 s or more. • Retrieve the foot-motion detection unit DTCs using the M-MDS. (See DTC INSPECTION [POWER LIFTGATE (PLG) CONTROL MODULE].) • Is the same DTC displayed?	Yes	Inspect the LIN comunication line. If there is any malfunction: • Refer to the wiring diagram and verify whether or not there is a common connector between power liftgate (PLG) control module terminal 1C and foot-motion detection unit 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 malfunction. ? Repair or replace the malfunctioning part. If there is no common connector: ? Repair or replace the wiring harness. • Go to Step 5. If there is no malfunction: • Go to the next step.
3		No	Go to Step 6.
4	INSPECT FOOT-MOTION DETECTION UNIT FOR MALFUNCTION DEPENDING ON REPEATABILITY • Clear the DTC for the foot-motion detection unit using the M-MDS. (See CLEARING DTC [POWER LIFTGATE (PLG) CONTROL MODULE].) • Switch the ignition ON (engine off or on) and wait for 1 s or more. • Retrieve the foot-motion detection unit DTCs using the M-MDS. (See DTC INSPECTION [POWER LIFTGATE (PLG) CONTROL MODULE].) • 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.)
4		No	Go to Step 6.
5	VERIFY THAT REPAIRS HAVE BEEN COMPLETED • Clear the DTC for the foot-motion detection unit using the M-MDS. (See CLEARING DTC [POWER LIFTGATE (PLG) CONTROL MODULE].) • Switch the ignition ON (engine off or on) and wait for 1 s or more. • Retrieve the foot-motion detection unit 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.
5		No	Go to the next step.
6	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].)
6		No	DTC troubleshooting completed.
