DTC U3006:13 [POWER LIFTGATE (PLG) CONTROL MODULE]

id0902o8049800

Description	Power supply circuit malfunction
Detection condition	• Power liftgate (PLG) control module detects an open circuit in the power supply circuit for 1 s or more with the ignition switched off.
Fail-safe	• Stops the power liftgate (PLG) system operation.
Possible cause	• DTCs are stored in the PCM. • Battery malfunction • Generator malfunction • Power liftgate (PLG) control module connector or terminal malfunction • Power liftgate (PLG) control module power supply circuit malfunction ? Short to ground in wiring harness between MAIN 200 A fuse and power liftgate (PLG) control module terminal 2I ? PLG 20 A fuse malfunction ? CABIN.+B 50 A fuse malfunction ? Open circuit in wiring harness between battery positive terminal and power liftgate (PLG) control module terminal 2I • Power liftgate (PLG) control module malfunction

Diagnostic Procedure

STEP	INSPECTION		ACTION
1	VERIFY PCM DTCs • Retrieve the PCM DTCs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.5T)].) • Are any DTCs displayed?	Yes	Repair or replace the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [PCM (SKYACTIV-G 2.5T)].)
1		No	Go to the next step.
2	INSPECT BATTERY • Inspect the battery. (See BATTERY INSPECTION.) • Is the battery normal?	Yes	Go to the next step.
2		No	Recharge or replace the battery, then go to Step 6. (See BATTERY RECHARGING.) (See BATTERY REMOVAL/INSTALLATION.)
3	INSPECT GENERATOR • Inspect the generator. (See GENERATOR INSPECTION [WITHOUT i-ELOOP (SKYACTIV-G 2.5T)].) (See GENERATOR INSPECTION [WITH i-ELOOP (SKYACTIV-G 2.5T)].) • Is the generator normal?	Yes	Go to the next step.
3		No	Replace the generator, then go to Step 6. (See GENERATOR REMOVAL/INSTALLATION [WITHOUT i-ELOOP (SKYACTIV-G 2.5T)].) (See GENERATOR REMOVAL/INSTALLATION [WITH i-ELOOP (SKYACTIV-G 2.5T)].)
4	INSPECT POWER LIFTGATE (PLG) CONTROL MODULE CONNECTOR CONDITION • Switch the ignition off. • Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.) • 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	VERIFY POWER LIFTGATE (PLG) CONTROL MODULE POWER SUPPLY VOLTAGE • Always reconnect all disconnected connectors. • Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.) • Measure the voltage at the power liftgate (PLG) control module terminal 2I (wiring harness-side). • Is the voltage B+?	Yes	Go to the next step.
5		No	Inspect the PLG 20 A fuse and CABIN.+B 50 A fuse. • Any fuse is blown: ? Refer to the wiring diagram and verify whether or not there is a common connector between MAIN 200 A fuse and power liftgate (PLG) control module terminal 2I. 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. • Replace the fuse. • Any fuse is damaged: ? Replace the fuse. • All fuses are normal: ? Refer to the wiring diagram and verify whether or not there is a common connector between battery positive terminal and power liftgate (PLG) control module terminal 2I. 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.
