DTC B1495:1C [POWER LIFTGATE (PLG) CONTROL MODULE]

id0902o8977600

Description	Foot-motion detection unit power supply voltage low or high input
Detection condition	• Foot-motion detection unit detects that the power supply circuit voltage that is less than the specification • Foot-motion detection unit detects that the power supply circuit voltage of specification or more
Fail-safe function	• Stops the hands-free liftgate operation.
Possible cause	• DTCs are stored in the PCM. ? Generator system malfunction • ROOM 25 A fuse malfunction • INTERIOR2 15 A fuse malfunction • Battery malfunction • Foot-motion detection unit connector malfunction • Open circuit or short to body ground in wiring harness between battery positive terminal and foot-motion detection unit terminal 1B • Open circuit in the wiring harness between the foot-motion detection unit terminal 1A and body ground • Foot-motion detection unit malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	INSPECT PCM DTC (INSPECT GENERATOR CIRCUIT) • Retrieve the PCM DTCs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.5T)].) • Are any DTCs displayed?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [PCM (SKYACTIV-G 2.5T)].)
1		No	Go to the next step.
2	INSPECT FUSE • Switch the ignition off. • Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.) • Remove the ROOM 25 A, and INTERIOR2 15 A fuses. • Are the fuses normal?	Yes	Install the ROOM 25 A, and INTERIOR2 15 A fuses, then go to the next step.
2		No	If the ROOM 25A fuse or INTERIOR2 15 A fuse is blown: • Refer to the wiring diagram and verify whether or not there is a common connector between ROOM 25 A fuse and foot-motion detection unit terminal 1B. 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. If the fuse is damaged: • Replace the fuse. Then go to Step 7.
3	INSPECT BATTERY • Inspect the battery. (See BATTERY INSPECTION.) • Is the battery normal?	Yes	Go to the next step.
3		No	Replace or charge the battery. (See BATTERY RECHARGING.) (See BATTERY REMOVAL/INSTALLATION.) Then go to Step 7.
4	VERIFY FOOT-MOTION DETECTION UNIT CONNECTOR CONDITION • Disconnect the foot-motion detection unit connector. (See FOOT-MOTION DETECTION UNIT REMOVAL/INSTALLATION.) • 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 7.
5	INSPECT FOOT-MOTION DETECTION UNIT POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT • Verify that the foot-motion detection unit connector is disconnected. • Inspect for continuity between the foot-motion detection unit terminal 1B (wiring harness-side) and battery positive terminal. • 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 foot-motion detection unit terminal 1B and battery positive terminal. 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	INSPECT FOOT-MOTION DETECTION UNIT GROUND CIRCUIT FOR OPEN CIRCUIT • Verify that the foot-motion detection unit connector is disconnected. • Inspect for continuity between the foot-motion detection unit terminal 1A (wiring harness-side) and battery positive terminal. • Is there continuity?	Yes	Go to the next step.
6		No	Refer to the wiring diagram and verify whether or not there is a common connector between foot-motion detection unit terminal 1A and body ground. 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.
7	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 2 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 foot-motion detection unit. (See FOOT-MOTION DETECTION UNIT REMOVAL/INSTALLATION.) Go to the next step.
7		No	Go to the next step.
8	VERIFY THAT NO OTHER DTCs ARE PRESENT • 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].)
8		No	DTC troubleshooting completed.
