DTC    B2216    Back Door Closer does not Function Normally

for Preparation Click here


DESCRIPTION

The luggage compartment door closer consists of: 1) the luggage compartment door closer motor, which performs opener and closer operations based on signals from the cowl side junction block ECU LH; 2) 2 position detection switches (LOPN, LCLS), which check the position of the closer motor; and 3) the luggage door courtesy switch (LCTY), which sends signals to start/stop the closer operation and illuminates the luggage room light. The door unlock switch (BDCY), which is built into the luggage compartment door striker, detects whether the luggage compartment door is open or closed, and transmits ON/OFF signals to the cowl side junction block ECU LH.

HINT:
"Back door" refers to luggage compartment door.

INSPECTION PROCEDURE

1.READ VALUE OF INTELLIGENT TESTER (LUGGAGE COMPARTMENT DOOR CLOSER SWITCH)

  1. Check the Data List for proper functioning of the luggage compartment door closer switch.

    Cowl side junction block ECU LH:

    Item
    		Measurement Item / Display (range)
    		Normal Condition
    		Diagnostic Note
    OPEN POSITION SW
    		Luggage door open position switch signal / ON or OFF
    		ON: Door is closed
    OFF: Door is open
    		-
    CLOSE POSITION SW
    		Luggage door close position switch signal / ON or OFF
    		ON: Door is open
    OFF: Door is closed
    		-

    OK:
    "ON" (luggage compartment door is open/closed) appears on the screen



OK
REPLACE COWL SIDE JUNCTION BLOCK LH (COWL SIDE JUNCTION BLOCK ECU LH)
NG


2.INSPECT FUSE (TRK OPN, MPX-B, D/C CUT)

  1. Remove the TRK OPN fuse from the cowl side junction block ECU LH.

  1. Remove the MPX-B and D/C CUT fuses from the engine room No. 1 relay block.

  1. Measure the resistance of the fuses.

    Standard resistance:
    Below 1 Ω



NG
REPLACE FUSE
OK


3.CHECK WIRE HARNESS (COWL SIDE JUNCTION BLOCK LH - BATTERY AND BODY GROUND)

B107445E02

  1. Disconnect the PM, PL, PA and PD junction block connectors.

  1. Measure the voltage and resistance of the wire harness side connectors.

    Standard voltage:
    Tester Connection
    		Specified Condition
    PM-1 (FUEL) - Body ground
    		10 to 14 V
    PL-1 (MPX-B) - Body ground
    		10 to 14 V

    Standard resistance:
    Tester Connection
    		Specified Condition
    PA-14 (GND) - Body ground
    		Below 1 Ω
    PD-8 (SGND) - Body ground
    		Below 1 Ω



NG
REPAIR OR REPLACE HARNESS AND CONNECTOR
OK


4.CHECK WIRE HARNESS (LUGGAGE COMPARTMENT DOOR CLOSER ASSEMBLY - COWL SIDE JUNCTION BLOCK ECU LH AND BODY GROUND)
B107435E05

  1. Disconnect the a5 closer connector.

  1. Disconnect the W3 ECU connector.

  1. Measure the resistance of the wire harness side connectors.

    Standard resistance:
    Tester Connection
    		Specified Condition
    a5-1 (OPN) - W3-5 (LOPN)
    		Below 1 Ω
    a5-5 (CLS) - W3-6 (LCLS)
    		Below 1 Ω
    a5-3 (E) - Body ground
    		Below 1 Ω
    a5-2 - W3-1 (LCM+)
    		Below 1 Ω
    a5-6 - W3-4 (LCM-)
    		Below 1 Ω



NG
REPAIR OR REPLACE HARNESS AND CONNECTOR
OK


5.INSPECT LUGGAGE COMPARTMENT DOOR CLOSER ASSEMBLY (LUGGAGE COMPARTMENT DOOR CLOSER MOTOR)
B107434E02

  1. Remove the luggage compartment door closer.

  1. Apply battery voltage to the closer motor and check operation of the motor.

    OK:
    Measurement Condition
    		Specified Condition
    Battery positive (+) → Terminal 2
    Battery negative (-) → Terminal 6
    		Motor shaft rotates clockwise
    Battery negative (-) → Terminal 6
    Battery positive (+) → Terminal 2
    		Motor shaft rotates counterclockwise



NG
REPLACE LUGGAGE COMPARTMENT DOOR CLOSER ASSEMBLY
OK


6.INSPECT LUGGAGE COMPARTMENT DOOR CLOSER ASSEMBLY (LUGGAGE COMPARTMENT DOOR CLOSER SWITCH)

B107440E03

  1. Remove the luggage compartment door closer.

  1. Measure the resistance of the switch terminals when the switch is operated.

    Standard resistance (Open switch):
    Tester Connection
    		Closer Position
    		Specified Condition
    1 - 3
    		A, B, E and F
    		Below 1 Ω
    1 - 3
    		C and D
    		10 kΩ or higher

    Standard resistance (Closer switch):
    Tester Connection
    		Closer Position
    		Specified Condition
    1 - 5
    		B and D
    		Below 1 Ω
    1 - 5
    		A, C, E and F
    		10 kΩ or higher
