Pinpoint Test K: The Power Liftgate Does Not Operate Correctly - Closes (With a Continuous Chime) Immediately After a Power Open

Normal Operation

After the Liftgate/Trunk Module (LTM) has performed a power open operation, power is removed from the clutch and drive motor. The LTM (Liftgate/Trunk Module) briefly continues to monitor the position of the liftgate. If excessive movement in the closed direction is detected, power is reapplied to the clutch and a continuous chime is initiated and remains on as the liftgate is automatically power closed.

If the excessive closing movement is detected on 11 successive power open requests, DTC B201A is set and power liftgate operation is disabled until the DTC is cleared.

- DTC 201A (Power System Disabled Due to High Manual Closing Speed)- This DTC is set when the LTM (Liftgate/Trunk Module) detects excessive closing movement on 11 successive power open requests. When DTC 201A is set, power liftgate operation is disabled until the DTC is cleared.

This pinpoint test is intended to diagnose the following:

- Excessive weight on the liftgate (for example: bike rack or snow and ice)

- Power liftgate full open position not learned correctly during power liftgate initialization procedure

- Liftgate assist cylinders

- LTM (Liftgate/Trunk Module)

PINPOINT TEST K : THE POWER LIFTGATE DOES NOT OPERATE CORRECTLY - CLOSES (WITH A CONTINUOUS CHIME) IMMEDIATELY AFTER A POWER OPEN

K1 RETRIEVE ALL CMDTCs (Continuous Memory Diagnostic Trouble Codes) IN ALL MODULES

- Ignition ON.

- Enter the following diagnostic mode on the scan tool: Self Test- ALL CMDTCs (Continuous Memory Diagnostic Trouble Codes).

Is DTC B201A retrieved from the LTM (Liftgate/Trunk Module)?

Yes
CLEAR all Continuous Memory Diagnostic Trouble Codes (CMDTCs). GO to K2.

No
GO to K2.

K2 CHECK THE LIFTGATE ASSIST CYLINDERS

- Verify there is no excessive weight on the liftgate (for example: bike rack or snow and ice).

- Turn the power liftgate OFF (disable) from the message center.

- Operate the liftgate manually to verify the liftgate assist cylinders hold the liftgate open.

Did the liftgate assist cylinders hold the liftgate open correctly?

Yes
RE-INITIALIZE the power liftgate. REFER to Power Liftgate Initialization . TEST the system for normal operation.

If DTC B201A returns or power liftgate still closes (with a continuous chime) immediately after a power open, INSTALL a new LTM (Liftgate/Trunk Module). REFER to Liftgate/Trunk Module (LTM) . INITIALIZE the power liftgate. REFER to Power Liftgate Initialization . TEST the system for normal operation.

No
INSTALL a new liftgate assist cylinders. RE-INITIALIZE the power liftgate. REFER to Power Liftgate Initialization . TEST the system for normal operation.
