PINPOINT TEST H : The Power Liftgate Closes (With a Continuous Chime) Immediately After a Power Open: Notes
Normal Operations and Fault Conditions
After the LTM has performed a power open operation, voltage is removed from the drive motor. The LTM briefly continues to monitor the position of the liftgate. If excessive movement in the closed direction is detected, voltage is reapplied to the motor and a continuous chime is initiated and remains on as the liftgate is automatically closed.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B201A | Power System Disabled Due to High Manual Closing Speed | A continuous memory and on-demand DTC that sets when the LTM detects excessive closing movement on 11 successive power open requests. When DTC B201A sets, power liftgate operation is disabled until the DTC is cleared. |
