Pinpoint Test E: The Power Tailgate Reverses During A Power Close Operation

WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

Normal Operation and Fault Conditions
REFER to: Power Tailgate - System Operation and Component Description .

Possible Sources
- Tailgate alignment
- Tailgate striker alignment
- Mechanical binding

E1 CHECK THE RGTM (REAR GATE TRUNK MODULE) LATCH AND PAWL SWITCH PARAMETER IDENTIFICATIONS (PIDS)

Using a diagnostic scan tool, view RGTMPIDs.

Using a diagnostic scan tool, monitor the following RGTMPIDs for RH latch:
- Access the RGTM and monitor the TAILGATE_LCK_SW_INPPID
- Access the RGTM and monitor the TAILGATE_PWL_SWPID

Using a diagnostic scan tool, monitor the following RGTMPIDs for LH latch:
- Access the RGTM and monitor the TAILGATE_LCK_SW_INPPID
- Access the RGTM and monitor the TAILGATE_PWL_SWPID

NOTE: The tailgate is in the primary position when the tailgate is in the full closed position. The tailgate is in the unlatch position when the tailgate is open and completely out of the striker.

Begin with the tailgate in the open position, then slowly close the tailgate to the secondary latch (first click) and then primary latch (second click) positions.

Tailgate Latch State/Position	Forkbolt Secondary Switch (FB1)	Forkbolt Primary Switch (FB2)	Tailgate Pawl Switch	Home/Neutral Switch
Normally Open Circiut	Normally Closed Circiut	Normally Open Circiut	Normally Open Circiut
Fully unlatched	Closed (Compressed)	Open (Compressed)	Closed (Compressed)	Open
Secondary	Open	Open (Compressed)	Open	Open

Do the switch states agree with the table?

Yes

GO to E2

No	GO to Pinpoint Test D

E2 CHECK THE MANUAL OPERATION OF THE TAILGATE
- Ignition ON.
- Turn the power tailgate off (disable) from the message center.
- While manually opening and closing the tailgate, check the tailgate for:
  - Power tailgate motor (should move freely while manually opening and closing tailgate and be securely mounted to the tailgate)
  - Check the suspect RH or LH power tailgate latch (should latch completely)
Does the tailgate open and close correctly?

Yes GO to Pinpoint Test D

No REPAIR as necessary.
