PINPOINT TEST C : The Power Liftgate Stops in Secondary Latch Position
- C1 CHECK THE MANUAL OPERATION OF THE LIFTGATE
- Turn the power liftgate off (disable) from the message center.
- While manually opening and closing the liftgate, check the liftgate for:
- liftgate/wedge alignment
- strut operation (struts should push liftgate open when beyond half open)
- power liftgate motor (should move freely while manually opening and closing liftgate and be securely mounted to the liftgate and bracket)
- power liftgate latch (should latch completely)
Does the liftgate open and close correctly?
Yes GO to C2. No REPAIR as necessary. - C2 CHECK THE LIFTGATE LATCH AND STRIKER ALIGNMENT
- Inspect the striker and latch for correct alignment.
Is the latch and striker aligned correctly?
Yes GO to C3. No ALIGN the liftgate and striker. Refer to Liftgate Alignment . - C3 CHECK THE DETENT AND FORKBOLT SWITCH PIDs
- Using the scan tool, view LTM PIDs.
- Operate the liftgate manually while monitoring the LTM PIDs :
- Detent Switch Status (DETENTSW)
- Forkbolt Switch Status (FORKBLT_S)
- Forkbolt Secondary Switch (FKSWSEC)
- Begin with the liftgate in the open position, then slowly close the liftgate into each of the latch positions specified by the table below.
Liftgate Latch Position DETENTSW FORKBLT_S FKSWSEC Fully unlatched Inactive Active Active Primary Active Inactive Inactive
Do the switch states agree with the table?
Yes GO to C4. No GO to Pinpoint Test L . - C4 CHECK FOR CORRECT LTM OPERATION
- Ignition OFF.
- Disconnect and inspect all LTM connectors.
- Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary
- Reconnect all the LTM connectors. Make sure they seat and latch correctly.
- Operate the system and determine if the concern is still present.
Is the concern still present?
Yes CHECK OASIS for any applicable TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs address this concern, INSTALL a new LTM. Refer to Liftgate/Trunk Module (LTM) . No The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
