Incomplete Latch Cinch - No Pawl Transition
NOTE:
After making any repairs, perform BODY VERIFICATION TEST under VERIFICATION TESTS.
NOTE:
This DTC will only set after the cinching operation, This may make it difficult to reproduce.
- With the DRBIII®, record and erase DTC's. Turn the ignition off, wait 10 seconds, then turn the ignition on. Operate the power liftgate several times if possible. With the DRBIII®, read ACTIVE DTCs. If the DRBIII® displays INCOMPLETE LATCH CINCH - NO PAWL TRANSITION, go to the next step. If the DRBIII® does not display INCOMPLETE LATCH CINCH - NO PAWL TRANSITION, inspect the wiring and connectors for an intermittent condition. Operate the door several times and check for any binding or other obstructions.
- Examine the liftgate for proper fit and alignment, lose/hard or torn seals, misaligned latch striker or anything that would cause an obstruction to proper operation. Manually operate the liftgate of a known good vehicle and notice the effort needed to open and close. Compare the effort needed on the disabled liftgate. If it takes more effort to operate the liftgate than it should, refer to the related symptom(s). See POWER SLIDING DOORS & LIFTGATE article. If it does not take more effort to operate the liftgate than it should, go to the next step.
- Disconnect the power liftgate C2 connector. See Figure. Disconnect the Liftgate Cinch/Release Motor connector. See Fig 1. Measure the resistance of the Ground wire between the PLG C2 connector (cavity 20) and the Liftgate Cinch/Release Motor connector (cavity 1). Wiggle the harness while observing the ohmmeter. If the resistance is below 5 ohms, go to the next step. If the resistance is above 5 ohms, repair the ground wire for an open.
- Disconnect the Power Liftgate Module C2 connector. See Figure. Disconnect the Liftgate Cinch/Release Motor connector. See Fig 1. Measure the resistance of the Liftgate Pawl Switch Sense wire between the PLG C2 connector and the Liftgate Cinch/Release Motor connector. Wiggle the harness while observing the ohmmeter. If the resistance is below 5 ohms, go to the next step. If the resistance is above 5 ohms, repair the Liftgate Pawl Switch Sense wire for an open.
- Disconnect the Power Liftgate Module C2 connector. See Figure. Disconnect the Liftgate Cinch/Release Motor connector. See Fig 1. Measure the resistance between ground and the Liftgate Pawl Switch Sense circuit. Wiggle the harness while observing the ohmmeter. If the resistance is below 1000 ohms, repair the Liftgate Pawl Switch Sense wire for a short to ground. If the resistance is above 1000 ohms, go to the next step.
- If there are no possible causes remaining, replace the Pawl Switch (latch assembly). See POWER SLIDING DOORS & LIFTGATE article.
