Incomplete Latch Cinch - Pawl Switch Failure
NOTE:
This DTC will only set after door cinch operation after 4-second time-out function. Conditions to set DTC may be difficult to reproduce.
NOTE:
After making any repairs, perform BODY VERIFICATION TEST
under VERIFICATION TESTS.
- Using scan tool, record and erase DTCs. Turn ignition off. Wait 10 seconds. Turn ignition on. Operate power liftgate several times if possible. Recheck for DTCs. If INCOMPLETE LATCH CINCH - PAWL SWITCH FAILURE resets, go to next step. If INCOMPLETE LATCH CINCH - PAWL SWITCH FAILURE does not reset, system is operating properly at this time. Check for intermittent poor connections or faulty circuits.
- Visually inspect liftgate for proper alignment, damaged strikers, damaged latches or obstructions. Repair as necessary. If possible, check operation of liftgate on a known-good vehicle. If liftgate effort is excessive, diagnose power liftgate by symptom. See TROUBLE SHOOTING in POWER SLIDING DOORS & LIFTGATE - CARAVAN, TOWN & COUNTRY, & VOYAGER article. If liftgate effort is not excessive, go to next step.
- Using scan tool, select INPUTS/OUTPUTS and monitor PAWL SWITCH state. Open liftgate completely. Using a screwdriver, manually move liftgate cinch/release motor latch to first click (detent) while observing DVOM. Repeat procedure several times while moving liftgate to different positions and wiggling wiring harness. If PAWL SWITCH state changes every time liftgate cinch/release motor latch is manually moved, go to next step. If PAWL SWITCH state does not change every time liftgate cinch/release motor latch is manually moved, go to step 6 .
- Turn ignition off. Disconnect liftgate cinch/release motor connector. See Figure . To access connector, door panel will need to be removed. For removal and installation procedures, see POWER SLIDING DOOR MODULE under REMOVAL & INSTALLATION. Using a test light connected to battery voltage, probe liftgate cinch/release motor connector terminal No. 4 (Black/Gray wire). Wiggle wire with test light connected. If test light is illuminated steady and bright, go to next step. If test light flickers, is not illuminated or is dim, repair open in Black/Gray wire between liftgate cinch/release motor and ground. See WIRING DIAGRAMS in POWER SLIDING DOORS & LIFTGATE - CARAVAN, TOWN & COUNTRY, & VOYAGER article.
- Disconnect Power Liftgate Module (PLGM) connector C2. See Figure . To access connector, left rear trim will need to be removed. See POWER LIFTGATE MODULE under REMOVAL & INSTALLATION. Using DVOM, measure resistance of Orange/Gray wire between PLGM connector C2 terminal No. 1 and liftgate cinch/release motor connector terminal No. 7. See Figure . Wiggle wiring harness with DVOM connected. If resistance is steady at 5 ohms or less, replace PLGM. If resistance is greater than 5 ohms or varies, repair open in Orange/Gray wire between liftgate cinch/release motor and PLGM.
- Turn ignition off. Disconnect liftgate cinch/release motor connector. See Figure . To access connector, door panel will need to be removed. For removal and installation procedures, see POWER SLIDING DOOR MODULE under REMOVAL & INSTALLATION. Disconnect Power Liftgate Module (PLGM) connector C2. See Figure . To access connector, left rear trim will need to be removed. See POWER LIFTGATE MODULE under REMOVAL & INSTALLATION. Using DVOM, measure resistance between ground and PLGM connector C2 terminal No. 13 (Orange/Yellow wire). See Figure . Wiggle wiring harness with DVOM connected. If resistance is greater than 1000 ohms, go to next step. If resistance is 1000 ohms or less or varies, repair short to ground in Orange/Yellow wire.
- Using DVOM, measure resistance between PLGM connector C2 terminals No. 13 (Orange/Yellow wire) and No. 20 (Black/Light Green wire). Wiggle wiring harness with DVOM connected. If resistance is steady at greater than 1000 ohms, replace liftgate cinch/release motor. If resistance is 1000 ohms or less or varies, repair short between Black/Gray and Orange/Yellow wires between liftgate cinch/release motor and PLGM.
