Incomplete Latch Cinch - Ratchet Switch Failure

NOTE: After making any repairs, perform BODY VERIFICATION TEST  under VERIFICATION TESTS.
  1. Turn ignition on. Using scan tool, record and erase DTCs. Turn ignition off. Wait approximately 10 seconds. Turn ignition on. Operate power sliding door several times if possible. Recheck for DTCs. If INCOMPLETE LATCH CINCH - RATCHET SWITCH FAILURE resets, go to next step. If INCOMPLETE LATCH CINCH - RATCHET SWITCH FAILURE does not reset, system is okay at this time. Check for intermittent poor connections or faulty circuits. See WIRING DIAGRAMS in POWER SLIDING DOORS & LIFTGATE - CARAVAN, TOWN & COUNTRY, & VOYAGER article.
  2. Visually inspect sliding door for proper alignment, damaged strikers, damaged latches or obstructions. Repair as necessary. If possible, check operation of sliding door on a known-good vehicle. If sliding door effort is excessive, diagnose power sliding door. See TROUBLE SHOOTING in POWER SLIDING DOORS & LIFTGATE - CARAVAN, TOWN & COUNTRY, & VOYAGER article. If sliding door effort is not excessive, go to next step.
  3. Using scan tool, select INPUTS/OUTPUTS and monitor RATCHET state. Open sliding door completely. Using a screwdriver, manually move sliding door cinch/release motor latch to second click (detent) and release using outside handle while observing DVOM. Repeat procedure several times while moving sliding door to different positions and wiggling wiring harness. If RATCHET state does not change every time sliding door cinch/release motor latch is manually moved, go to next step. If RATCHET state changes every time sliding door cinch/release motor latch is manually moved, replace Power Sliding Door Module (PSDM). See POWER SLIDING DOOR MODULE  under REMOVAL & INSTALLATION.
  4. Turn ignition off. Locate and disconnect sliding door cinch/release motor connector. See Figure . To access connector, door panel will need to be removed. See POWER SLIDING DOOR MODULE  under REMOVAL & INSTALLATION. Using a test light connected to battery voltage, probe sliding door cinch/release motor connector terminal No. 2 (Black/White wire). See Figure . 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/White wire between sliding door cinch/release motor and ground. See WIRING DIAGRAMS in POWER SLIDING DOORS & LIFTGATE - CARAVAN, TOWN & COUNTRY, & VOYAGER article.
  5. Locate and disconnect PSDM connector C1. See Figure . Using DVOM, measure resistance of Orange/Gray wire between PSDM connector C1 terminal No. 1 and sliding door cinch/release motor connector terminal No. 3. See Figure . Wiggle wiring harness with DVOM connected. If resistance is steady at 5 ohms or less, go to next step. If resistance is greater than 5 ohms or varies, repair open in Orange/Gray wire between sliding door cinch/release motor and PSDM.
  6. Disconnect PSDM connector C2. Locate and disconnect sliding door latch sensing switch connector. On left sliding door, using DVOM, measure resistance between sliding door latch sensing switch connector terminals No. 1 (Black/Gray wire) and No. 4 (Black/Gray wire) and PSDM connector C2 terminal No. 20 (Black/Tan wire). See Figure and Figure . On right sliding door, using DVOM, measure resistance between sliding door latch sensing switch connector terminals No. 1 (Black/Yellow wire) and No. 4 (Black/Yellow wire) and PSDM connector C2 terminal No. 20 (Black/Tan wire). On all doors, wiggle wiring harness with DVOM connected. If resistance is steady at 5 ohms or less at both terminals, go to next step. If resistance is greater than 5 ohms or varies at either or both terminals, repair open in ground circuit between PSDM and sliding door latch sensing switch. See WIRING DIAGRAMS in POWER SLIDING DOORS & LIFTGATE - CARAVAN, TOWN & COUNTRY, & VOYAGER article.
  7. Using DVOM, measure resistance of Tan/Orange wire between PSDM connector C2 terminal No. 12 and sliding door latch sensing switch connector terminal No. 3. Wiggle wiring harness with DVOM connected. If resistance is steady at 5 ohms or less, go to next step. If resistance is greater than 5 ohms or varies, repair open in Tan/Orange wire.
  8. Using DVOM, measure resistance between ground and PSDM connector C2 terminal No. 12 (Tan/Orange wire). Wiggle wiring harness with DVOM connected. If resistance is greater than 5 ohms, replace sliding door cinch/release motor. If resistance is 5 ohms or less or varies, repair short to ground in Tan/Orange wire.
