All Doors Fail To Lock From One Switch

  1. Connect scan tool to Data Link Connector (DLC). Turn ignition switch to ON position. Read and record any body related DTCs present. If scan tool displayed any Power Door Lock (PDL) system related DTCs, go to appropriate procedure for DTC message(s) displayed. See SYMPTOM INDEX DIRECTORY  table. If scan tool does not display any PDL system related DTCs, go to next step.
  2. On Dakota 2-door models, go to next step. On Dakota 4-door and Durango models, go to step  5 .
  3. Actuate all PDL switches to verify which PDL is faulty. If driver's PDL switch locked and unlocked doors correctly, replace passenger's PDL switch. Perform BODY VERIFICATION TEST  . If driver's PDL did not actuate door lock correctly, go to next step.
  4. Disconnect driver's and passenger's PDL switch harness connector. Using DVOM, measure resistance of PDL output circuit between driver's PDL switch connector Orange/Violet wire terminal and passenger's PDL switch connector Light Green/Black wire terminal. If reading is less than 5 ohms, replace driver's PDL switch. If reading is 5 ohms or more, repair open in Orange/Violet wire between driver's PDL switch connector and in-line harness connector (located above passenger's door hinge) or repair open in Light Green/Black wire between in-line connector and passenger's PDL switch connector. Perform BODY VERIFICATION TEST  .
  5. On Dakota 4-door and Durango, actuate all PDL switches to verify which PDL switch is faulty. If driver's PDL switch locked and unlocked doors correctly, go to next step. If driver's door PDL switch does not lock and unlock doors correctly, go to step  7 .
  6. Turn ignition switch to OFF position. Disconnect CTM connector C2. Disconnect passenger's PDL switch harness connector. Measure resistance of door lock switch sense circuit (Orange/Violet wire) between CTM connector C2 terminal No. 4 and passenger's PDL switch connector. If reading is less than 5 ohms, replace faulty passenger's PDL switch. Perform BODY VERIFICATION TEST  . If reading is 5 ohms or more, locate and repair open in Orange/Violet wire between CTM and passenger's PDL switch connector. Perform BODY VERIFICATION TEST  .
  7. Turn ignition switch to OFF position. Disconnect CTM connector C2. Disconnect driver's PDL switch harness connector. Measure resistance of door lock switch sense circuit (Orange/Violet wire) between driver's PDL switch connector and CTM connector C2 terminal No. 4. If reading is less than 5 ohms, replace driver's PDL switch. Perform BODY VERIFICATION TEST  . If reading is 5 ohms or more, repair open in Orange/Violet wire between CTM and driver's PDL switch connector. Perform BODY VERIFICATION TEST  .
