With door latch locked: COM to NO = continuity. If micro switch is abnormal, replace the micro switch. 4. undefined: Check door locking motor resistance. Normal = approximately 2.6 kΩ ±10% (service manual also notes approximately 3.9 kΩ in flow chart — use 2.6-3.9 kΩ range). Abnormal = infinite (open) or below 5Ω (shorted). If abnormal, replace the door locking motor. 5. undefined: Check looseness of CN02 connector. If loose, reconnect and test. 6. undefined: If all components check normal, replace the Main PCB.
