PSD Not Fully Closed (Module Commanded Successfully)

Causes
- Obstruction in door track or latch preventing full travel
- Faulty door position/limit switch or sensor
- Damaged or misadjusted latch or striker
- Weak or failing door motor/actuator or high friction in mechanism
- Intermittent or open wiring/connectors between PSD module and door sensors/actuator
- Incorrect calibration or lost alignment of PSD position sensor
Symptoms
- Sliding door stops before fully closed or reopens
- Interior dome light or door-ajar indicator remains on
- Chime or dash message indicating door open
- Door cannot be locked using remote or auto-lock functions
- Audible motor effort without door movement or abnormal noise
What to check
- Scan for codes and read PSD module freeze frame and data
- Visually inspect door tracks, rollers, latch and striker for debris or damage
- Operate door with scan tool/diagnostic tester and observe behavior
- Check for related fuses and battery voltage during operation
- Inspect connectors and wiring for damage, corrosion, or pin loss at door harness and module
- Manually move door through travel to feel binding points and check latch engagement
Signal parameters
- PSD module commanded-close flag / request on CAN
- Door position sensor raw value (0–5 V or digital counts depending on model)
- Limit/closed switch state (open/closed logic)
- Actuator motor supply voltage (approx battery voltage when commanded)
- Motor current draw (amps) during attempt — elevated at stall
- Battery voltage during operation (should remain near nominal)
Diagnostic algorithm
- Retrieve and record all DTCs and freeze-frame data from PSD and related modules. Note recent events and ignition state.
- Attempt a PSD close cycle while monitoring live data: watch commanded-close flag, position sensor, and closed-limit switch state.
- Clear the code and repeat the operation to verify if code is intermittent.
- Inspect the door path and latch area; remove any obstruction and test operation manually and with the module.
- Inspect and wiggle door harness connectors with door in various positions; check for continuity and short to ground or battery on position/limit switch circuits.
- Measure position sensor voltage or signal counts while cycling the door to confirm the sensor changes and reaches the ‘closed’ value; compare to factory spec.
- Measure motor supply voltage and motor current during a commanded close. High current at low movement suggests mechanical bind or motor problem.
- Check and adjust latch/striker alignment per service manual, lubricate rollers and tracks, and repair any worn components.
- Replace faulty position/limit switch, actuator or wiring as indicated by tests. Relearn/calibrate PSD position if required by manufacturer procedure.
- After repairs, clear codes and verify several cycles under normal conditions. Confirm door fully closes and no new DTCs return.
Likely causes
- Door ajar/limit switch stuck or out of spec
- Mechanical binding at hinge, roller, or latch
- Connector corrosion or broken wire in door harness
- Actuator motor draws excessive current or stalls
- Striker misalignment preventing latch from engaging fully
Fault status
Status
PSD Not Fully Closed — module issued close command successfully but closed-state feedback/sensor did not indicate the door reached fully closed.
