What Does B2592 Mean?
This code indicates that a Power Sliding Door (PSD) module successfully received a command to close but the door did not reach the fully closed position. The Body Control Module (BCM) or sliding door control module has detected that despite proper electrical communication and command execution, a physical or mechanical issue is preventing complete closure. This suggests the door mechanism is obstructed, misaligned, or experiencing a sensor/switch failure that prevents confirmation of full closure.
Common Causes
35%
Worn or damaged door latch mechanism, striker misalignment, or latch actuator failure preventing proper engagement
30%
Faulty door closed position sensor or limit switch providing incorrect feedback to the control module
20%
Binding, obstruction, or worn door track/rollers preventing full door travel to closed position
15%
Door control module internal fault or wiring harness issue between door components and control module
Diagnostic Steps
1
Step 1: Perform visual inspection of the power sliding door operation - manually close and open the door while observing for binding, unusual noises, misalignment, or obstructions in the track and roller system. Check door seal interference and panel alignment.
2
Step 2: Using bi-directional controls through the scan tool, command the door to close while carefully observing the latch mechanism engagement. Note if the latch reaches but fails to engage the striker, or stops short of the striker entirely.
3
Step 3: Test the door closed position sensor/limit switch with a multimeter - verify proper voltage signal change when door transitions from open to closed. Compare readings to manufacturer specifications (typically 0-5V range or ground/open circuit change).
4
Step 4: Inspect the door latch assembly and striker for wear, damage, or misalignment. Check striker bolt torque and adjustment. Lubricate latch mechanism with appropriate grease and test operation.
5
Step 5: Check all wiring harness connections at the door latch, position sensors, and control module for corrosion, loose pins, or damage. Pay special attention to flex points where the harness moves with the door.
6
Step 6: After repairs, clear codes, perform multiple open/close cycles using both power and manual operation, then verify code does not return and door latches securely in closed position.

The most common cause of B2592 (PSD Not Fully Closed (Module Commanded Successfully)) is: Worn or damaged door latch mechanism, striker misalignment, or latch actuator failure preventing proper engagement
Typical repair costs for B2592 range from $150 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle is drivable but the sliding door may not secure properly, creating a risk of the door opening during transit and potential occupant ejection hazard. Do not transport passengers in seats adjacent to the affected door until repaired, and avoid highway speeds.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B2592 to identify the root cause.
