What Does B2300 Mean?
B2300 indicates the Body Control Module (BCM) has detected a fault in the driver seat memory positioning system. This code is triggered when the seat cannot move to or store a previously saved memory position, or when the BCM detects feedback from the seat position sensors that does not match the commanded position. The system monitors seat track position, recline angle, and potentially lumbar/height adjustments depending on vehicle equipment.
Common Causes
35%
Faulty seat track position sensor or potentiometer providing incorrect feedback to BCM
30%
Failed seat motor or gear drive mechanism causing inability to reach commanded position
20%
Damaged or corroded wiring/connectors between seat module and BCM causing signal loss
10%
Faulty seat control module or memory switch assembly
5%
Mechanical obstruction or binding in seat track preventing full range of motion
Diagnostic Steps
1
Step 1: Perform visual inspection of driver seat for physical obstructions, damaged tracks, or binding. Manually move seat through full range of motion to verify smooth operation and check for unusual resistance or noise.
2
Step 2: Inspect all wiring harnesses and connectors under the driver seat for damage, corrosion, pinching, or disconnection. Check ground connections for integrity and clean/repair as needed. Use multimeter to verify 12V power supply to seat motors and continuity through position sensor circuits.
3
Step 3: Use scan tool to access live data from seat position sensors while manually moving seat through its range. Compare actual sensor voltage/resistance values against factory specifications to identify faulty position sensors or potentiometers.
4
Step 4: Command seat movement using scan tool bi-directional controls to test each motor independently (track, recline, height, lumbar if equipped). Listen for motor operation and observe if seat moves to commanded positions. Measure motor current draw to identify weak or binding motors.
5
Step 5: If motors and sensors test good, test seat control module by checking for proper voltage output signals to motors during commanded movements. Verify module receives correct signals from memory switches.
6
Step 6: Clear codes, re-initialize seat memory system per manufacturer procedure, program new memory positions, and verify system operates correctly through multiple memory recall cycles to confirm repair.

The most common cause of B2300 (Seat Driver Memory Position Error) is: Faulty seat track position sensor or potentiometer providing incorrect feedback to BCM
Typical repair costs for B2300 range from $150 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to continue driving as this is a comfort feature fault that does not affect vehicle operation or safety systems. Repair can be scheduled at convenience, though proper seat positioning is important for driver comfort and airbag effectiveness.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B2300 to identify the root cause.
