What Does B2301 Mean?
This code indicates the Body Control Module (BCM) has detected a fault in the passenger seat memory position system. The system is unable to properly store, recall, or verify the saved seat positions for the passenger seat. This typically means the seat position sensors are providing inconsistent data, the memory module cannot communicate with the seat motors, or there is a mechanical fault preventing the seat from reaching programmed positions.
Common Causes
35%
Faulty seat position sensor or potentiometer providing incorrect feedback to the BCM
30%
Damaged wiring harness or corroded connectors between seat module and BCM
20%
Failed seat memory control module or integrated seat control unit
10%
Mechanical binding or obstruction in seat track preventing accurate positioning
5%
Low voltage or power supply issue to seat memory system during operation
Diagnostic Steps
1
Step 1: Perform visual inspection of passenger seat track and movement - manually move seat through full range of motion checking for binding, obstructions, debris, or mechanical resistance that could prevent accurate positioning
2
Step 2: Inspect seat wiring harness under the seat for damage, pinching, or wear - check all connectors at seat module and BCM for corrosion, pushed-back pins, or moisture intrusion - repair or clean as needed
3
Step 3: Using a multimeter, check power and ground circuits to the seat memory module with ignition on - verify 12V power supply and clean ground (less than 0.1 ohm resistance to battery negative)
4
Step 4: Access live data stream for seat position sensors - command seat to move to different positions and verify sensor voltage changes smoothly (typically 0.5V to 4.5V range) without dropouts or erratic readings
5
Step 5: Test seat position potentiometers with multimeter by measuring resistance while manually moving seat - resistance should change smoothly without jumps or dead spots (typically 1k-10k ohm range depending on position)
6
Step 6: If all circuits and sensors test good, reprogram or replace seat memory module - clear codes, set new memory positions, cycle through all positions three times, and verify code does not return
Estimated Repair Cost

The most common cause of B2301 (Seat Passenger Memory Position Error) is: Faulty seat position sensor or potentiometer providing incorrect feedback to the BCM
Typical repair costs for B2301 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 only. The seat will still function manually but memory positions may not work properly. No immediate safety risk, but proper seat positioning is important for airbag effectiveness and driver comfort.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B2301 to identify the root cause.
