What Does B2352 Mean?
This code indicates that the Body Control Module (BCM) has detected an unintended voltage source (battery voltage) present on the driver memory power switch indicator circuit when it should not be present. The memory seat system's indicator light circuit is experiencing a short to battery voltage, causing the indicator to receive constant power. This electrical fault affects the driver seat memory system's feedback and control functions.
Common Causes
40%
Damaged or chafed wiring harness between the BCM and driver seat memory switch, creating direct contact with battery voltage wire
30%
Faulty driver seat memory power switch with internal short circuit to battery voltage
20%
Water intrusion or corrosion in door panel connectors causing cross-circuit short to power
10%
Failed Body Control Module with internal circuit fault on memory switch indicator driver circuit
Diagnostic Steps
1
Step 1: Disconnect the driver seat memory switch connector and measure voltage on the indicator circuit pin at the harness side using a digital multimeter. Should read 0V with switch disconnected; if battery voltage is present, wiring harness has short to power
2
Step 2: Visually inspect all wiring from the seat switch through the door jamb to the BCM for chafing, pinch points, or damaged insulation. Pay special attention to areas where harness flexes or contacts metal edges
3
Step 3: With switch still disconnected, check continuity between the indicator circuit wire and known battery voltage sources in the door panel. Resistance should be infinite (open circuit); any continuity indicates short location
4
Step 4: If wiring tests good, reconnect switch and back-probe the indicator circuit while operating the memory functions. Voltage should pulse or modulate based on switch position; constant battery voltage indicates failed switch
5
Step 5: Inspect all related connectors for corrosion, bent pins, or moisture. Clean with electrical contact cleaner and apply dielectric grease to prevent future corrosion
6
Step 6: After repairing identified fault, clear codes and cycle memory seat functions multiple times while monitoring indicator circuit voltage to confirm proper operation between 0V and switched voltage only during activation

The most common cause of B2352 (Driver Memory Power Switch Indicator Circuit Short to Battery) is: Damaged or chafed wiring harness between the BCM and driver seat memory switch, creating direct contact with battery voltage wire
Typical repair costs for B2352 range from $120 to $650, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to continue driving as this only affects the memory seat indicator function and does not impact vehicle operation or safety systems. Repair at convenience, though prolonged short circuit could potentially drain battery or damage BCM over extended time.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B2352 to identify the root cause.
