What Does B2241 Mean?
This code indicates that the Body Control Module (BCM) has detected a short to ground condition in the rear cargo door lock actuator circuit. The BCM monitors the electrical circuit controlling the rear cargo door lock mechanism and has identified that current is flowing to ground through an unintended path, typically indicating damaged wiring or a faulty lock actuator. This prevents proper operation of the rear cargo door locking system.
Common Causes
45%
Damaged, chafed, or pinched wiring in the rear cargo door harness, typically in the flex area between body and door
30%
Failed rear cargo door lock actuator with internal short to ground
15%
Water intrusion or corrosion in the door lock connector causing short circuit
10%
Faulty Body Control Module output driver circuit
Diagnostic Steps
1
Step 1: Perform visual inspection of the rear cargo door wiring harness, especially in the flex area between door hinge and body. Look for chafed, pinched, or damaged wires with exposed copper contacting ground
2
Step 2: Disconnect the rear cargo door lock actuator connector and measure resistance between the lock actuator control wire at the BCM side and ground using a digital multimeter. Reading should be greater than 10k ohms; less than 10 ohms confirms short to ground in wiring
3
Step 3: If wiring tests normal, reconnect harness and disconnect lock actuator. Measure resistance across actuator terminals. One terminal to ground should show infinite resistance; low resistance (less than 5 ohms to ground) indicates failed actuator
4
Step 4: Inspect lock actuator connector and terminals for water intrusion, corrosion, or bent pins. Clean with electrical contact cleaner and check for proper seal integrity
5
Step 5: If all components test normal, suspect BCM internal driver fault. Test BCM output voltage at connector with actuator disconnected; should show battery voltage when unlocked and ground when locked. Constant ground indicates BCM failure
6
Step 6: After repair, clear codes and cycle the rear cargo door lock multiple times using key fob and interior switch to verify proper operation and confirm no code returns
Estimated Repair Cost

The most common cause of B2241 (Rear Cargo Door Lock Circuit Short to Ground) is: Damaged, chafed, or pinched wiring in the rear cargo door harness, typically in the flex area between body and door
Typical repair costs for B2241 range from $100 to $650, depending on the vehicle, location, and whether you do it yourself or go to a shop.
This is safe to drive as it only affects rear cargo door locking convenience. However, the cargo area may not lock properly, creating a security risk for items stored in the rear cargo area. Repair at earliest convenience to restore proper security function.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B2241 to identify the root cause.
