When B2241 appears, the control module has detected abnormal behavior related to Rear Cargo Door Lock Circuit Short to Ground in body electronics and comfort modules.
B2241 Code: Meaning, Symptoms, Causes & Fix
Overview
Symptoms
- battery draw complaints
- related warning lamp illuminated
- module resets or glitches
Common causes
- Open circuit in wiring affecting rear cargo door lock circuit short to ground
- Disconnected or loose connector
- Connector pin damage/corrosion or harness stress near related components
How to diagnose B2241
- Confirm B2241 and capture freeze-frame data with a professional scan tool.
- Inspect wiring, connectors, and grounds related to rear cargo door lock circuit short to ground for obvious defects.
- Use a continuity test from module pin to component to identify opens/high resistance.
- Check for related DTCs to identify the root-cause chain before replacing parts.
- After repair, clear codes and confirm readiness monitors complete without recurrence.
Severity of code B2241
Moderate: This code is moderate severity: the vehicle may still operate, but fault progression can increase repair cost over time.
Can you drive with B2241?
Most vehicles can be driven short-term with B2241, but postpone heavy load/highway driving until repaired.
If the warning lamp is flashing or drivability/safety is affected, avoid driving and diagnose immediately.
How to fix it (step-by-step)
- Repair obvious wiring/connector faults first to prevent repeat parts replacement.
- Address the root fault mode (open) in the rear cargo door lock circuit short to ground circuit/system.
- Apply the required relearn/adaptation procedure if specified by service information.
- Road-test and verify B2241 remains cleared under the conditions that originally set the code.
Fix options
- Repair open circuit and secure connector lock.
- Restore continuity and verify pin tension.
- Clear DTCs and verify with live data and completed drive cycle.
Typical repair cost
$160-$850
Common mistakes when diagnosing B2241
- Replacing parts without verifying voltage, ground, and signal integrity first.
- Ignoring related stored/pending codes that indicate upstream faults.
- Skipping post-repair verification drive cycle and readiness checks.
B2241 in common vehicles
B2241 appears across makes such as Mazda, Subaru, Lexus, Jeep. Failure patterns differ by platform: wiring routes, software calibration, and component supplier revisions can change root cause.
