U2467 – refers to a communication issue related to the Battery Energy Control Module (BECM).
The ODBII code U2467 indicates a communication issue between the Battery Energy Control Module (BECM) and other vehicle control modules, suggesting a malfunction in data transmission or connectivity.
The severity of ODBII code U2467 is generally considered moderate to high.
Common Causes For: U2466 U2466: BECM Communication Error – Invalid Data Received
- Faulty Battery Energy Control Module (BECM)
- Damaged wiring or connectors in the communication circuit
- Corroded or loose electrical connections
- Malfunctioning powertrain control module (PCM)
- Software issues or programming errors
- Low battery voltage or weak battery
- Interference from aftermarket accessories or modifications

Common Troubleshooting Steps
When dealing with OBD-II code U2467, which indicates a communication issue related to the Battery Energy Control Module (BECM), there are several common troubleshooting steps you can follow to diagnose and potentially resolve the issue. Here’s a structured approach:
- Check for Additional Codes: Use an OBD-II scanner to check for any other related trouble codes. This can provide more context and help identify if there are other issues affecting the BECM.
- Inspect Wiring and Connectors: **Visual Inspection: Check the wiring harness and connectors associated with the BECM for any signs of damage, corrosion, or loose connections.
- **Repair or Replace: If any damaged wires or connectors are found, repair or replace them as necessary.
- Check Battery and Charging System: **Battery Voltage: Ensure the battery is fully charged and in good condition. A weak battery can cause communication issues.
- **Charging System: Verify that the alternator is functioning properly and that the charging system is providing adequate voltage.
- Inspect the BECM: **Physical Condition: Check the BECM for any signs of physical damage or corrosion.
- **Connections: Ensure that the BECM is securely connected and that all pins are clean and free of corrosion.
- Test Communication Lines: **CAN Bus Testing: Use a multimeter or oscilloscope to check the communication lines (CAN bus) for proper voltage levels and signals.
- **Network Integrity: Ensure that the CAN bus network is intact and that there are no short circuits or open circuits.
- Perform a Hard Reset: Disconnect the battery for a few minutes to reset the vehicle’s electronic systems. Reconnect and see if the code reappears.
- Check for Software Updates: **ECU Updates: Check if there are any software updates available for the BECM or other related modules. Sometimes, manufacturers release updates to fix communication issues.
- Scan for Module Communication: Use a professional-grade scan tool to check if the BECM is communicating with other modules in the vehicle. This can help identify if the issue is isolated to the BECM or if it affects other modules as well.
- Consult Technical Service Bulletins (TSBs): Look for any TSBs related to the BECM or the specific vehicle make and model. Manufacturers may have documented common issues and solutions.
- Replace the BECM (if necessary): If all other troubleshooting steps fail and the BECM is determined to be faulty, consider replacing it. Ensure that the replacement module is compatible with your vehicle.1
- Professional Diagnosis: If you are unable to resolve the issue, consider seeking help from a professional mechanic or dealership that has experience with your vehicle’s make and model. By following these steps, you should be able to identify and potentially resolve the communication issue related to the Battery Energy Control Module (BECM) associated with the U2467 code.
