U1405 – Invalid Data Received from Anti-lock Brake System (ABS) Control Module.
The ODBII code U1405 indicates that the vehicle’s control module has received invalid or corrupted data from the Anti-lock Brake System (ABS) control module, which may affect the vehicle’s braking performance and stability.
The severity of ODBII code U1405 is generally considered moderate.
Common Causes For: U1404 Invalid Data Received from Transmission Control Module (TCM).
- Faulty ABS control module
- Corrupted data communication between modules
- Damaged wiring or connectors
- Low battery voltage or poor electrical connections
- Faulty wheel speed sensors
- Software issues or programming errors in the ABS module
- Grounding issues in the ABS system
Common misdiagnosis for U1405 Invalid Data Received from Anti-lock Brake System (ABS) Control Module.
- Faulty ABS Control Module
- Wiring issues or shorts in the ABS circuit
- Faulty wheel speed sensors
- Incorrectly calibrated or malfunctioning speedometer
- Issues with the Engine Control Module (ECM)
- Problems with the vehicle’s communication network (CAN bus)
- Faulty brake pedal position sensor
- Incorrectly diagnosed brake system issues
- Battery or charging system problems

Common Troubleshooting Steps
When dealing with the OBD-II code U1405, which indicates “Invalid Data Received from Anti-lock Brake System (ABS) Control Module,” 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 trouble codes that may be present. Codes related to the ABS or other systems can provide additional context.
- Inspect Wiring and Connectors: **Visual Inspection: Check the wiring and connectors between the ABS module and the vehicle’s computer (ECM). Look for signs of damage, corrosion, or loose connections.
- **Connector Pins: Ensure that the pins in the connectors are not bent or corroded.
- Check the ABS Module: **Functionality: Ensure that the ABS module is functioning correctly. If possible, perform a self-test of the ABS system.
- **Power and Ground: Verify that the ABS module is receiving the correct power and ground signals. Use a multimeter to check voltage and ground continuity.
- Inspect the CAN Bus: **Communication Issues: Since U1405 is a communication-related code, check the Controller Area Network (CAN) bus for issues. Look for shorts, opens, or other faults in the wiring.
- **Termination Resistors: Ensure that the CAN bus termination resistors are present and functioning correctly.
- Check for Software Updates: **ECM/ABS Module Updates: Check if there are any software updates available for the ABS module or the vehicle’s ECM. Sometimes, manufacturers release updates to fix known issues.
- Test the ABS Module: If the above steps do not resolve the issue, consider testing or replacing the ABS module. This may require specialized equipment or professional assistance.
- Clear Codes and Test Drive: After performing the checks and repairs, clear the trouble codes using the OBD-II scanner and take the vehicle for a test drive to see if the code returns.
- Consult Technical Service Bulletins (TSBs): Look for any TSBs related to the specific make and model of the vehicle. Manufacturers may have issued bulletins regarding known issues with the ABS system.
- Seek Professional Help: If you are unable to resolve the issue after these steps, it may be best to consult a professional mechanic or technician who has experience with ABS systems and OBD-II diagnostics.Conclusion Troubleshooting OBD-II code U1405 involves a systematic approach to check for communication issues between the ABS module and the vehicle’s computer. By following these steps, you can identify and potentially resolve the underlying problem.
