U1407 – Invalid Data Received from Anti-lock Brake System (ABS) Control Module.

The ODBII code U1407 indicates that the vehicle’s control module has received invalid or corrupted data from the Anti-lock Brake System (ABS) control module.

The severity of ODBII code U1407 is generally considered moderate.

Common Causes For: U1406 Invalid Data Received from Anti-lock Brake System (ABS) Control Module.

• Faulty ABS control module
• Corrupted data communication
• Damaged wiring or connectors
• Poor ground connections
• Faulty vehicle speed sensor
• Software issues or updates needed
• Intermittent electrical issues
• Low battery voltage or power supply problems

Common misdiagnosis for U1407 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 diagnosed transmission issues
• Faulty engine control module (ECM)
• Issues with the powertrain control module (PCM)
• Problems with the vehicle’s communication network (CAN bus)
• Incorrectly diagnosed brake system issues
• Battery or charging system problems
• Faulty or corroded connectors in the ABS system

Common Troubleshooting Steps

When dealing with the OBD-II code U1407, 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 main 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: Verify that the ABS module is functioning correctly. This may involve checking for proper operation of the ABS system during a test drive.
• **Power and Ground: Ensure 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: Since U1407 is a communication-related code, check the Controller Area Network (CAN) bus for issues. Look for:
• Short circuits or open circuits in the CAN wiring.
• Interference from other devices or modules.
• Use a scan tool capable of monitoring CAN bus data to check for communication errors.
• Check for Software Updates: Sometimes, the issue can be resolved with a software update for the ABS module or the vehicle’s ECM. Check with the manufacturer for any available updates.
• Perform a System Reset: Clear the trouble codes using an OBD-II scanner and see if the code returns after a test drive. This can sometimes reset communication issues.
• Test the ABS Module: If the above steps do not resolve the issue, consider testing the ABS module itself. This may involve bench testing or replacing the module if it is determined to be faulty.
• Consult Technical Service Bulletins (TSBs): Check for any TSBs related to the U1407 code or ABS issues for your specific vehicle make and model. Manufacturers may have documented solutions for known issues.
• Seek Professional Help: If you are unable to diagnose or resolve the issue, it may be best to consult a professional mechanic or a dealership with experience in your vehicle’s ABS system.Conclusion By following these troubleshooting steps, you can systematically identify and address the cause of the U1407 code. Always ensure safety when working on vehicle systems, especially those related to braking and stability.
