U2017 – Driver Side Crash Sensor Communication Fault (Non SCP)

The ODBII code U2017 indicates a communication fault with the driver side crash sensor, suggesting that the sensor is not properly communicating with the vehicle’s control module, and it is not related to the SCP (Serial Communication Protocol).

The severity of ODBII code U2017 is generally considered moderate to high.

Common Causes For: U2016 Signal Link Short to Ground (Non SCP) / From NGV Module

• Faulty driver side crash sensor
• Damaged wiring or connectors
• Poor electrical connections
• Malfunctioning airbag control module
• Corrosion or short circuits in the circuit
• Software issues in the vehicle’s control systems
• Improper installation or replacement of crash sensors

Common misdiagnosis for U2017 Driver Side Crash Sensor Communication Fault (Non SCP)

• Faulty airbag control module
• Damaged wiring or connectors
• Faulty crash sensor
• Software issues or updates needed
• Issues with the body control module (BCM)
• Faulty seat belt pretensioner
• Grounding issues
• Other communication faults in the network

Common Troubleshooting Steps

When dealing with an OBD-II code U2017, which indicates a “Driver Side Crash Sensor Communication Fault (Non-SCP),” it’s important to follow a systematic approach to troubleshoot the issue. Here are common troubleshooting steps:

• 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 multiple issues.
• Inspect Wiring and Connectors: **Visual Inspection: Check the wiring and connectors associated with the driver side crash sensor. Look for signs of damage, corrosion, or loose connections.
• **Connector Pins: Ensure that the pins in the connectors are not bent or corroded.
• Test the Crash Sensor: **Resistance Check: Measure the resistance of the crash sensor using a multimeter. Compare the readings to the specifications in the vehicle’s service manual.
• **Functionality Test: If possible, test the crash sensor with a scan tool that can perform active tests to see if it responds correctly.
• Check the Airbag Module: Inspect the airbag control module for any signs of damage or corrosion.
• Ensure that the module is properly connected and that there are no faults in the module itself.
• Inspect the Ground Connections: Ensure that all ground connections related to the airbag system and crash sensors are clean and secure. Poor ground connections can lead to communication faults.
• Check for Short Circuits: Use a multimeter to check for short circuits in the wiring harness leading to the crash sensor. Look for continuity between wires that should not be connected.
• Scan Tool Data: Use a professional scan tool to monitor live data from the airbag system. Look for any anomalies or irregularities in the data that could indicate a problem.
• Clear Codes and Test Drive: After performing the above checks and repairs, clear the trouble codes and take the vehicle for a test drive to see if the code returns.
• Consult Technical Service Bulletins (TSBs): Check for any TSBs related to the specific make and model of the vehicle. Manufacturers may have issued guidance on common issues related to crash sensor faults.
• Professional Diagnosis: If the issue persists after performing the above steps, consider seeking help from a professional technician or dealership. They may have access to specialized tools and knowledge specific to your vehicle.Safety Note: – Always take necessary precautions when working with airbag systems, as they can be dangerous if mishandled. Disconnect the battery and wait for a period of time before working on the airbag system to ensure that the capacitors are discharged. By following these steps, you should be able to identify and resolve the issue related to the U2017 code.
