As you drive your Nissan Qashqai, an unexpected message appears on the dashboard: “Chassis Control System Fault.” You might wonder, is it safe to continue driving? What does this warning mean, and how can you fix it?
This comprehensive guide will walk you through everything you need to know about the chassis control system fault in your Nissan Qashqai. We’ll dive into the causes, how to diagnose the problem, and what steps you can take to fix it, whether you’re a DIY enthusiast or prefer to consult a professional.
What is the Chassis Control System in a Nissan Qashqai?
The chassis control system in a Nissan Qashqai is designed to enhance vehicle stability and control. It integrates various systems such as the Anti-lock Braking System (ABS), Electronic Stability Control (ESC), and Traction Control System (TCS) to ensure your vehicle maintains optimal performance, especially in challenging driving conditions.
When this system detects an issue, it triggers the “Chassis Control System Fault” warning, indicating that one or more components may not be functioning correctly.
Common Causes of the Chassis Control System Fault
Several issues can trigger the chassis control system fault in your Nissan Qashqai. Here’s a deeper dive into the most common causes:
1. Corroded Battery Terminals
Corroded battery terminals are a leading cause of chassis control system faults. Corrosion, often caused by moisture or battery acid leakage, can disrupt the electrical connections necessary for the system to function correctly.
Solution: Inspect the battery terminals for any signs of corrosion. If corrosion is present, clean the terminals using a mixture of baking soda and water, or a dedicated battery terminal cleaner. Ensure the terminals are dry before reconnecting.
2. Battery Failure
The battery powers the entire electrical system of your vehicle, including the chassis control system. A failing battery, particularly one older than four years, can lead to insufficient power being supplied to these systems, triggering a fault.
Solution: If your battery is old or struggling to hold a charge, consider replacing it. A professional can test the battery’s health and confirm if it’s the source of the problem.
3. Voltage Drop in the Battery
A significant drop in battery voltage can also cause the chassis control system fault. This often happens due to a failing alternator, leaving the battery undercharged.
Solution: Use a multimeter to check the battery voltage. If it reads below 12.6 volts when the engine is off, the battery may not be fully charged. Consider charging the battery or replacing it if necessary.
4. Loose Battery Terminals
Loose battery connections can prevent the proper flow of electricity, leading to system errors. This is especially common after recent battery maintenance or installation.
Solution: Check the battery terminals to ensure they are securely connected. Tighten any loose connections using a wrench, being careful not to overtighten and damage the terminals.
Diagnosing the Chassis Control System Fault
Diagnosing the exact cause of a chassis control system fault involves a systematic approach:
Step 1: Visual Inspection
Begin with a visual inspection of the battery, terminals, and associated wiring. Look for signs of corrosion, loose connections, or physical damage.
Step 2: Check Battery Voltage
Using a multimeter, check the battery voltage with the engine off and running. This will help you determine if the issue is related to battery health or charging system problems.
Step 3: Scan for Error Codes
If the fault persists, use an OBD-II scanner to check for error codes related to the chassis control system. These codes can provide specific details about which component is malfunctioning, guiding further diagnosis.
Step 4: Professional Diagnosis
If the above steps don’t resolve the issue, consider taking your vehicle to a certified Nissan technician. They have access to advanced diagnostic tools and can perform a more thorough examination of the system.

Can You Drive with a Chassis Control System Fault?
While it may be possible to drive your Qashqai with the chassis control system fault warning, it’s not advisable. The fault could compromise your vehicle’s stability and safety, especially in challenging driving conditions. Ignoring the warning could lead to more severe issues down the line, so it’s best to address it promptly.
Solutions for Chassis Control System Faults
Here are some common solutions you can try to resolve the chassis control system fault:
1. Replace the Battery
If the battery is old or failing, replacing it might resolve the fault. Ensure you install a high-quality battery with the correct specifications for your Qashqai.
2. Fix Loose or Corroded Terminals
Secure any loose battery connections and clean corroded terminals to restore proper electrical flow.
3. Replace Faulty Sensors or Components
If the diagnostic process reveals a specific faulty sensor or component within the chassis control system, replacing it should resolve the fault.
Preventative Maintenance Tips
To avoid encountering this issue in the future, follow these preventative maintenance tips:
- Regular Battery Checks: Test your battery’s voltage every six months to ensure it’s holding a charge and providing adequate power to your vehicle’s systems.
- Keep Terminals Clean: Regularly inspect and clean battery terminals to prevent corrosion from disrupting electrical connections.
- Drive Regularly: If your vehicle sits unused for long periods, the battery may lose its charge. Regular driving helps keep the battery charged and the chassis control system functioning properly.
