Let's face it, the thrill of tearing through trails on your Can-Am is unmatched. But that adrenaline rush can quickly turn into frustration when your power steering decides to take a vacation. Power steering issues can not only make your ride significantly harder but can also be a safety hazard. Understanding the potential problems, their causes, and how to address them is crucial for keeping your Can-Am performing its best and ensuring you stay safe on the trails.

What's the Deal With Can-Am Power Steering?

Can-Am, like many modern UTV and ATV manufacturers, utilizes Electronic Power Steering (EPS). EPS systems use sensors to detect the amount of force you're applying to the steering wheel and then an electric motor assists you, making turning easier, especially at low speeds or when navigating rough terrain. This system is a complex blend of electronics and mechanics, which, while generally reliable, can be prone to specific issues. Unlike traditional hydraulic power steering, EPS systems don't rely on fluid pressure, reducing the chance of leaks but introducing a whole new set of potential problems.

Common Can-Am Power Steering Problems: A Troubleshooter's Guide

Okay, so your Can-Am's power steering is acting up. Where do you even begin? Let's break down some of the most frequently encountered problems and how to diagnose them.

  • No Power Steering Assist At All: This is arguably the most frustrating scenario. You turn the key, the engine starts, but the steering wheel feels like you're wrestling a bear.

    • Possible Causes: A blown fuse is often the simplest explanation. Check your owner's manual to locate the EPS fuse and inspect it for damage. A faulty EPS module, the "brain" of the system, could also be the culprit. Damaged wiring or connections between the EPS module, sensors, and motor can also cause a complete loss of assist. Lastly, a failing EPS motor itself will prevent the system from assisting.
    • Troubleshooting Steps: Start with the fuse. If the fuse is blown, replace it with one of the correct amperage. If it blows again immediately, there's likely a short circuit somewhere in the system. Next, visually inspect the wiring harness for any obvious damage – frayed wires, loose connections, or corrosion. If you have access to a multimeter, check for voltage at the EPS motor connector. If there’s power, the motor might be the problem. If there's no power, the issue is upstream in the wiring or the EPS module. Unfortunately, diagnosing a faulty EPS module often requires specialized diagnostic equipment.

  • Intermittent Loss of Power Steering: This is a tricky one because the problem comes and goes, making it harder to pinpoint.

    • Possible Causes: Loose wiring connections are a prime suspect here. As the vehicle vibrates, a loose connection can momentarily break the circuit, causing the power steering to cut out. Overheating of the EPS motor or module can also lead to intermittent issues. Some Can-Am models have a thermal protection feature that shuts down the EPS system if it gets too hot. A failing speed sensor can also cause intermittent problems, as the EPS system uses vehicle speed to adjust the level of assist.
    • Troubleshooting Steps: Carefully inspect all wiring connections related to the EPS system. Pay close attention to connectors near the EPS module, motor, and speed sensors. Clean any corroded connections with electrical contact cleaner. Check the EPS motor and module for signs of overheating after a ride. If overheating is suspected, ensure the cooling fan (if equipped) is functioning correctly. Use a diagnostic tool to read the speed sensor signal and see if it is dropping out intermittently.

  • Power Steering Assist Only Works in One Direction: Turning left is easy, but turning right feels like a workout, or vice versa. This is a clear indication of something specific going wrong.

    • Possible Causes: This is less common, but could be caused by internal damage to the EPS motor itself, where one set of windings is failing. It could also be related to the torque sensor within the EPS unit that measures the driver's input, if it’s sending an uneven signal.
    • Troubleshooting Steps: Check the EPS motor wiring and connections on both sides. Ensure there are no obvious breaks or shorts. This problem often requires professional diagnostics to pinpoint the internal fault within the EPS unit.

  • Excessive Power Steering Assist (Too Sensitive): While having power steering is great, too much assist can make the vehicle feel twitchy and unstable, especially at higher speeds.

    • Possible Causes: A faulty speed sensor is a likely cause. The EPS system uses vehicle speed to reduce the amount of assist at higher speeds, providing a more stable feel. If the speed sensor is malfunctioning, the EPS system might think the vehicle is traveling much slower than it actually is, resulting in excessive assist. A miscalibration of the EPS system can also lead to over-sensitivity.
    • Troubleshooting Steps: Check the speed sensor wiring and connections. Use a diagnostic tool to verify the speed sensor signal is accurate. Recalibrating the EPS system using a Can-Am diagnostic tool might resolve the issue.

  • Power Steering Assist is Weak (Not Enough Assist): You have some power steering, but it's not providing enough assistance, making turning difficult, especially at low speeds or when encountering obstacles.

    • Possible Causes: Low battery voltage can affect the performance of the EPS motor. Ensure your battery is fully charged and in good condition. A worn-out EPS motor might not be able to provide sufficient assist. This can happen over time as the motor brushes wear down.
    • Troubleshooting Steps: Check your battery voltage with a multimeter. A fully charged battery should read around 12.6 volts. Have your battery load tested to ensure it can handle the electrical load of the EPS system. Inspect the EPS motor for signs of wear or damage.

The Importance of a Clean Electrical System

It's easy to overlook, but a clean and well-maintained electrical system is crucial for the proper functioning of your Can-Am's EPS. Corroded battery terminals, loose ground connections, and damaged wiring can all contribute to power steering problems. Regularly inspect your electrical system and clean any corroded connections with a wire brush and electrical contact cleaner. Ensure all ground connections are tight and secure.

When to Call in the Pros

While many power steering problems can be diagnosed and fixed with basic tools and a bit of know-how, some issues require specialized equipment and expertise. If you're not comfortable working on your vehicle's electrical system or if you've tried the troubleshooting steps above and the problem persists, it's best to take your Can-Am to a qualified mechanic. They have the diagnostic tools and experience to accurately identify the root cause of the problem and perform the necessary repairs.

Preventative Maintenance: Keeping Your EPS Happy

The best way to avoid power steering problems is to perform regular preventative maintenance. This includes:

  • Regularly Inspecting Wiring: Check for any signs of damage, corrosion, or loose connections.
  • Keeping Battery Terminals Clean: Use a wire brush and battery terminal cleaner to remove any corrosion.
  • Ensuring Proper Battery Voltage: Regularly check your battery voltage and have it load tested periodically.
  • Avoiding Deep Water Crossings: Water can damage the EPS motor and module. If you must cross deep water, ensure the EPS components are properly sealed and protected.
  • Following Can-Am's Recommended Maintenance Schedule: Adhere to the recommended maintenance schedule for your specific Can-Am model.

Frequently Asked Questions

  • Why did my Can-Am power steering suddenly stop working? A blown fuse is a common cause. Check your owner's manual to locate and inspect the EPS fuse.
  • Can I upgrade my Can-Am's power steering? Yes, aftermarket EPS kits are available that can provide more assist or improve performance.
  • Is it safe to drive my Can-Am with faulty power steering? It depends on the severity of the problem. Reduced or intermittent assist can make steering difficult and potentially dangerous.
  • How much does it cost to replace a Can-Am EPS module? The cost can vary depending on the model, but expect to pay several hundred dollars for the module itself.
  • Can I recalibrate my Can-Am EPS system myself? Some basic calibrations can be performed using aftermarket diagnostic tools, but complex calibrations usually require a Can-Am dealer.

Conclusion

Dealing with power steering problems on your Can-Am can be a frustrating experience, but with a little knowledge and the right tools, you can often diagnose and fix the issue yourself. Remember to prioritize preventative maintenance to keep your EPS system running smoothly for years to come.
