Can Am Dps Problems

Can-Am ATVs and side-by-sides are renowned for their power and performance, but even these robust machines aren't immune to issues. One common area of concern for Can-Am owners is the Dynamic Power Steering (DPS) system. When the DPS malfunctions, it can make riding difficult, even dangerous, turning what should be an enjoyable off-road adventure into a frustrating experience. Understanding the potential problems with your Can-Am DPS, and how to address them, is crucial for keeping your machine running smoothly and ensuring your safety on the trails.

What Exactly Is Can-Am DPS, Anyway?

Before diving into the potential problems, let’s quickly recap what DPS actually does. Dynamic Power Steering is an electronic system that assists the rider in steering the vehicle. Unlike traditional hydraulic power steering, DPS uses sensors to detect the vehicle's speed and steering input, then adjusts the amount of steering assistance accordingly. This means you get lighter steering at low speeds for easier maneuvering, and firmer steering at higher speeds for improved stability. Can-Am offers different levels of DPS (Min, Med, Max) depending on the model, allowing riders to customize the steering feel to their preference.

Uh Oh, My DPS Light Is On! Common Symptoms and What They Mean

The most obvious sign of a DPS problem is the dreaded DPS warning light illuminating on the dashboard. However, that's just the tip of the iceberg. Here are some other common symptoms you might experience:

Increased Steering Effort: This is perhaps the most noticeable symptom. If your steering suddenly feels much heavier than usual, especially at low speeds, it's a strong indicator that the DPS system isn't working correctly.
Erratic Steering: Instead of smooth and predictable steering, you might experience jerky or inconsistent assistance. The steering might feel light in some spots and heavy in others, making it difficult to maintain a steady course.
Complete Loss of Power Steering: In some cases, the DPS system can fail completely, leaving you with manual steering. This is especially problematic on larger ATVs or side-by-sides, as the steering can become very heavy and difficult to manage.
No Power Steering at Low Speeds: This can be frustrating when navigating tight trails or parking. The system might seem to work fine at higher speeds, but provide little to no assistance when you need it most.
Power Steering Cutting Out Intermittently: The DPS might work for a while, then suddenly stop, only to resume working again later. This intermittent behavior can be unpredictable and dangerous.
Grinding or Whining Noises from the DPS Unit: While not always present, unusual noises coming from the DPS unit itself can indicate a mechanical problem within the system.

Decoding the Trouble Codes: What's Your Can-Am Trying to Tell You?

When the DPS warning light comes on, your Can-Am's computer system stores a Diagnostic Trouble Code (DTC). These codes can provide valuable clues about the nature of the problem. You can retrieve these codes using a diagnostic tool, or sometimes even through the vehicle's display (depending on the model). Here are some common DPS-related DTCs and what they might indicate:

C1073: This code often points to a problem with the torque sensor within the DPS unit. The torque sensor measures the amount of force you're applying to the steering wheel, and if it's faulty, the DPS system won't be able to provide the correct amount of assistance.
C107A: This code usually indicates a problem with the motor within the DPS unit. The motor is responsible for providing the actual steering assistance, and if it's failing, you'll likely experience a loss of power steering.
C107B: This code can relate to an issue with the DPS control module itself. This module is the "brain" of the DPS system, and if it's malfunctioning, it can cause a variety of problems.
C107C: This code often indicates a problem with the power supply to the DPS unit. A low voltage or a faulty connection can prevent the DPS system from working correctly.
C107D: This code can indicate an internal fault within the DPS unit, often related to the motor or associated electronics.

Important Note: These are just a few of the common DPS-related DTCs. Always consult your Can-Am service manual or a qualified technician for accurate diagnosis and repair.

The Usual Suspects: Common Causes of Can-Am DPS Problems

Now that you know the symptoms and potential trouble codes, let's explore the common causes of DPS problems in Can-Am ATVs and side-by-sides:

Low Battery Voltage: The DPS system relies on a stable power supply to function correctly. A weak or dying battery can cause the DPS to malfunction or stop working altogether. Always check your battery voltage first! A healthy battery should read around 12.6 volts when the engine is off.
Loose or Corroded Connections: The DPS system has several electrical connections that can become loose or corroded over time, especially in harsh environments. Inspect all connections related to the DPS unit, including the battery terminals, ground connections, and the connectors on the DPS unit itself.
Faulty Torque Sensor: As mentioned earlier, the torque sensor is a critical component of the DPS system. If it's damaged or malfunctioning, the DPS won't be able to provide the correct amount of steering assistance.
Failing DPS Motor: The DPS motor is responsible for providing the actual steering assistance. Over time, the motor can wear out or fail, leading to a loss of power steering.
Damaged DPS Control Module: The DPS control module is the "brain" of the system. If it's damaged by water, vibration, or electrical surges, it can cause a variety of problems.
Worn or Damaged Steering Components: While not directly related to the DPS unit itself, worn or damaged steering components, such as tie rod ends or ball joints, can put extra stress on the DPS system and contribute to its failure.
Water Intrusion: Can-Am ATVs and side-by-sides are often used in wet and muddy conditions. Water intrusion into the DPS unit can damage the internal components and cause it to malfunction.

Troubleshooting Time: Steps You Can Take to Diagnose the Problem

Before rushing to the dealership, there are several troubleshooting steps you can take to try and diagnose the DPS problem yourself:

Check the Battery Voltage: As mentioned earlier, a low battery is a common cause of DPS problems. Use a multimeter to check the battery voltage.
Inspect Electrical Connections: Carefully inspect all electrical connections related to the DPS system. Look for loose connections, corrosion, or damage. Clean any corroded connections with a wire brush and apply dielectric grease to protect them.
Check Fuses and Relays: Locate the fuses and relays related to the DPS system in your vehicle's fuse box. Check them for any signs of damage or burnout. Replace any blown fuses or faulty relays.
Visually Inspect the DPS Unit: Check the DPS unit itself for any signs of damage, such as cracks, leaks, or corrosion.
Check the Steering Components: Inspect the steering components, such as tie rod ends and ball joints, for any signs of wear or damage.
Retrieve Diagnostic Trouble Codes: Use a diagnostic tool to retrieve any stored DTCs. This can provide valuable clues about the nature of the problem.
Perform a DPS System Reset (If Applicable): Some Can-Am models allow you to perform a DPS system reset through the vehicle's display. Consult your owner's manual for instructions.
