Can-Am off-road vehicles and ATVs are known for their ruggedness and reliability. However, issues with the anti-theft system, specifically the Digitally Encoded Security System (DESS), can sometimes leave you stranded. This comprehensive guide will delve into common Can-Am anti-theft problems, helping you diagnose and potentially fix them.
Common Can-Am Anti-Theft Issues
The most common culprit behind Can-Am anti-theft issues is the DESS system. This system relies on a digitally encoded key to allow the engine to start. If the system doesn’t detect the correct key, it will prevent the engine from starting as a security measure.
Here are some typical symptoms of a Can-Am anti-theft system problem:
- Engine cranks but won’t start. You turn the key, the engine cranks, but it refuses to fire up.
- Clicking sounds from the solenoid or fuel pump. These sounds may indicate that the anti-theft system is preventing power from reaching essential components.
- “Check Engine” light flashing. A flashing check engine light can sometimes point toward an anti-theft system malfunction.
- “Security” or “DESS” warning on the gauge cluster. This is a clear indication that the anti-theft system is triggered and is preventing the vehicle from starting.
Diagnosing Can-Am Anti-Theft Problems
Before you start troubleshooting, it’s crucial to identify if the anti-theft system is indeed the root cause.
Here’s what you can do:
- Check your DESS key. Ensure it’s not damaged and is properly inserted. Try a spare key if you have one.
- Inspect the battery connections. A weak battery or poor connections can disrupt the anti-theft system’s functionality.
- Listen for unusual noises when attempting to start, such as clicking from relays or the fuel pump.

Tools and Equipment for Repair
Addressing Can-Am anti-theft issues often requires specialized diagnostic tools and software. These are essential for reading fault codes, resetting the system, and programming new keys.
Consider these options:
- Can-Am BUDS/BUDS2 Diagnostic Software: This is the dealer-level diagnostic suite for Can-Am vehicles, offering comprehensive diagnostic capabilities, programming functions, and access to technical information.
- Professional Automotive Scanners: High-end automotive scanners compatible with Can-Am vehicles can retrieve fault codes and provide insights into the anti-theft system.
Troubleshooting Steps
Important Note: Attempting to repair or bypass the anti-theft system yourself can be risky and potentially dangerous. If you are not comfortable working with electrical systems or using diagnostic tools, it is highly recommended to seek assistance from a qualified Can-Am dealer or a certified technician.
Here’s a general overview of potential solutions:
-
Key Replacement/Programming: If your DESS key is lost or damaged, you’ll need to get a replacement programmed to your vehicle. This usually requires a trip to a Can-Am dealership.
-
DESS Post Replacement: In some cases, the DESS post (the receiver for the key’s signal) may be faulty and need replacement. This often involves accessing and potentially replacing wiring harnesses.
-
Software Updates/Reflashes: Dealerships can perform software updates or reflashes on your Can-Am’s ECU (Engine Control Unit) to address known anti-theft system glitches.
