The check engine light on your Ski-Doo comes on, and the search for a Ski-Doo fault codes list starts. Trouble is, forum lists are often old, incomplete or for a different vehicle. The basics of reading the light are covered in reading the Ski-Doo and Lynx check engine light. This post goes further: how BRP codes are built, why the same code can mean different things and real examples from the official list.
Ski-Doo Fault Codes: How BRP Codes Are Built
BRP uses the same code system on Ski-Doo and Lynx as on Sea-Doo and Can-Am. Every code is one letter plus four characters. The letter tells you where the fault comes from:
- P for engine and powertrain: sensors, injection, ignition, temperature, voltage.
- C for chassis.
- B for body, cluster and switches, on a sled for example heated grips and buttons.
- U for network and communication between control units.
The current official BRP list has 1,858 codes. Then there's the status: active means the fault is present right now. Stored means it happened and is still in memory. That makes a big difference when you troubleshoot.
Why the Same Code Can Mean Different Things
A code never stands on its own. It belongs to the control unit that reports it and to the vehicle that unit sits in. That's why the BRP list shows several meanings for many codes. P0301 is a good example: depending on the engine it means a misfire on cylinder 1, on the rear cylinder on the PTO side, or in one variant even cylinder 3. If all you have is the number, you don't know which cylinder it's talking about.
Guessing with forum lists gets you nowhere. The app reads the plain-language text straight from the control unit, with status and, for many codes, a possible cause and check steps. For how codes are split across the ECM, cluster and other control units, see understanding DTCs by control unit.
Ski-Doo 850 Fault Codes: Is There a Separate List?
Many riders search for Ski-Doo 850 fault codes or a 900 ACE list. The official BRP list isn't split by engine. The 600 and 850 E-TEC and the 600 and 900 ACE, turbo included, all report codes in the same system. Which codes can show up on your sled depends on which parts it has. E-RAVE exhaust valve codes only matter on engines with that valve, and wastegate codes only on turbo engines.
Examples from the Official BRP List
A selection of codes that can matter on a snowmobile, with meanings from the BRP list, cleaned up for readability.
| Code | Group | BRP meaning |
|---|---|---|
| P0217 | Engine | Coolant overheat, on some control units with torque reduction |
| P0562 | Engine | Battery or system voltage too low |
| P0335 | Engine | Crankshaft position sensor signal error, not plausible or intermittent |
| P1326 | Engine | Knock sensor 1 maximum error reached, or high detonation detected on the MAG side |
| P1476 | Engine | E-RAVE valve does not reach middle position |
| P0513 | Engine | DESS key invalid |
| B2D50 | Body | Connector A, pin 20 overcurrent or open circuit, on some control units the heated grips output |
| U0100 | Network | Loss of communication with the engine control module (ECM) |
P1326 shows why the plain text matters: one meaning is an electrical knock sensor fault, the other is actual detonation. Two completely different jobs. U0100 is the classic loss of comm with the ECU. Start with connectors, grounds and battery voltage.
Check Engine Light: Work Through It in This Order
- Check battery voltage. Low voltage triggers follow-up faults.
- Read the fault memory of every control unit, not just the ECM.
- Watch the status: active codes first, stored codes after.
- Check connectors and wiring in the affected area for moisture and corrosion.
- Cross-check with live data such as engine temperature, voltage or throttle.
- Clear codes only after the repair, then confirm with a test ride.
Clearing a code is not a repair. If the cause is still there, the code comes back, often on the very next start.
A Ski-Doo Diagnostic Tool on Your Phone
With M-JET DIAGNOSTIC you read the fault memory of the ECM, the cluster and other control units over Bluetooth on your phone. It's a fault code reader and more: every code shows up in plain language with its status, many with a possible cause and check steps. You also get up to 180 live values depending on the ECU, plus component tests for coils, injectors and the fuel pump. If your sled is also cutting power, read Ski-Doo and Lynx limp mode.
Frequently asked questions
Where can I find a reliable Ski-Doo fault codes list?
The official BRP list is the only reliable source. Which meaning applies to your sled is shown in the app, straight from the control unit.
What if my code isn't in the list?
It may come from an older control unit, a different vehicle class, a misread or a forum list. Read the plain-language text straight from the sled instead of guessing a meaning.
Will the check engine light go off after I clear the code?
Yes, but it only stays off if the cause is fixed. Otherwise the control unit sets the fault again.
