Can-Am Outlander owners often seek ways to perform diagnostics and read codes themselves, avoiding trips to the dealership for minor issues. This article explores the possibility of using a standard automotive scan tool to communicate with the BRP EFI system on a Can-Am Outlander. Success would empower owners to clear service messages, read and clear codes, and monitor various parameters.
Understanding the Can-Am ECM Protocol
The Can-Am’s Engine Control Module (ECM) utilizes the KW2000 protocol, which is a variant of ISO9141 in the automotive world. Many automotive scan tools are compatible with ISO9141, suggesting potential compatibility. However, Can-Am also refers to its diagnostic lines as CAN lines, potentially indicating a different protocol altogether. This discrepancy needs further investigation.
Wiring an Automotive Scan Tool to a Can-Am
Based on research, a possible wiring configuration from a standard OBD2 connector to the Can-Am’s 6-pin connector is as follows:
- OBD2 Pin 16 to Can-Am Pin 5: Battery Positive (+)
- OBD2 Pin 4 to Can-Am Pin 3: Battery Negative (-)
- OBD2 Pin 7 to Can-Am Pin 6: ISO9141 K-Line
- OBD2 Pin 15 to Can-Am Pin 1: ISO9141 L-Line
This configuration leaves one wire on the Can-Am connector unaccounted for. This unknown wire connects pins 1 and 2 through a resistor within the connector housing. Its purpose remains unclear.
Troubleshooting Connection Issues
Initial attempts using the above wiring scheme resulted in a brief connection to the ISO9141 protocol, immediately followed by a “Can’t communicate with vehicle” error. Reversing the two communication wires yielded the same result. Further attempts, including tapping into the Black/Green (BG/GN) and White/Black (WT/BG) wires (pins 1 and 2) led to a “Communication Error” on the speedometer display, but the scan tool still failed to connect.
One area of further exploration involves the distinction between “chassis ground” and “signal ground” on the OBD2 connector. Understanding the specific grounding requirements of the Can-Am system might be crucial for successful communication.
Conclusion: The Quest for a DIY Solution Continues
While a definitive solution for using a generic automotive scan tool with a Can-Am Outlander remains elusive, this investigation provides a starting point for further experimentation. Successfully connecting a scan tool would unlock significant diagnostic capabilities for Can-Am owners. However, caution is advised, and further research is necessary to avoid potential damage to the vehicle’s electrical system.
