The OBDSTAR M029 is the IMMO cable for Yamaha jet skis. On the vehicle side, it features the yellow 2-pin connector that connects to the diagnostic port of your jet ski; the other end plugs into the IMMO input of your OBDSTAR programmer.
Yamaha uses a 2-pin diagnostic connector on these watercraft that doesn't fit standard diagnostic ports. This cable converts that connector format to what OBDSTAR programmers expect, allowing the equipment to communicate with the immobilizer module. No data processing occurs in the cable itself — signal transmission is passive.
The cable is designed for immobilizer work, not general engine diagnostics. Which IMMO functions you can perform depends on your device's software version and license level.
KEY BENEFITS
IMPORTANT NOTES
Applications and Features
Access the immobilizer system of your jet ski through the 2-pin connector.
Control units you can reach
- Immobilizer module: the unit where key data and security PIN code are stored.
- Associated components: when replacing the ECU or lock component, module initialization may also be required.
What you can do
- Read key code: retrieve stored key codes from the immobilizer module via the 2-pin connector.
- Add key: program a new key into the IMMO system using existing key data as reference.
- Initialize immobilizer: reset the module, for example after replacing the ECU or a lock component.
- Read PIN code: extract the security PIN code from the IMMO system, which is needed for certain key procedures.
- Important: which of these procedures are available depends on your OBDSTAR programmer's software and license.
