\nThe Jaltest JDC661M is the key programming adapterfor waterscooters fromYamaha. It is a sealed unit 5.2 cmwith a black rectangular connector on the frontyellow pen holder and two flat pins side by side, and on the rear a black round key postA widened head on a narrow neck, onto which the key is presented. It has no cable attached and no 16-pin OBD2 connector; the inscriptionJDC661M is pressed into the housing.\n
\nWhere a diagnostic cablethe diagnostic line opens tofault codes and read measurement values, this article brings the key yourself in the game: The code is read and written to the immobiliser blocking, and for that the item must be physically presented at the post office. This is how you report a new or replacement key on and retrieves a lost unit from memory — work that cannot be done with a standard diagnostic cable. For fault codes and measured values on the same waterscooter, the JDC601A intended. Cojali releases the adapter for the Jaltest Link V8.1 and V9; it falls under Jaltest Marine.\n
ADVANTAGES
IMPORTANT NOTES
Applications and Features
Using this adapter, you can programme with the Jaltest software the keys of the Yamaha water scooter. The immobiliser blockingallows the engine to run only with a key stored in memory, and that memory is precisely what you access with this tool. Belowoperations belong to the Marine coveragevan Jaltest.
Control units you can access
- The waterscooter immobiliser:The system in which key codes are stored and where a key is registered or deregistered.
- The 2-pin connection:The separate connector that Yamaha uses for this purpose, distinct from the standard 3-pin diagnostic socket.
What you can do
- Keys programming:For recording the code of the offered key.
- Pairing a replacement key:At the time of ordering an additional key or when programming a new key, so the waterscooter recognises it.
- A lost key deactivation:Remove the unit from memory so it can no longer start the engine.
- Working with both interface generations:The adapter is compatible with Jaltest Link V8.1 and V9.
Compatible vehicles and applications
Compatibility is determined by the connector type, not the model. This adapter is part of the 2-pin connector with yellow pin holder in the hull; the 3-pin diagnostic connection is that of the JDC601A. Do you have both fault finding as key programming on the software, you'll need both items. For waterscooters, there's never a standardised diagnostic connector prescribed, so these proprietary connectors remain in use on recent models as well.
Yamaha (disambiguation):
- 2-pin connection, yellow pin holder: Located in the hull of the waterscooter, separate from the diagnostic connector
- No year restrictions:For waterscooters, no standardised diagnostic connector has ever been mandated
- Reading data on the same watercraft:For that purpose, the JDC601A with the 3-pin connector is the product you need.
