Connecting a scan tool to a 2001 Kawasaki 1100 STX DI personal watercraft (PWC) can simplify the diagnostic process. While a specialized software and cable exist, they can be expensive and difficult to use. A more practical option is the Candoo Pro, a Kawasaki-specific code scanner available for purchase or through a local technician. Using a professional service might cost between 0-1 hour of labor. Alternatively, buying the scanner, using it, and reselling it at a slight discount is a viable option.
Diagnosing Potential Issues
A common issue in the 1100 STX DI is the crankshaft position sensor. Having a spare on hand is recommended due to its sensitivity and potential difficulty to find a replacement. The stator should also be checked against factory specifications. However, be aware that previous repairs on the Engine Management Module (EMM) might have been performed improperly, potentially leading to further complications. Kawasaki’s EMM is sensitive and can be damaged if the battery is connected with the ignition on. Replacement costs around $500, making thorough diagnostics crucial.
The fuel pump is another potential culprit. Exercise extreme caution when working around the ignition system due to the risk of electric shock. Remember that only the recommended spark plugs should be used in this PWC; no substitutes are permitted.
Essential Diagnostic Steps
Before connecting a scan tool, perform some preliminary checks:
- Fuel Pressure: Verify fuel pressure meets specifications.
- Spark Plugs: Ensure the correct spark plugs are installed.
- Stator Ohm Test: Measure the stator’s resistance to identify potential winding issues.
- Stator AC Voltage Test: Measure the AC voltage output of the stator.
- Battery Voltage Test: Confirm the battery is providing adequate voltage.
Utilizing the Candoo Pro
The Candoo Pro significantly streamlines the remaining diagnostic steps. After completing the preliminary checks, using the Candoo Pro can pinpoint the fault codes and guide further troubleshooting. This targeted approach avoids unnecessary part replacement and saves time and money.
EMM Repair Considerations
If the diagnosis points to a faulty EMM, consider contacting a specialized repair service like Lakeside. Be aware that if previous repairs were performed incorrectly, the EMM replacement process might be more complex and costly due to injector matching requirements. These controllers are difficult to replace due to the injector matching requirements. Improper prior service can significantly impact the repair process.
