Ignition misfires are insidious because they often occur only sporadically. With the ignition coil deactivation of the M-JET DIAGNOSTIC, you can pinpoint such problems to a single cylinder.
What ignition coil deactivation does
This function selectively deactivates the ignition of a cylinder. By observing the engine's reaction, you can determine if the affected ignition coil and its cylinder are working normally.
Ignition coil or injector?
In combination with injector deactivation, you can clearly separate two causes: If the engine reacts when the injection is switched off, but not when the ignition is switched off, the suspicion is more on the ignition side, and vice versa. This way, you systematically narrow down the component.
How to proceed
- Let the engine run at idle
- In the service area, switch off the ignition of a cylinder
- Observe RPM and running behavior
- Compare with the other cylinders
For diagnostic purposes only
Ignition coil deactivation is intended exclusively for troubleshooting and should always only be performed for a short time. Ensure stable board voltage, for Sea-Doo vehicles, for example, with the M-JET CTEK charging adapter.
For the entire Rotax family
Whether Sea-Doo, Ski-Doo, Lynx or a jet boat with a BRP Rotax engine: The function works on the same principle everywhere.
Conclusion
With ignition coil deactivation in the M-JET DIAGNOSTIC, you can find even hard-to-pinpoint ignition problems, precisely and without expensive guesswork.
