3. You are now ready to “wake up” the ECU and start a diagnostic session.
Waking up the ECU:
In order to initiate a diagnostic session, you need to “ wake up” or turn on the ECU. This
is done by starting the ski. ( or attempting to start the ski if it will not run!)
1. Start the Waverunner engine. If you wish to do an active diagnostic session
while the engine is running (for example, using the engine monitor function,
or to drop a cylinder while running) please follow the instructions and
warnings in the service manual for this vehicle, and make sure you supply
cooling water to the engine per the service manual.
2. If you do not wish to run the engine while doing diagnostics (for example, to
read and clear faults) you can just start the ski, start the diagnostic session
with Candoopro, and shut off the engine. Once the ski is in diagnostic
mode, the ECU should continue to stay active. (if it should happened to
shut down, just restart the ski and start the diagnostic session over)
Starting the Diagnostic Session:
When the Candoopro application is running, and the ECU has been woken up, you are
ready to start the diagnostic session.
