Service manual

CANDoo Professional
256
NOTE: Before connecting to a ski, please read the service manual for the particular
model of Waverunner!
In general, starting a diagnostic session involves two steps:
1. Connecting the Candoopro system to the Waverunner diagnostic connector
“ Waking up” the engine ECU to enable the Candoopro system to talk to the ECU
2.
Connecting the Diagnostic Cable to the Waverunner:
Some Yamaha engines (like the outboard motors) have a dedicated 3-pin diagnostic
connector , butWaverunners do not have a dedicated diagnostic connector. The
gauges/clusters onWaverunners “ speak” to the ECU in the same way that their
diagnostics tools communicate with the ECU, so YamahaWaverunners have a standard 3-
pin connector in the front storage area that is used to communicate information to the
cluster during normal ski operation, and is used for the diagnostic tool (Candoopro
diagnostic system) for a diagnostic session.
Steps to connect:
1. Locate the 3-pin cluster/diagnostic connector in the front storage
compartment of the ski. You may need to open an access panel on some
models to get to the connector. The connector is a three-pin dark gray
connector:
