Cds G3 Service Tool Home Screen Overview - Mercury MerCruiser Service Manual

Troubleshooting
Starting G3
With the G3 computer correctly connected to the vessel's CAN P bus and the G3 program running, turn the key to the on
position. The CAN P indicator should turn green, indicating that CAN traffic exists between the PCM and the computer.
The CAN indicators will let you know the communication status on CAN P and CAN H.
Green—The computer is communicating on the CAN bus.
Yellow—The computer is communicating with the cable but no data is being received on the CAN bus.
Red—The computer is not connected to the SmartCraft diagnostic interface cable.
If G3 Does Not Communicate with the Engine
If the G3 CAN P traffic indicator is green, the cable is communicating properly with the G3 program and the CAN bus it is
mapped to.
If the G3 CAN P traffic indicator is red or yellow, then there is a communication issue. Refer to the user manual loaded onto the
computer diagnostic system laptop (in the Windows® Start menu > All Programs > Mercury Marine > User Manual) or on the
G3 software installation disc.
