CONTROLLER AREA NETWORK (CAN)
This vehicle uses a Controller Area Network (CAN) to perform some functions. Similar to a computer network, CAN
establishes a communication network between the ECM and several on-board components.
The CAN network includes:
• ECM
• Instrument Cluster
• Digital Wrench Diagnostic Plug
• Electronic Power Steering (EPS models only)
NOTE: DO NOT SPLICE OR CUT INTO THE CAN YELLOW OR GREEN WIRE CIRCUITS.
CAN Troubleshooting
No CAN functionality can be indicated by the following items not working on the instrument cluster:
• No engine speed displayed
• No vehicle speed displayed
• No gear position displayed
• Odometer / Tripmeters not working
• Reverse override button does not toggle between display modes
• ECM-monitored inputs are not displayed when DTCs or problems exist, i.e. check engine LED, engine overheat
LED, etc.
• There is power at the Smart Link connector, but it cannot connect to Digital Wrench
To test the CAN circuit, turn the ignition key to OFF, and then use a multimeter to verify there is 60 +/- 10 ohms
between the CAN High (YELLOW) and CAN Low (GREEN) wires on the diagnostic connector.
If 120 ohms is measured at the connector, there is a break somewhere within the CAN circuit.
