CAN COMMUNICATION SYSTEM
CAN SYSTEM OVERVIEW
The CAN system allows a large amount of information to
flow between components. The CAN system on this
vehicle will link the ECU, Diagnostic Connector,
Instrument Cluster/PIDD and EPS unit through a green
and a yellow wire.
CAN SYSTEM TESTING
A component not displaying information correctly could
be the cause of damaged CAN wiring or a faulty
component.
The easiest location to test the CAN system is at the
Diagnostic Connector.
Turn the key to the ON position. Using a multimeter, ohm
across the Green and Yellow wires at the diagnostic
connector.
• An ACE not equipped with a PIDD should see a
reading of 60 Ω. A reading of 120 Ω is bad.
• An ACE equipped with a PIDD should have a reading
of 120 Ω. Anything other than 120 Ω is bad.
