CAN Continuity Tests
If a communication problem is present, perform
the appropriate continuity test relating to the com-
ponent reported by B.U.D.S.
Test wire continuity between the corresponding
terminal of the CAN bus bar in fuse box no. 2 and
the suspected component as follows.
Remove cover from fuse box no. 2.

FUSE BOX #2
1. CAN LO bus bar
2. CAN HI bus bar
Inspect bus bar condition.
Disconnect the connector from the component to
be tested. Refer to its appropriate subsection.
Use the
FLUKE 115 MULTIMETER (P/N 529 035 868)
and select .
Refer to the CAN BUS DIAGRAM above and read
wire resistance between the proper bus bar termi-
nal and the component terminal. Check the con-
tinuity of the WHITE/RED wire and the continuity
of the WHITE/BLACK wire.
The following gives an example between the CAN
LO wire and the ECM.
NOTE: When working with the ECM, install the
ECM ADAPTER TOOL (P/N 529 036 166)
on ECM "B"
connector.

EXAMPLE CHECKING ECM CAN LO WIRE
If continuity is good, CAN lines are functional.
If continuity is not good, check wiring, connectors
and terminals condition.
NOTE: It may be necessary to check the continu-
ity to more than one component.
Reconnect connectors and reinstall removed
parts.
