Summarized tests
If you erroneously start the test when the CAN network is switched on, you will
receive the following error message, because tests of the line parameters are not
possible when the CAN network is switched on.
Line parameters
Voltage detected
on CAN bus
Test rejected
Then you return to the system menu with the ESC key. There you can start the
next test with the CAN network switched off. Now you receive the test instruc-
tions.
Wiring test
-Disconnect all nodes
-Terminate CAN bus
on both ends
OK Start test
The header shows that the wiring is tested first. The test instructions are to be
understood as follows: generally for tests of the line parameters, all CAN nodes
should be disconnected from the CAN network. Switched off CAN nodes that
have a high resistance between CAN_H, CAN_L and ground may remain con-
nected. As the resistors of all connected CAN nodes are parallel, however, the
resistance of every individual CAN node must then be greater than the "number
of CAN nodes" x 1 k
Ω
.
If this condition is met, press the OK key.
During the measurement a message appears.
