5.7 Layer 2 - identifier scan
In the operating mode "layer 2" (default setting), the CANcheck scans for message
identifiers transmitted via the CAN network. During the scan time (the default
setting is 10 s) the CANcheck generates a list of identifiers and counters that indi-
cate how often the identifiers were recorded.
If the identifiers in your CAN network are repeated with a period longer than
10 s, you must change the scan time. This is done via the menu item "Settings".
The CANcheck records both 11-bit-identifiers and 29-bit identifiers. The length of
the list with identifiers and counters is limited to the value given in section 10.1.
For the identifier scan, you can connect the CANcheck to the CAN network at any
point:
•
If there is a free SUB-D9 socket in the CAN network, you can connect the
CANcheck to this socket via the 1-to-1 cable.
•
If this is not the case, you can loop in the CANcheck between any CAN node
and the CAN network via the Y cable.
Please put the CAN network into operation before you start the identifier scan.
Please select the menu item "Identifier scan" with the keys UP and DOWN and
press the OK key.

During the measurement, first the baudrate is detected and the relevant message
appears. Then the scan for identifiers is carried out and a further message ap-
pears.
After the measurement the test result appears. Only the beginning of the list is
shown here. Scroll through the list with the keys UP and DOWN.
Error messages are explained in section 6.
