OBD II Connector
Note: ISO9141-2 & ISO 14230
(keyword 2000) use the
same pinout, so you cannot
distinguish between the two by
simply examining the connector.
Connect and use the CTB.
Monitor the LED indicators for
protocols activity to identify the
network structure in use.
CTB and CAN-Bus system diagnostics
Please note: Some vehicles may require connection of a scan tool prior to connecting
the CAN Test Box. This is necessary as a scan tool may be needed to log on as a
communication node of the CAN-Bus system. Without scan tool recognition, the
system will not transmit signal data to the CTB and therefore connection of the
CTB may result in failure of the CTB interface LEDs to operate when performing a
diagnosis.
