When measuring resistance value or voltage in CAN bus lines, use a digital multimeter. If not using a digital multimeter, the equipments, which are connected through the CAN communication lines, may be damaged. |
|
CAUTION:
When measuring the resistance, disconnect the negative battery terminal.
|
Disconnect the negative battery terminal when measuring the resistance value in the CAN bus line. If you fail to do so, the equipments, which are connected through the CAN communication lines, may be damaged. |
|
CAUTION:
The test wiring harness should be used.
|
Always use the test harness when measuring the voltage or resistance value at the female connector. If you fail to do so, connectors may be damaged. |
