Checking for a short-circuit in the CAN bus system, low speed network
Checking for a short-circuit
Disconnect the upper electronic module from the bus cable (disconnect the connector from the control module).
Note! Take care that you measure directly at the connector so that it is not damaged.
If the resistance is 0 ohms between the terminals, there short-circuit somewhere in the bus system.
To connect the breakout box to the upper electronic module, see Connecting the breakout box See: Body and Frame/Body Control
For further information about the connectors and bus cable, see the wiring diagram.
