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).
Measure the resistance at the connector between terminals #3 and #5. The resistance must be 120 ohms.
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.
