Electrical Systems Operation & Diagnosis Module (602)
Low Speed CAN
Low Speed CAN (ARTWORK)
When the logic value of the Low Speed CAN is 1 the voltage of the CAN High signal is 0 volts
and the value of the CAN Low signal is 5 volts. As the logic changes to 0 the CAN High voltage
will change to 4 volts and the CAN Low signal will change to 1 volt.
The terminators of the Low Speed CAN only operate while the circuit is active. This prevents
checking of the total circuit resistance of the Low Speed CAN. If a trouble code of the Low Speed
CAN is present, check the voltage at the Low Speed CAN high and low wires for voltage or
oscilloscope patterns. Resistance checks can also be performed when no voltage is in the circuit.
