EOBD II Error Code: P0600

Fault Location:
Serial Communication Link - Malfunction/Message Missing

Possible Cause:
Malfunction Indicator Lamp (MIL)(K83) Non Emission Fault - No warning light.

Wiring/Connector(s).
Connected system.
Trouble code(s) stored in other system.
Low battery voltage.
Engine Control Module (ECM).

Possible Solution:
Check Can-Bus matching resistor.
Check and charge battery.

Description:
The Engine Control Module (ECM) communicates with all Data Bus-capable control modules via a CAN Data Bus.
These Data Bus-capable control modules are connected via two Data Bus wires which are twisted together (CAN_High and CAN_Low), and exchange information (messages). Missing information on the Data Bus is recognized as a malfunction and stored.
Trouble-free operation of the CAN-Bus requires that it have a terminal resistance. This central terminal resistor is located in the Engine Control Module (ECM).
