CAN-bus, checking<br />

Function<br />

The Motronic Engine Control Module (ECM)<br />

-J220- communicates with other CAN-bus<br />

compatible control modules via a CAN-bus.<br />

These CAN-bus-capable components are<br />

connected by a pair of twisted CAN-bus<br />

wires (CAN high and CAN low) and<br />

exchange information (messages).<br />

Information missing from the CAN-bus is<br />

recognized as an error and stored.<br />

The CAN-bus requires a matching resistor<br />

to function fault free. This matching resistor<br />

is located in the Motronic Engine Control<br />

Module (ECM) -J220-.<br />
