Identification of the PCU and the HCU

PCUs and HCUs in the EVC-C system have a label fitted on front side with the letter "C" printed on it and with the following marking: On the PCU unit PCU MID 187 On the HCU unit HCU MID 164 NOTE! New and old hardware are not interchangeable.

Label EVC-C version This is carried out by checking indentically designed labels, placed on the node gables, on top of the engine cover and on the engine control unit (ECU). Identification is done by using the ENGINE CHASSIS ID. number.

IMPORTANT! The CHASSIS ID. number on the node labels must correspond with the CHASSIS ID. number on the engine labels.

The CHASSIS ID. number is also intended for the Volvo Penta organisation for identification of the system in the VODIA diagnostic tool. The CHASSIS ID. number can also be shown in the tachometer display or in the EVC system display.

"Chassis conflict"

NOTE! If there is no correspondence between the CHASSIS ID. numbers, this will be indicated in the tachometer display or EVC system display. Alarm indication will also be shown in the displays and the fault indicator lamp in the alarm gauge will lit up with an orange light. (Alarm gauge is optional).

Each PCU and HCU (node) in the EVC system is programmed to communicate with a specific engine. Software can vary depending on engine type, equipment, parameter setting, etc. It is therefore, prior to installation, important to identify the different nodes.
