Identification of the PCU, HCU and SUS

Each PCU, HCU and SUS in the EVC system is programmed to communicate with a specific engine. Software can vary depending on engine type, equipment, parameter setting, etc. Prior to installationIt is therefore important to identify the different nodes. This is carried out by checking indentically designed labels, placed on the node gables, on top of the engine cover, on the engine control unit (ECU) and on the Servo Unit Steering (SUS).

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 engine and SUS labels.

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.

The CHASSIS ID. number on the node labels are also intended for the Volvo Penta organisation for identification of the system in the VODIA diagnostic tool.

The CHASSIS ID. can also be shown in the tachometer and 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. Alarm indication will also be shown in the EVC system display and the fault indicator lamp in the alarm gauge will lit up with an orange light. (Alarm gauge is optional.)

Gears cannot be engaged.
