Satellite Communication System
Volvo Link ECU
The Volvo Link System provides satellite communications between a driver and fleet. It
includes the Volvo Link ECU, GPS antenna, cable, and wiring harnesses. Some vehi-
cles also include a dash switch. This system allows communications between Volvo's
Web based (fleet) software and the vehicle.
This information includes design and troubleshooting of the vehicle portion of the sys-
tem. For repair procedures, see service procedures in group 397. For fleet software
troubleshooting, see the software help file.

Page 3: Design And Function
The Volvo Link ECU is programmed differently for Cummins and Volvo engines. At the time of the original installation in the vehicle, the Volvo Link ECU acquires the Vehicle Identification Number (VIN) of the vehicle in which it is installed. Replacement of the ECU with one from another vehicle will not work. -

3.2002 7(32) Viewing Messages To view all stored messages, select “Volvo Link,” then “Read Messages” in the cluster’s graphic display. The messages will display, one at a time, with the most recent message shown first. Once the newest message is displayed, the driver can use the Up/Down buttons to scroll through the other messages. - Page 8 Page 8 Sending Messages from the Vehicle The driver of the vehicle can send messages from the vehicle to the fleet. Messages can be sent when the vehicle is stopped, but not while it is moving. If you attempt to send a message when the vehicle is moving, an error message will display, and the message will not be sent.
- Page 9 Wait briefly and try sending the message again. It may also be an indication that the Volvo Link ECU has been placed in the wrong vehicle (see “Cannot Send or Receive Messages, but No Fault Code” page 31 for more information).
