Electrical System

Possibilities with New Technology The use of new technology in the electronic system for the A25D and A30D gives great possibilities to increase the vehicle’s level of intelligence. The machine can be adapted to the user’s wishes using the Software Options , and the operator can receive con- tinuous information about machine status. The improved diagnostic possibility means easier, faster and safer trou- bleshooting VCADS Pro Beginning with the articulated hauler D-series, Volvo CE will start to use the Volvo common aftermarket tool VCADS Pro. VCADS Pro is an abbreviation of Volvo Computer Aided Diagnostic System Professional. Volvo Truck has been using VCADS since 1993. VCADS Pro is used by Volvo Trucks, Volvo Bus and, also within Volvo CE. VCADS Pro is a tool for the service mechanic. It consists of a heavy-duty, rugged portable computer with VCADS Pro software. Main features VCADS Pro has two main features, software program- ming and test/diagnosis. - The software programming module is used to upgrade/ replace the software in the machine’s electronic control units (ECUs). - The test module consists of several separate tests that the mechanic can use when troubleshooting the machine. An example of a test is the cylinder compres- sion test. When performing a cylinder compression test, VCADS Pro interacts with the Engine ECU. It takes about five minutes to perform his operation. A traditional compression test on a D10B engine takes approximately seven hours. This is a good example of how we can use the machine’s increasing level of intelligence to reduce service downtime. Service and programming socket The Contronic service socket and PC service socket are connected to the information bus and are used for com- municating with external equipment. VCADS Pro, the PC-tool used for: • Programming control units • Downloading vehicle parameters • Reading error codes • Testing and checking functions/components Contronic service display unit is used for: • Reading error codes • Setting certain customer parameters • Showing machine information/status of engine, trans- mission, dropbox and hydraulics • Showing software (program) version in control unit • Showing status of inputs and outputs on control units
