• Scania has become the latest truck manufacturer to introduce a workshop diagnostic computer for its dealers.
The system comprises of a portable computer which is connected into the diagnostic socket that have been a standard fitment on new vehicles over the past year.
Once connected the vehicle's chassis number is entered; this automatically selects all the correct options. The technician then selects which electronic system the computer is to diagnose.
Any stored fault codes are displayed and information is given on the fault finding procedure. The next generation, with step-by-step fault finding, is already under development using the same base hardware.
Initially 12 dealers will get the computerised system, which can interrogate ABS/ASR, CAG and EDC speed limiters.
Wiring diagrams, including all connection and threedimensional views of the vehicle, can be called up to trace circuits and locate components.
Individual solenoids, valves and wheel sensors can be operated by the computer to check their operation.
The computers remain the property of the manufacturer and are programmed with each dealer's code number which is automatically logged into systems like the speed limiter when changes are made.
Scania has computerised its contract maintenance quotation system. After feeding in details of vehicle age, specification and use, the computer calculates monthly maintenance costs for 12, 24 and 36 months.
