FIAT BRAVA BRAVO 1 6 This month I am going to take a slightly different look at a profitable vehicle within the Fiat range They appear in the following variants 1 4 BOCSH MA 1 7 3 1 6 IAW MPI 1AF 1 8 HITATCHI MPI 2 0 BOCSH M 2 10 4 It is worth noting that ALFA use very similar systems in their 2 0 vehicle range Two key problems pardon the pun are immobiliser errors using encryption key systems and injector failure I have chosen the 1 6 for the purpose of evaluation The system is fully supported by serial communication from a number of manufactures with access to serial data and Dtc s The ECM is easily located by the side of the battery 55 pin Bocsh pattern socket is supported by breakout boxes from both Sykes Pickavant and Autodiagnos Ignition system is wasted spark type and is easily accessible at the rear of the cylinder head Coil failure is common on Fiat vehicles do check their output and insulation carefully I could say a lot about the injectors most of it unprintable but they do earn good profit Ranging from total failure resulting in a misfire to subtle 
FREEHAND SKETCHING Sketching is a very important technique for technical communication. Sketches can transfer ideas, instructions and information in a clear, concise form. “Thinking with a pencil” is a practice designers use to bring ideas and mental pictures to reality. Freehand sketches are often the first view of new designs. Long before formal drawings are made or computer models are created, a series of detailed sketches are analyzed and approved. Sketching is a personal skill which everyone can improve.
