Fromme Road: Esnan Valles Rood fo Wellington Derive: Road con New technology makes accurate diagnosis routin We YOUR late model car begins running erratically, acting *tcrazy” and then, just as suddzniy, behav- ing normally, it may be suffering from an *tautomotive — neurotic disorder .** The new generation of vehicles have their own central nervous system of sensors and computers which communicate and interact within the various systems of the car. The result: a more efficient vehicle with lower exhaust emis- sions. This technology has placed greater demands on technicians who must diagnose and repair these vehicles. Accurate ‘'fault diagnosis’” often is required as a first step in the tune-up pro- cedure. Your new car will have dozens of sensors and microprocessors receiving information from fuel, ignition and cooling systems. In- stantancously they relay data to computers that calf for changes, as needed, in the vehicle's systems, A knock (or “ping’*) sensor, for example, which Hrerally listens for the sound of a spark knock, adjusts ignition timing to. elimi- nate the cause of the knock. Fuel/air mixtures will be changed electronically to compensate for driving in high altitude (where air is thinner). sor, monitoring those gases, takes corrective measures, Untortunately, these angoing compensations can camouflage a problem which continues to pro- geess until, often without warning, the malfunction no longer can be corrected. At that point the vehi- cle runs poorly, if at all, warns Car Care Canada of the Automotive Industries Association of Canada. Another type of computerized corrective measure is when poor engine performance affects transmission operation. This oc- curs when the roanifeid vacuum sensor tells the automatic transmission 10 stay in a lower gear longer or to downshift sooner to lighten the load on the ailing engine. fn such a situation, inaccurate diagnosis might suggest transmis- sion repairs to correct an odd shifting pattern when the real cure was a tune-up. Complicated as this may seund, accurate diagnosis is a rcutine procedure for the trained techni- cian working with state-of-the-art equipment. Car owners of the '90s may be less likely to understand whar's going on under the hoods of their vehicles, concludes Car Care Canada, but recognizing the im- portance of quality tune-up ser- Hunter St.-Mountein Hus. to Orwell St. Wicermiain fepdace- ment, becal trabtic only. fonn Salley Rd-Mountain Jivy. to Alun Rdus Sawecutuny pate: ment.
