Auto Electrical Faults

Many malfunctions that occur in vehicles can be diagnosed as auto electrical problems. The source of these problems is usually related to the electricity that is being generated by the battery or alternator. Each of these car/4x4 problems can typically be separated into one of several categories.

Since the battery is the source of electricity for a vehicle, it is no surprise that it is commonly a cause for many automotive electrical problems. Usually the issue is a dead battery, caused when the battery can no longer hold a charge. Sometimes a faulty component of the vehicle can cause a dead battery. Other times it can be a result of leaving a component like the headlights or stereo on for an extended period of time. This problem can usually be remedied rather easily with either a jump-start or a battery recharge. A car/4x4 battery can also become damaged or simply too old and in need of a replacement.

Another source of a common automotive electrical problem is the vehicle's alternator. While an automobile is running, the alternator is recharging the battery. Once the alternator breaks, the battery is quickly drained and the vehicle loses power. Sometimes the alternator belt can also wear out or become cracked, leading to a similar malfunction where the battery easily becomes discharged.

Sometimes the source of an electrical problem in a vehicle can be a broken electrical wire or a blown fuse. All of the electrical components of a vehicle are attached to one another through the wires of the electrical system. There are also many vehicle fuses in this wiring, which protect sensitive automobile components from power surges. This is very convenient since it is much less costly to replace a fuse than an expensive auto part.

Some of the most important electrical components are the spark plugs and spark plug wires. When these go bad ,the engine will no longer properly work. This problem can usually be detected when the car runs rough in idle, accelerates poorly, stalls, or is getting bad fuel mileage. Bad spark plugs and wires can usually be remedied easily with a tune-up.

Another automotive electrical component that can cause car problems when it goes bad in a solenoid. These magnetic coils are used to distribute power to the starter and to provide the power to open automatic door locks. A bad solenoid can easily be confused with a bad starter or a dead battery, since any of these can cause the engine to not be able to turn over when starting the car.

All vehicles from 1980 on (except for some heavy trucks) have some sort of computer engine controls. The fuel/air mixture and often the ignition timing are electronically adjusted by a computer according to engine load, speed, temperature, even the altitude above sea level! The newer cars also use either the engine control computer (ECU, or Engine Control Unit) or a separate computer to shift the transmission. In the newest vehicles the throttle itself is controlled by the computer via an electric servo motor. There is no direct link to the throttle from the accelerator pedal. Modern vehicles use a computer, (or computers) and numerous computer sensors to control many aspects of a vehicle besides engine control. A bad computer sensor can cause many problems. A sensor error code can be misleading. Anti-lock Brakes and airbags are also controlled by their own separate computers. Computer problems can be hard to diagnose, Shift Automotive`s experienced team can diagnose & repair all cars 4x4 & light trucks auto electrical and auto computer problems and chip performance upgades.

Car Key Remote Programming

Nearly all replacement car key remotes require programming.  Most automotive remote transmitters do not work right out of the box.  Think about it . . . if they did, anyone could open your vehicle simply by buying a replacement keyfob.  There are only two situations when programming is not required:

1.  Some older fixed-code aftermarket alarm systems use remotes that are "hard-coded" to broadcast a unique signal that is matched to the receiver.  If this is the case for your system, Shift Automotive will ask you to provide us with a code number from inside the case of your original remote and we will pre-set the replacement remote to transmit that specific code.

2.  For some other old fixed code systems, replacement remotes are no longer manufactured.  If this is the case and you have an original remote that will still broadcast at least a weak signal, Shift Automotive Bundaberg will ask that you send us the working remote to copy.  The replacement remote will be an electronic "clone" of your original remote, so it will not require programming.

Apart from these two circumstances, any car remote you purchase will require programming.
