The pc on a vehicle has the capacity to store in-memory fluctuations of preset parameters for the system of all the items within its world of energy. Press the "Read" button on the code scanner. After a moment or two, the scanner will display a 4-digit code in the form of a number, for example, 1460. If there is more than one code, push the button for the next.
Instructions
1. Locate the OBD outlet under the dash, generally on the driver's side below the steering column.
2. Insert the cable end of the code reader into the OBD terminal outlet. Turn the ignition key to the on position with the engine off. These malfunctions that are stored in recognition can be accessed over the operate of a code reader. This can be purchased at most auto parts stores, and is quite inexpensive. The code reader comes with a code interpretation list useful in deciphering the codes. The computer communicates through the use of two-letter codes. Write all the codes down.
3. Use the code interpretation sheet provided with the scanner to cross-reference the numbered codes to the explanation for these codes.
4. Check any of the code-related items prior to condemning and replacing them. The computer sees a discrepancy in the operation or signal of the item that caused the service engine soon light to come on. Always check the wiring connector and the condition of the component first. In most cases, if there is no signal from a component, it is likely in need of replacement. There is one circumstance that requires much more diagnostics. If the code for an oxygen sensor comes on, it means that the computer saw a discrepancy in the fuel mixture. This does not necessarily mean that the sensor is bad. Anything from a bad plug wire, spark plug, mixture, vacuum leak and many other things can produce the same effect. Unless the code says (for example) "B1 S1 heater inoperative"--which is a true fault--the sensor is probably good.
5. After the repair is completed, turn the key on again with the engine off. Push the "Erase" button and the scanner will erase the codes and turn the light on the dash out until the next failure.
