So Fix it

You can access engine codes for your 1989 Volvo 240 from your home garage using an OBD I scanner. This hand-held computerized tool can be purchased from any auto parts store. The On-Board Diagnostics computer receives and stores error codes sent to it from the engine. Sensors in the engine detect malfunctions and servicing needs of the Volvo and send the error codes to the computer. The computer, in turn, illuminates the "Service Engine Soon" or "Check Engine" lights on your instrument panel. The codes can be read using an OBD I scanner. After you read the codes, this same tool can be used to reset the computer and turn off all warning lights after repairs or servicing has been accomplished.

Instructions

1

Plug the OBD I scanner into the large open port on the drivers side dashboard underneath the steering column.

2

Put the key into the ignition, and turn it to the "ACC" position, but dont crank the engine. Wait while the scanner turns on. Some scan tools have an on/off switch that needs to be turned on.

3

Select the "Read Codes" command from the scanners menu. Wait for the scanner to interface with the OBD computer. Write the engine codes it displays on a piece of paper.

4

Unplug the scanner.

You can clear the trouble codes on your Mazda MPV right from your home garage, saving yourself a trip to the mechanic or dealership. Mazda MPVs manufactured between 1989 and 1995 come equipped with an On-Board Diagnostics I computer (OBD I) and those manufactured from 1996 to the present have an OBD II computer. In either case, the procedure is the same, you just need a different tool to do the job. You must obtain a small, computerized OBD I or OBD II scanner. Clear the trouble codes after the vehicle has been serviced or repaired. Clearing the computer codes shuts off the warning and service lights on the instrument panel.

Instructions

The engine light codes, also known as diagnostic trouble codes, on a KIA Optima are designed to provide information about a specific failure or malfunction on the vehicle. These alpha-numeric codes are created by the engine control module and then stored in memory where they can be retrieved at a later date with a scan tool. These codes begin with the letter P and are followed by a four digit number sequence. Each code corresponds to a specific problem that can be identified by using a service repair manual. Most factory repair manuals provide a flow chart that technicians can use to diagnose and correct the problem that triggered the code.

Instructions

1

Turn the engine off, but rotate the ignition switch to the ON position. The dashboard must have power in order for the scan tool to communicate with the ECM.

2
