As we know, all cars sold In USA after 1996 should be OBD 2-compliant. OBD stands for On-Board Diagnostic; these cars all have a data link connector supplying a way to access the on-board diagnostic computer system.
As we know, all cars sold In USA after 1996 should be OBD 2-compliant. OBD stands for On-Board Diagnostic; these cars all have a data link connector supplying a way to access the on-board diagnostic computer system. The car's computer offers valuable diagnostic information regarding a lot of problems the car might experience. Any time the computer detects a trouble, it records all of the sensor readings at the time of detection. This data supplies useful information for evaluating the car's performance.
You'll Need OBD2 compatible car, OBDII to USB cable, OBD2 software and Laptop computer for this job.
Locate the OBD2 data link connector (DLC). In general, the DLC is under the dash of the driver's side of the car. The connector will have a minimum of 16 pins, while some manufacturers' DLC ports have more than 16 pins.
Get a cable that connects from an OBD 2 DLC to a computer. A few different manufacturers make cables for this purpose. Make sure that the computer side of the connector allows linking to a USB port.
Insert in the cable into the DLC. Use the first 16 pins open on the data link connector.
Install software to read the car computer. There are a few different programs that read OBD 2 compliant computers. Some OBD 2 software is available for free, such as Scan Master ELM and OBD Gauge. There are also more complete commercial OBD 2 software titles available for purchase.
Insert the other end of the cable into your computer's USB port. Since the computer will need to connect to the data link connector, a laptop computer is commended.
Run the software to read the car computer. Each OBD 2 software title is slightly different about how to run the process of reading the car's OBD computer. Look up the software manual before getting started. There are a lot of online stores over the internet; you can find that what you need online.
Tips to Check the Engine OBD Code without a Code Reader on a Dodge Stratus
Car manufacturers in USA started to equip their cars with the OBD system in the early 1980s. In 1996, when the system was made mandatory, most manufacturers changed to the second generation system, the OBD 2. Trouble codes stored in the computer of the first generation OBD system may be accessed through different methods, relying on the special make and model.Instruction of Replacing a Neon MAP Sensor with OBD 2 scanner
Manifold absolute pressure (which short for MAP) sensor of car is located on the front portion of the Neon's air intake manifold and has two small screws securing it into place. MAP sensors are responsible for identifying the air pressure within the manifold and sending a reading to the engine's ECU (engine control unit) referring to the voltage level for the spark in the ignition cylinder.Instruction Retrieving Car Trouble Codes without OBD tool
Manufactured before 1995 model of car typically come with the OBD 1 trouble-code system; cars made after 1995 generally come with the OBD 2 system. The differences between the two systems are that the older codes system contains only two digits, while the new codes system start with a letter showing what system in the engine is fault, followed by a series of numbers.
