OBD1 for Rover cars have first generation 'Onboard Diagnostics' systems.the OBD system allows mechanics to diagnose problems in the car.
The first step is to find your vehicles diagnostic plug.
The second step in troubleshooting the problem is retrieving the engine fault code. In this guide, we will take a look at how you can read and clear engine fault codes using various scanners.
The connector is usually located under your steering wheel, under the dash. The connector may have a black plastic cover over it and you may have to remove some covers to reach it. The connector is often black and has 12 pins on it, pretty easy to identify.
If your Check engine light is on you may have a serious problem. Scan your codes and follow the chart to determine what the code means.
You can get the codes for Rover cars yourself if the model of your vehicle is made before 1995, this means as soon as you see 'check engine light' in your dash, you can get the code in minutes if you want.When your check engine light is on or you're experiencing car problems, an appropriate OBD scan tool will let you talk to your car and help determine what the problem is.
When you turn the key on (do not start engine), the check engine light lamp in your dash panel will start to flash the codes. Codes are usually shown in 2 digits numbers like code 24 is 2 flashes, a pause and 4 flashes. A pause of 2.5 seconds will follow the next code. When all codes are transmitted, the entire code will be flashed again after 4.5 seconds.
