    You will need an OBD scan tool. The scanner allows you to communicate with the computer and retrieve the trouble codes. Certain scanners may give information on what the revealed code means, but most will just give a five digit number and letter combination. Follow these 4 steps to insert and read the OBD scanner:

    What is the manufacturer specific check engine light code?

    Manufacturer-specific codes use a number other than “0” as the second digit. In general, codes that begin with P0 are generic codes concerning a powertrain issue, whereas codes that begin with P1 are manufacturer-specific. Step 4: Determine which system the code applies to.

      What does the code on the Check Engine light mean?

      This onboard computer runs your car so that it has optimum fuel economy and low emissions. The PCM creates a code indicating what part or system is malfuntioning (electrical system, oxygen sensors, and so on). Your tech can get the code from the vehicle and look up its meaning.

      If you notice nothing strange, you can drive your car until you get it checked by an expert. When the check engine light is on, the ECU stores a code that resembles the vehicle’s fault. You can view this code via a diagnostic scanner.

      Before starting your car after it has sat idle for a long time, be sure to check your engine oil level. Check that your headlights, fog lights, high-beam lights, brake light s, reverse lights, and indicators are all working before you head out on the road.

      How do you check the oil level in a car?

      Check the oil level using your vehicle’s dipstick. If you’re not sure where the dipstick is located, refer to your owner’s manual for a diagram. The correct oil level should be between the two indicator marks on the dipstick. Be sure the engine is cooled off for at least ten minutes before you check the oil.

      When the ECU ( engine control unit) detects a problem that it is unable to regulate, it then turns on the check engine light on your dashboard. This check light will either keep on glowing or will blink, depending on the nature of the fault. If the engine check is on regularly then it means that there is a problem but not an emergency.
