Here is a step-by-step guide to solving the blinking \u201cD\u201d light problem for all the possible causes:<\/p>\n\n\n\n
#1.\u00a0Check the Transmission Fluid Level<\/h3>\n\n\n\n
- \n
- Please ensure that the car is parked on a level surface and that the engine is running.Shift the transmission briefly through each of its gear settings before putting it in the park.<\/li>\n\n\n\n
- Then, raise the hood and locate the automatic transmission fluid dipstick, which is typically near where the transmission or transaxle meets the rear of the engine. This appears to resemble the oil dipstick.<\/li>\n\n\n\n
- Remove the automatic transmission fluid dipstick, wipe it clean with a clean rag or paper towel, reinsert it fully, and remove it again.<\/li>\n\n\n\n
- Observe the markings at the end of the dipstick. Your dipstick may include two different “full” markings – one for when the engine is warm and another for when it is cold.<\/li>\n\n\n\n
- If the automatic transmission fluid level does not come up to the \u201cwarm\u201d line, you will need to add automatic transmission fluid.<\/strong><\/li>\n<\/ul>\n\n\n\n
2.\u00a0Add Transmission Fluid If Necessary<\/h3>\n\n\n\n
If you find that your transmission fluid level is low, you can add more until it reaches the appropriate mark. It is important to use the appropriate transmission fluid for your car to ensure proper functioning.<\/p>\n\n\n\n
3.\u00a0Check for Error Codes<\/h3>\n\n\n\n
If you have a drive light blinking problem, you can get an OBDII scanner and get the codes to know the cause of the blinking.<\/p>\n\n\n\n
For example, if your \u201cD\u201d light is blinking because of the transmission problem, it will show the P0847 code.<\/strong><\/p>\n\n\n\n
On the other hand, if the \u201cD\u201d light is blinking because of a faulty alternator, it will show the P0562 code.<\/strong><\/p>\n\n\n\n

<\/figure>\n\n\n\n4.\u00a0Check the Alternator<\/h3>\n\n\n\n
The blinking \u201cD\u201d light indicates a faulty alternator. Therefore, first, check the alternator of your car. To check the alternator, perform the following steps:<\/p>\n\n\n\n
>> Perform a Headlight Test<\/strong><\/p>\n\n\n\n
- \n
- Start your car and turn on your headlights.<\/li>\n\n\n\n
- Press the accelerator with the vehicle in park while a second person observes the headlights.<\/li>\n\n\n\n
- If you press down on the accelerator and the headlights flicker, dim, or get brighter, it is possible that the alternator in the car is malfunctioning.<\/strong><\/li>\n\n\n\n
- If there is no change in the brightness of your headlights, it is probable that your alternator is fine.<\/li>\n<\/ul>\n\n\n\n
>> Check for Error Code<\/strong><\/p>\n\n\n\n
Connect a code reader to the diagnostic port to find out if the cause of the blinking \u201cD\u201d light is a faulty alternator or not.<\/p>\n\n\n\n
5.\u00a0<\/strong>Check the Charging System<\/strong><\/h3>\n\n\n\n
If your alternator is not performing properly or not producing enough power, a simple charging system test will be able to identify it. This standard inspection is performed at auto dealerships and repair businesses regularly.<\/p>\n\n\n\n
If you have a Charging System Analyzer, testing the alternator and the charging system is quick and easy.<\/p>\n\n\n
