hyundai-check-engine-light-flashing

(1) . check engine warning light

The check engine light is a yellow color warning light, when we turn the key on, this light appears in the dashboard meter along with other warning lights.

The check engine light appears in the dashboard in two ways, the first after turning on the key and the second when there is a problem with any sensor in the engine, then the check engine light appears at that time.

The check engine light is the light of the ecm and the ecm is connected with all the sensors in the car and does the work of receiving and sending signals.

Suppose if the mass air flow sensor in your car stops working after engine start, then at that time ecm stops getting signal from this sensor.

The ecm turns on the check engine light in the dashboard to transmit this information to us and we scan the car after seeing that light on and we come to know about the mass air flow sensor problem.

In this way the check engine light is on in the dashboard and the ecm controls this entire signal, but many times the check engine light itself disappears, we will tell about it below.

(2) . immobilizer light

The immobilizer light is called the security light, this light appears in the red color dashboard, the immobilizer light and the check engine light appear simultaneously when the key is turned on.

The immobilizer light is connected to the key of the car, during this you cannot use another key to start the car, if you do so, the immobilizer light starts blinking in the dashboard.

Immobilizer light is used to protect the car from theft, it is connected with system immobilizer, ecm, cluster meter, key

Suppose the code of your car key is 0007, then the same code will also be of immobilizer, ecm, cluster meter and as soon as you turn on the key to start the car, the 0007 code will match and the car will start.

But if you put the key of 0005 code in the car of 0007 code, then the immobilizer light will start blinking, thus the immobilizer system works.

hyundai check engine light flashing problem

check engine light flashing problem is a problem related to ecm, when there is a problem related to ecm in the car or there is a problem in the wire of ecm, then there is a problem of check engine light flashing.

We just got a Hyundai car some time ago, the car owner said that as soon as the key is turned on, the check engine light and immobilizer light blink.

and the car does not start sometimes both these warning lights stop the owner of the car got the car scanned but no fault code shows up

After that when we checked the car, we found that there was a problem in the ecm of that car, the ecm of that car was damaged, due to which the check engine light flashing problem was happening.

We got the car’s ecm, immobilizer and key checked, corrected the system, after that when the ecm was installed, the immobilizer light and check engine light stopped blinking.

And the car started as soon as the self was installed, but keep one thing in mind, if only the check engine light is blinking, then there is a very bad effect in the engine.

For example, if the mixture of fuel and air in the engine is not correct, the fuel is less and the air is going too much, at that time due to not burning the fuel properly, there is more misfiring in the cylinder.

Due to which the engine starts shaking, there is a lot of vibration in the car, to indicate misfiring in the cylinder, the ecm flashes the check engine light in the dashboard, when this happens, stop the car.

Or there is a 90% chance that the ecm is bad in the problem of the check engine light flashing, but at the same place if the check engine light is fine and the immobilizer light is blinking, then there can be many different reasons for this.
