it makes the indicators(the turning lights) blink on and off.
It's your seat belt indicator light. Look at it when you first start your car when the light goes off so does the buzzing noise.
it has to be a relay or ignition problem
To reset the service indicator. Switch off the ignition. Push and hold the mileage reset button (on the right) switch on the ignition (whilst still holding the button) the display will count down from 10 to 0 when it reaches 0 let go switch off the ignition and switch on the indicator should now be reset.
With the ignition off, hold the trip meter (the '000.0' button) in. Turn the ignition into the electric position. You will see a countdown go from 10 down to 0. When the counter hits zero, release the button. You then get a ==0== message. Now turn the engine on. That's it.
your flasher relay is malfunctioning.
Bad relay
Are the keys in the ignition? If so all you have to do is take them out when you open the door.
There is a relay switch in the circuit which switches the light on & off when you activate the turn signal.
I have a 2004 Odyssey. Here's what the manual has to say about the green key indicator on the instrument panel: "Immobilizer System Indicator. This indicator comes on when you turn the ignition switch to ON. It will then go off if you have inserted a properly-coded ignition key. If it is not a properly-coded key, the indicator will blink and the engine will not start. This indicator also blinks several times when you turn the ignition switch from ON to ACCESSORY or LOCK." Hope this helps!
First, turn on ignition and hold down right trip button while turning off ignition. Then, turn ignition back on and release right trip button. And then, turn left trip button to the right and release. Finally, turn off ignition. Service indicator should be reset when you next start the vehicle.
Fuel pump relay is stuck. Replace it.
