Honda CRV alarm for headlights stopped working

I have a 2002 CRV. The headlight alarm worked when we purchased the vehicle. It has since stopped. Is there a fuse that needs to be replaced?

Another unwanted recently new feature is sometimes after I unlock the car and open and shut the doors, they lock automatically. Could this be related to the headlight alarm issue?

Re: Honda CRV alarm for headlights stopped working

Check the plunger switch for the drivers door, oval shaped with black rubber cover (easily seen with drivers door open) See if it is broken and check it's operation. One phillips screw and 1 connector to remove, can be swapped with passenger side switch.

Are you missing your dome lamp when drivers door opens ??

Re: Honda CRV alarm for headlights stopped working

I checked the plunger swith inside of the door frame. That seems to be operating.

The dome lamp also works when opening the doors.

Any other ideas?

Re: Honda CRV alarm for headlights stopped working

If your dome lamp is working when the drivers door is open the switch is working.

How about "key in ignition" warning is it working o.k. ??

Re: Honda CRV alarm for headlights stopped working

The "key in ignition" warning I'm not sure about. I do get a dinging sound when the key if first put into the ignition. But no warning after that, once I turn the car off and leave the key in the ignition and/or open the car door, there is no warning. I'm not sure if it ever did this.

Could it be a fuse or something more electrical?

I bought the car used. It didn't come with an owner's manual.

Re: Honda CRV alarm for headlights stopped working

If the drivers door is open you should get beeping the second you insert the key.

The element making the noise is the same for both the "key in,drivers door open" and the "headlights on" warning.

Make sure the dome lamp comes on with the driver doors opening and also that the "key in" warning is working with the driver door open as well.

This will help eliminate piezo element and door switch as defective.

Yes, the dome light goes on when the door is opened.

After I put the key in the ignition the "key in" warning beeps 6 times. That's it. It doesn't beep again when the door is opened if the key is left in.

Re: Honda CRV alarm for headlights stopped working

6 beeps is what you get when the seatbelt is not fastened and the key is turned to II.

You should be getting beeps starting the second you insert the key (with drivers door open) it would continue until key removed or drivers door shut.

Has any work been done recently ? (electrical or mechanical)

You mentioned the doors re-locking, That would normally occur if you unlocked the car and did not open any doors for 30 seconds or so. It appears the system is not seeing that your drivers door has been opened (except for the dome lamp works)

Re: Honda CRV alarm for headlights stopped working

I haven't had any electrical or mechanical work done on it.

Sounds like I need to take it in? It's not a matter of replacing a fuse or something else that would be simple to fix?

Re: Honda CRV alarm for headlights stopped working

I would say if it was a blown fuse or similar you would have other symptoms (other systems not working)

Re: Honda CRV alarm for headlights stopped working

I have the 2003 Honda CRV. My car does not warn me if my headlights are left on when I open the door. To be honest, I do not remember it ever doing that. I have run my battery down so many times I have lost count. I checked and when I open the door and insert the key I do not get and beeps. What could the problem be?

Is your dome light coming on when the drivers door is open ??

The line (ground) for the drivers door switch feeds into the "multiplex unit" If the dome light is coming on, then the signal is making it to the control unit. The 01-02 Civics have had some failures of the mpx control units.

Re: Honda CRV alarm for headlights stopped working

I still have this problem with my 2002 CRV. I too have run the battery down for leaving on the lights without the warning sound.

The dome light does come on so it's not the ground line.

I was told it could be a broken spring. The name of the part escapes me. There is a little button (spring) covered by a piece of rubber inside the door frame. Possibly it sends the alarm if the lights are on and the door is opened? Apparently this can be replaced. You need to take the rubber cover off and unscrew the spring. I still need to look into this.

Please let us know if you find a resolution.

TIA
Kristi

Re: Honda CRV alarm for headlights stopped working

The button is called the "Plunger switch" See the second post of this thread.

Re: Honda CRV alarm for headlights stopped working

I also see it's not the plunger switch if the dome light works when the door is opened.
