2004 Honda Accord: SRS light comes on when opening a door
 

When I open the door, the SRS light sometimes (but not always) comes on. Since this may mean that the air bag has been deactivated, I have to turn off the engine and restart the car before I can go. This often happens when I have to get out of the car to open or close the garage door. Has this ever happened to any of you? Why would opening a door trigger the SRS light? Is there something in the door that is somehow connected to the SRS indicator light?
