Check for crash sensor on the driver-side fender, is it loose? if so with key off tighten it the crash sensor is made of a metal ring that is magnetized and has a metal ball in it when you hit something on the side the steel ball leaves the unarmed position to the armed position, called an accelerometer this is one of three things that has to be met before arming air bag, so check the connection and tightness, if you can't see a visible problem I can give yo a site to go to that can help you diagnose this for $20.00, but is to dangerous for me to put here in open forum so it is best you talk to air bag experts. If you want it just post it here. Remember it could cause unexpected air bag deployment.

the indicator lights flashing constantly might be a warning from the car that all the doors have not been closed properly
after writing this ^^ i think that the system that tells the car if the door is open or closed it damaged or broken
and needs replacing
try leaving all the doors open and lock the car do the indicator lights flash contantly?
you need to get a dianostics done but due to the reson that it is intermmitant the problem will not exist when you get to the garage
check all the sensors that tell the car if the door is open firstly

It's an 02 sensor (oxygen sensor) fault. One if your 02 sensors is bad and/or catalytic converter is bad.
