False Alarms! - Then Red Mirror Light flashs 7 times-Help!

[Stewart Smith]

I knew everything was going too well. Haven't been on for a while cos it's been working fine.

But - my 1996 C200 alarm has started goin off intermittently.

When I turn the ignition on afterwards, the red light on the rear view mirror flashes 7 times, pauses, then flashes 7 times again.

- Is this a code to tell me what circuit is alarming?

Its one of the alarms with the sensors on the a-pillars

Thanks

Stewart.
