I own a Mazda 3 manufactured 2009.

Recently the door light on the dash remained on for a few seconds after the engine was switched off and doors closed. Normally the light would turn off as the last door is closed.

The dealers in T&T ran a diagnostics test today (5 Oct 10) which was inconclusive.

It showed that the cranking amps was below the recommended level and suggested a battery change. However, they cannot say whether or not the problem would be rectified.

Has anyone had a similar experience?
What steps were taken to correct it?

 

so what was the order of actions to get this... sounds like you're stating two scenarios
1. doors closed & turn off the engine.
2. the engine is off and you close the last door.
