Hi Ive seen that there is a led light that shows the BECM wakes up but where is it on a manual please. Ive looked but cant find it. I bet it right under my nose.

Could be wrong (nothing new there !) but think its only on autos, mines manual and only light I have is the one on top of the dash.

Autos Only....

Top of Dash Lamp is the Alarm visual indicator/deterant lamp

For the manuals you will have to hook up the ammeter to the battery and do it the old fashioned way to test the BeCM waking up and sleeping. Besides which will you a more accurate picture

Thanks for all your help.
I'll do it with a mutimeter then to make sure it go asleep. unless i can put it on the BECM it self.

just remember it needs 2 - 4 minutes to fall asleep. should then draw about 0.03A if i recall correctly. and remember the problem isn't so much about whether it will go to sleep as it is about how often does it get woken up.

I have timed the BECM on my 2000 DSE auto.
It takes exactly 2 mins to go asleep. I found having the bonnet open doesn't effect the time either. Starts off at 0.63A then drops to less than 10 mA.

Having the bonnet up didn't make a difference? Now there's a surprise.

dave4x4 · Dec 1, 2012

No difference. I just locked the car on the fob and it took exactly 2 mins to go asleep with the bonnet both open and also closed. Of course the alarm beeped with it open.
I made a plug to activate the bonnet switch to the closed position when it was actually open so I could measure the current easily.

And when I was looking for current drain I put the car battery under the car using my jump leads to connect it to the car!

Wasted effort, it seems!

Well, I'll know for the future.

Cheers,
