Nissan Micra 1.0 2004 - Battery drain #

Posted by Craig Shiraz on February 4, 2013, 12:39 pm

Year of Manufacture *: 2004
Engine Size and Code *: 1.0 K12

Hi guys

We are having battery drain issues on this vehicle.

Everything off, drain is approx 57mA.

If we unplug BCM drain drops to 7mA

I cant seem to find any documentation or wiring diagrams for the BCM....

Boot release not working, indicators not flashing on unlock, front wipers not working. Faults may not be related

Anyone have any experience with this issue?

Thanks

Craig you are on it with the boot release!
very common,in fact did one 2months ago,
boot switch constantly "wakes" crappy french bcm unit unit overnight,hence flat batt
not sure about wipers?
can you connect scanner & actuate wipers?
bcm also suspect,it is a renault after all

Hi Keith

I have tried unplugging everything on the boot release, and we still see 50+mA drain.... Is this expected with connections off, ie BCM wakes when connection is open, or closed?

What was the repair in your case?

my fix was a boot release switch however sounds like yours has other issues
did you get to operate the wipers via handheld?

hi have you locked the car when checking current draw as bcm wont go to sleep until door locked
is it on of the keyles entry models if so put the key other side of workshop and see if drain goes after 10/15 Min's
