ab350z Posted April 6, 2008 Share Posted April 6, 2008 Wierd wierd problem with the Z today I wanted to run past you guys. Was away down to shops, got in the car and noticed the traction control and SLIP lights were on, so pushed the button to switch off and nothing happened. Then noticed no heating, electric windows or mirrors, lights or wipers were working. Managed to drive, did my shop, came back out thinking maybe it was a one off, still nothing. Main lights went on with the switch, then couldn't get them to switch off!! Away to disconnect the battery as the lights won't switch off!

Beavis Posted April 6, 2008 Share Posted April 6, 2008 Never heard of that one before, like you say best to disconnect battery for a small while then re-connect to see if that solves/resets the problem, may be even a problem with the battery.

Stew Posted April 6, 2008 Share Posted April 6, 2008 As I said in the PM Chris, it is a strange one. Clutching at straws here but once the battery is reconnected does the ECU automatically reset? Would that even make a difference.....????? Could it be water migrated into some box that houses switches or something? Quote Link to comment Share on other sites More sharing options...

Sounds more like the BCM body control module as gone tits up, like i said you can only try the battery disonnect at present, but have heard of strange things happening when the battery is on its last legs.

ab350z Posted April 6, 2008 Author Share Posted April 6, 2008 Battery is disconnected now. Alarm was blaring last night for a bit and its done it before when it snows. Maybe just doesnt like cold. Maybe a fuse gone? Lights, wipers, windows and central locking gone. Mirrors, radio, alarm and displays all work! Random! Quote Link to comment Share on other sites More sharing options...

Not sure bout the BCM is down in one of the footwell sides i think, any seepage of water in these areas? Quote Link to comment Share on other sites More sharing options...
Stew Posted April 6, 2008 Share Posted April 6, 2008 I think we are thinking along the same lines Beavis - you just knew the proper name! Quote Link to comment Share on other sites More sharing options...
ab350z Posted April 6, 2008 Author Share Posted April 6, 2008 Just away to reconnect battery and check for leaks, nothing obvious when I got in but not the kind of thing you think to look for when popping to the shops!! Quote Link to comment Share on other sites More sharing options...

To be fair if there were any leaks they would be behind the kick panels. Quote Link to comment Share on other sites More sharing options...

Beavis Posted April 6, 2008 Share Posted April 6, 2008 Its alive!! Back to normal. Phew! Cheers guys. Good news Keep an eye on it and it may be worth getting the battery checked out. Eroneous voltages can play havoc with electronics. Quote Link to comment Share on other sites More sharing options...
Stew Posted April 6, 2008 Share Posted April 6, 2008 Stick a volt meter across it to check the output. At least you'll have an idea! Quote Link to comment Share on other sites More sharing options...
M13KYF Posted April 7, 2008 Share Posted April 7, 2008 hope you dropped your windows before disconnecting the battery Quote Link to comment Share on other sites More sharing options...
Beavis Posted April 7, 2008 Share Posted April 7, 2008 hope you dropped your windows before disconnecting the battery You would think if it was that important to drop your windows if you disconnect the battery, they would put up a notice by the battery. Not sure if i disconnected my earth lead when fitting grounding kit but nothing untoward happened. Quote Link to comment Share on other sites More sharing options...
bigphil Posted April 7, 2008 Share Posted April 7, 2008 definately have the battery checked, the ECU doesn't cope well with voltage drops and the scenario you have given is classic when the battery doesn't have enough cranking amps available.
