Had a body control module go nuts in a caravan. Horn honking, wipers activating.
Body control is in driver’s door.
Wires in door jamb broke and were giving bcm bad information.
Saw this 3 times so far.
 
Nasty storm is brewing.
Shouldnt be long and the power will go out. Hope not, generator is too far away to drag over in pouring rain.

What year caravans were those ??

It's Fury Friday!
I checked my calendar this time :D.
Good morning.
 
Touching the battery cables together with the battery out diffuses the capacitors inside the computer and resets it to a basic level, then you take it out and drive it and it relearns your driving habbits and adjusts accordingly.

Want good grounds from engine to chassis, can even add an additional one. Stray voltage will make your car computer do crazy things, make sure all wiring is well insulated and not chaffing up against some sharp edge, even the high energy spark plug wires feeding back into the system. We are talking mili-volts here, electricity follows the path of least resistance to get back to the battery.

All connections clean and good, not green with corrosion, battery cables clean too. Test your battery want at least 12.5 volts, it is the heart of your whole electrical computer system.


I have found that inside the ECUs the capacitors start to leak over time, drain down on to the boards and now the electricity follows a new path goofing everything up. Rebuilders replace the capacitors, clean the boards, and reseal the boards with a clear sealer when all done.

The hard part is finding the good people to do this work.
I changed the battery January 2018. Around that time it did some freaky stuff with windows not working at times. I think the horn blowing started sometime after that. Wondering if when old battery was dying it got its brain scrambled a little. Guess I will see when I put the module back in. Lately it would go a day or 2 after putting horn fuses back in till it would start blowing.
 
Ahhhh .. Late summer in the southwest deserts. When the girls can be scantily clad night or day :rolleyes:.
Good thing they didn't choose the winter solstice for this event, they all be wearing parkas.
Want to get them out of there close down the cell network!
 

Thank you, that was awesome. But how did you manage to zinc plate the inside of the trunk ?

I have used a tank of water to remove rust from parts. Tank, water, and cleaning soda, one stainless steel plate, wires, and then hang the part you want the rust off, and I used the battery charger. Cleaned a tractor rim that way, that is the biggest part.

What is this a picture of ? Zinc plating mix ? Do you mind telling a little about it ?

Bill

The trunk latch on this 67 dart was cleaned and replated with New Zinc, in a process like electrolysis moving the zinc particles in the solution to the part you want to replate.

The current of 3 volts is used from a 12 volt battery charger on trickle. Polish it up a little at the end of the plating process. The zinc mix is something like vinegar, wash soda, zinc strips from the hardware store, and Karo Syrup of all things that helps bring out the shine in the plated finish. Have to let the mix soak for at least 24 hours so that the zinc particles gets absorbed into the solution from the vinegar breaking it down. Pretty cool how it all works, something I can do in house here without having to send things out. Have to see if I can dig up the actual recipe for the mix as it is buried somewhere around here.

The marvel of science . . . A process that is like the opposite of Electrolysis that is used for rust removal.

Still stormin. House is shaking.
Between thunder and wind its continous.
 
Went to visit a friend in Northern Virginia for lunch. Took me to a nice Vietnamese Pho Restaurant. The Pho was Excellent
