EHC ?
- Thread starter strtjkt
- Start date
not to step on eric's toes but to take it a little farther, the EHC is the computer module that controls the function of the electrical system. seeing as how you have an '07 you might want to check to see if the service bulletin was done that involved the replacement of the old style EHC under warranty. you would do this through you local dealer. the new style has a USB style port on it instead of the old round style port to plug in the diagnostic computer. but like eric said, it can involve a wide range of quirks, but don't jump the gun in thinking that the EHC is the culprit for anything electrical. most of the time the problems can be traced to something as simple as a loose connection or a weak battery.
well put I really didnt know where he was going... do a search there is alot of info on ehc,, but now every time something goes wrong it gets blamed,, start with simple stuff.. keep all elect conections dry & apply dielectric greese.. a word of advice wires plus I plan on it as soon as warrenty is out..:2thumbs:

i may have just put my foot in my mouth. i have yet to find anything more than the service bulletin regarding the flash and reprogram of the EHC to correct the lockup of the speedo. best thing i can suggest is to either give big dog a call or have stealer contact them. sorry to get anybody's hopes up .

Insert title here...
Is this the bulletin you're looking for?
I think this came out previous to the '07's so you should be good to go although there's no harm in making sure...

Damn, what a open ended question that is never ending!
Let's see, where should one start......
The EHC (Electronic Harness Controller) is exactly as it is described. It is a microprocessor driven, electronic electrical control device that controls most of the electrical system operations, whether manual or automatic functions. The units have had many revisions, while trying to eliminate problems and "gremlins". Some have never shown their owners any problems whatsoever, but the bulk of the EHCs have proven to be very temperamental, to say the least.
The best advice you'll get from most here will be the following:
1) The constant use of a battery tender is MANDENTORY!
2) Annually do a "Load Test" of your battery and replacing it when it test "weak" or starts shows signs of being weak.
3) Do a search in the "How-To" section on weather proofing your electrical connections and components internal circuitry and circuit boards.
4) Don't Do electrical add-ons until you check with the dealer or others here about it's compatibility with the BDM electrical system!
A little time on implementing these things will save you from a lot of hassles down the road! :2thumbs:
There are also those of us here that can help you troubleshoot your problems, if and when they occur.
And as far as any of the Recalls and Service Bulletins go, request them from any BDM Dealer, and they should be able to help you out, or do your own search at Safercar.gov
And if all else fails, and you can't get the EHC problems corrected, there is an aftermarket replacement manufactured to take the place of the EHCs.
It and all of the needed conversion parts and instructions are sold by one of our members here, bdmridgeback a.k.a. Jake, on his web site: | | LOW DOWN CHOP SHOP | Big, Parts, Dog, Some, Until*-*Low Down Chop Shop
Hope this helps your understanding of the EHC out a little bit. :2thumbs:
