My BCM is faulty. How easy is it to replace myself?

[onions]

So I took my car in to the dealer for a faulty door sensor issue. The car would think the driver door is opening and closing while the engine is on and/while I’m driving. Nothing consistent it just starts happening randomly. Dealer says it’s the bcm and that it needs to be replaced. How easy is it for me to do myself because he’s asking for $1400 to replace it.

Why is this not covered under warranty? Are you over the 3/36k?

Yeah it’s a ‘17.

800,000 Accords have been recalled for the BCM. Can this help convince Honda to do something for you?

I don't think you can install it yourself unless you have a capable scan tool to code the new BCM.

Its not that hard at all. It's located next to under dash fuse box. Your keys would need to be reprogrammed to the new bcm.

The last two posts confuse me. Do I need a scan tool of some kind? I assume the dealer has to reprogram my existing key fob? Is the the reason I need the scan tool?

You need something like this:

$1,400 seems a bit excessive to replace/reprogram the BCM, I would definitely check out a different dealer.

I too am having electrical issues as my dash lights are flickering nonstop and draining my new batteries every time.

i assume then that that thing do more than just reprogram keys?

You will need to have this done at the dealer. The immobilizer system is part of the BCM, so we need to use the dealer scan tool (HDS) in order to tell the car we are replacing it. Replacing the BCM is not hard, but the car will be a paper weight as soon as it's done and will not start in your driveway until the keys are programed to the car again. So if you are trying to save money, you could always replace it yourself by ordering online and then towing the car to the dealer and have them program the keys, usually 1hr of labor at their shop rate.

But more important to the issue, did the dealer replace the door sensor or no? It's one 8mm bolt and takes all of 30 seconds to replace.

How long will it take to reprogram it if you don’t mind me asking.

Depending on the work load of the shop, maybe an hour or so wait, the actual job to program the keys/immobilizer takes about 5 minutes.
