yeah that sounds about right. Went through the same stuff. You have to find out why your bcm is getting wet. Or else you’re gonna be in the same situation again.

 

Damn alright. Well thank you so much for all your help. I guess I'll go through with it and hopefully it works out. I'll keep you posted. Hopefully by noon tomorrow I'll be able to drive my car finally after almost 3 months.

 

Hi.

Do you know why when you initially took the car to be diagnosed, the dealership was not able to determine BCM was the issue? They did all that determination and still not able to find the cause. Why they didn't perform BCM test?
Sounds like you were still able to save money by getting a used BCM. I hope you can get the FOB reprogrammed. I mean reprogram vs partials key reprogram, why the difference in price. They're still going into the programming mode ..not sure why they're charging you arms and legs..

 

What they're going to have to do at this point is ring out the wires between the diagnostic port and the BCM to verify the diagnostic port is actually working. They can't just unplug the BCM and try connecting straight to it, there's no harness adapter for that, you access the BCM THROUGH the diagnostic port CANBUS + K line.

If they can connect to the ECM but cannot connect to the BCM to do a key registration that's basically all the confirmation they need that the BCM is probably damaged. However they'll still need to ring out CANBUS +/- and the K-line wires to the BCM just to make sure it's not a bad wire between the diagnostic port and the BCM.

Partial reprogram means they're only doing the key, full reprogram means they're also programming your FOB. If you have the iKey system (push to start) there is no partial option since it's all built into the fob and the key itself doesn't have a transponder RFID chip.

If you don't have the iKey system you can reprogram the fob yourself, it's easy and only takes about 2 minutes. You cannot reprogram the key yourself though.

 

Hey everyone.

The dealership was able to get the keys programmed and luckily it didn't cost me as much as the original quote. Ended up costing me 284 once everything was said and done. However they did find that the ipdm was faulty as well and wasnt sending power to starter. I ordered a used one and once I dropped it in I was able to start the car and drive it home! However, I then realized there was a few more issues with car. For one the ac wasn't working. I was able to get it to kick on once I refilled it but unfortunately it all leaked out over night so I'm guessing there must be a pretty significant leak in it somewhere. The second thing I noticed was when I went to drive home later that night the headlights didnt turn on lol. I checked the fuses on the ipdm and they were all good so I swapped back in the original ipdm and the headlights did work so unfortunately Ill be sending this one back and hopefully can buy a fully functional one. Once I have some time I will troubleshoot the ac some more and see if I can figure out what's going on there as well. It's seems crazy to me that the bcm, ipdm, and ac all went out unexpectedly like they did but I guess that's just life sometimes. There didn't even seem to be any signs of water damage on either the bcm or ipdm so I'm pretty stumped on what even caused it in the first place. Maybe some sort of power surge? Anyways, thank you all for your help and wish me luck on the ac.

 

That's great to hear. It sucks all of these issues hit you at once, but you managed to take care of them. I understand stuff breaks but it's strange indeed. Yeah, wondering if you had a power surge or maybe battery cable was became loose. Good luck with fixing AC, it doesn't sound like bad as busted condenser.. hopefully you can find the leak and fix it (also check the fill line valve, it's possible sometimes this is where leak can occur)
