Replacing a BCM on a 2017 Ford Escape without performing a Parameter reset or key learn with a scan tool

2017 Ford Escape SE 1.5L (D) 6-spd (6F35)
Security Theft / No Start

This vehicle required another BCM, a donor used BCM was provided. After programming the BCM with as built data it was left with a no start because it requires a parameter reset/key learn. This is a LSID vehicle where it will require an LSID number and two high-security keys to learn into the BCM. Instead of performing a parameter reset it was decided to Eeprom the BCM over from the original BCM to the Donor. The BCM was taken apart and the target device was found which holds the key string information. The target device was a "95320 Eeprom" in where the data from the original was written over to the donor BCM's Eeprom. The BCM was then put back together and the vehicle started without having to perform a parameter reset/key learn. The benefits here are 

  1. No parameter reset or key learn required with an IDS or FRDS factory scan tool 
  2. Only one high-security key was required not two 
  3. ​No LSID required 
  4. No waiting for Ford to fix their IDS or FRDS software (which seems like they have been having lots of issues with.)

There can be lots of tools in a tool box, Its using tools to get "inside the box" that might help repair a vehicle

Nice work Kevin. As someone looking to get more into this type of work can you recommend an eeprom reading tool for someone starting off? Kind regards, Carl

Good stuff, Kevin. Thanks for sharing this process. Could I ask how you were able to determine which chip contained the key information? Is it just a trial and error thing or does it come with experience?

Not for nothing, but wouldn't a tow to the dealer and a half hour labor charge be faster and cheaper? How does this effect the part's warranty coverage?

Tow it to the dealer? really ? So they can tell you a used module isn’t possible and sell you a new one... so you can pick up the vehicle and suddenly the invoice isn’t a half hour it’s far more...or so they can call you and tell you their software doesn’t work and “Ford” doesn’t know when it will be fixed , and now you have to call ”your customer“ to tell them it has to sit at the dealership…

I make it a point to tell my customers to never send their customers to the dealer. Nothing good ever seems to come from an interaction with a dealerships service department. I have seen the dealerships go through the glove box and find contact information on the owners car and then contact them to try and solicit business off my customers. The dealers are always marketing themselves as being…

Kevin, How much would the vehicle owner be charged for this service? and what kind of turn around time would be expected? There are hack dealers out there but not all of them are that way. Having a working relationship with a trustworthy supplier is crucial in any business, If you specifically asked for a parameter reset and learning of keys why would the bill all of the sudden…

Its great technology that can allow for this workaround. Learning about is interesting. Not trying to rain on your process it just seems like a lot of time and equipment for a process that can be performed by a VSP through normal channels. Being able to present the process for learning purposes helps everyone understand what's actually going on in the modules. I just don't see it as a practical…

No feathers ruffled it’s all good. Remember it wouldn’t just be a 1/2 hour charge at the dealer ... they would have to add that $450+ dealer high-security key since the customer only has 1 key!

A used module could likely have the existing key added as long as the keys stored in the module were not erased. Then parameter reset should allow for vehicle to start. This method has saved me numerous times with used modules when only 1 key is available.

Hi Kevin, With all the mayhem out there right now, you are on the cutting edge of what we may be facing as an industry. In other regions of the world they don't have the software resources we do.

Yes you can remove and swap the Eeprom ..(that would have also worked.) I don’t like removing devices unless I have to ... and sometimes you have to ... but in this case it wasn’t necessary

In addition to that. The whole purpose of parameter reset routine is for the modules to exchange bits around. (American called it shaking hand) but what is happening is an exchange of bit around modules. So they can have the same data package in sync. Modules are talking to each other.... The LSID is an scam in place.

Hi Kevin Is it easy to damage the replacement bcm if you have to soldier the chip in? Like meaning circuit board damage. I dont know much about this process...like special tools,special soldering gun...etc Nice post and thanks for the information. Very fascinating!

Joseph learning “Eeprom” will enable you to determine which device holds the information required for certain decisions whether its holding the security information or the calibration loaded in that given module. It takes some time and experience to be able to identify where and which device holds this information and sometimes it involves reading the device and looking for certain address lines…
