Will VSP credentials nullify the need to solder to chips to program some cars?

David Diagnostician Georgia Posted   Latest  

I have not ran across the need yet as my IM508 has great coverage so far when I need to program keys doing so just OBD2, BUT I have always wondered if having VSP credentials would take out the need of removing modules, opening the case, and soldering to chips to program keys on the more exotic security systems. I also have the XP400 Pro

I tend to try and work smarter, not harder.

Much appreciated..

Yes and no. It depends on the car. For some cars, like … Toyota cars, you will (probably) need to get to the EEPROM and reflash it with a virgin file. On other cars, like all 2004 and newer Toyota cars, you'll be able to avoid flashing the EEPROM if you have credentials. I'd strongly urge you to get the credentials. It will make life easier if you do this type of work. There are also…

I currently do have VSP credentials, only used once. So in the case of older Toyotas I cannot use these credentials as a magic wand?

Unfortunately, no. The official procedure for the early cars is to replace the immobilizer ecu. The aftermarket usually reflashes the EEPROM instead. The AutoProPad has a feature where you can virginize the EEPROM through the OBDII port on some cars. I've never actually used it, but I've been waiting for an opportunity ever since I saw the option. The Techstream cannot communicate with the…

Not on those old ones in the event of an all keys lost situation. If doing a used control module or an all keys lost you are doing eeprom work. A replacement controller from Toyota comes in learn mode ready to learn keys and is Toyotas official solution to all keys lost on the older vehicles. Having an LSID allows you to do whatever the OEM intended using fro t door methods. There are times…

SKP-900 (and potentially others) will put that immobilizer in a virginized state. Its a 20 minute lock-out and it comes back in an unprogrammed state.

Id say no. The most useful things about eeprom is to do stuff outside of what oem level allows. “I tend to try and work smarter, not harder.” To me in many cases eeprom methods are the smarter and easier method. It may seem scary or difficult at first but truthfully once you get familiar with it there is not much you cant get done. Whats more powerful then OEM access to tools/software? That…

Well, I'm going to respectfully disagree. I've seen multiple boxes totally ‘effed-up’ by people who supposedly knew what they were doing with EEPROM work. I've seen PCMs where the gel used to seal it was totally destroyed. Or the solder joints were intermittently having issues, installing an issue where none existed before…it's not a guaranteed fix by any means. Like anything, it's a matter of…

Timothy, this is an interesting perspective, and a separate discussion post with pictures of not-so-successful “Eeproming“ aftermath would quite insightful.

The first time I experienced an issue with an EEPROM swap, was an older Dodge B3500 van, (a common failure way back when, early JTEC box). The client had sent it in to the rebuilder for EEPROM repair. When it came back, the cover on the box had been cut open with some kind of cutting tool and folded back. The gel was gouged out. The cover was then folded back down, and sealed with silicone and a…

Certainly makes the swapping of the module with a new one seem like a more viable option. Especially if you suck at soldering/resealing modules.
