Bricked 2011 Prius in need of Virgin Dumps

**freefallingegg** · 17th October, 2019, 03:57 AM

I should start by saying that I wouldn't have found this forum without my current problem, so that is my silver lining. Through reading this forum, I have learned very much. For that I am thankful.

My problem is this...

I have an "all keys lost" situation, despite the fact that I have one original key. It is simply not recognized by my vehicle. Anything I try to do concerning the SKS in Techstream results in "lost connection with the ECU..." I believe my original parts have corrupted code. This is my personally owned 2011 Prius ZVW30L-XEBA. I can post my dumps if requested, but the transmission code (RH 56) is literally ALL 0's and almost all of the certification ecu (93C86) is ffff.

I've searched extensively on the forum but I can't find copies of the original virgin dumps for these parts. I have only found mentions of them and password protected versions. I should mention that I have also found a lot of information surrounding the subject.

Certification ECU is part #89990-47051
Transmission ECU is part #89535-76020

I need the original virgin code for these parts.

Any help anyone can offer will be most appreciated.

I'm looking forward to joining this extremely resourceful and amazing community.

Thanks all!

Mike

Hi is it a jap import or a uk car ?

I will keep an eye out for an ECU set.

I'm in US. So, jap import? I'm guessing.

Also, if anyone wants to teach me how to make any sort of sense of hexadecimal code in immobilizers, I'm all ears. I understand the basics, but I have no idea what is what (key codes, vehicle ID, virginizing code, etc...) within the code. This Gen 3 Prius code has a good many lines to the Certification ECU Module. The Transmission Control is far more basic, but I still don't know what is what (mine is all 0's.) I REALLY like to learn new things.

Thanks all!

Anyone?

Just so everyone knows, I called two locksmiths and neither could program a new key despite a great deal of time and effort.

Sorry, but I need help... Sooner than later... . I'll gladly contribute if/when anyone needs anything which I have to offer.

I'm growing desperate.

So this just happened by itself?
No work on the car, updates or programming?

Key should work touching the button with the key. If keyless function fails.
If one of the modules are failing. It needs to be swapped. And things needs to be synchronized.
But this costs money. No cheap solutions available. Experienced Locksmith, Car electrician or Toyota dealer.

Buying second hand kit from the junkyard, is probably the cheapest way out of this.

Key stopped responding. Even when held against start button. I tried a smart code reset to program a new key, but the cert module doesn't respond to Techstream. Upon reading the EEPROM, the code looks very much currupt. Most of the code is missing and is all "ffff". There are zero saved immobilizer codes in it.

I replaced the original with a used module, which will talk to Techstream, but smart code reset fails, as does adding any additional keys. The ignition will turn on with the replacement module in, but no "ready" or start. I'm attaching the dumps from both modules. #1 is original (corrupt) and #2 is replacement that will not reset or allow for additional registration of smart keys.

I am treating this as "all keys lost."

Locksmith was unable to program new key. Yes, I could eventually afford to purchase new Cert and Transmission modules, but I'm hoping to avoid that $1,150 US cost and loss of a vehicle in the meantime.

Ideally, I would be able to find the "new condition" dumps from both modules (89990-47051 and 89535-76010) and reprogram them to be "new." I have the means to do this. I DO NOT have the financial means to purchase new modules and will not for a good long while.

My tools are Techstream Lite and an EEPROM programmer. If you have any suggestions for what to try next or for affordable additional tools, I am all ears.

In addition, I am most appreciative of your reply.
