Manually light up the dash to wake up CAN system on a Bentley Continental GT 2005
Hello Mates,
Can anyone help me by showing me which fuse or relay to jump (and how to jump) in order to manually light up the dash to wake up CAN system on a Bentley Continental GT 2005.
For now I cannot put ignition on because of the steering column which is locked and in order to access and program the Kessy I need to wake up the CAN network and to do that I need to simulate an ignition ON status..
From Bentley IETIS it may be around the 433 ignition relay (C00296 socket X00477), But I dont know if I should send ground to terminal 85 of this relay, or if I should send Terminal 30 to Terminal 87 directly.
Presently on X00477 socket I have T30: 12V T87: 0V T86: 12V T85: 11.51V D: 0V
This is only to power up the system, kind of like holding the brake pedal down for 20 seconds while having the turn signal on while holding the high beam stalk toward yourself.
I did all of the above during my rebuild, and the vcds would not make it through a full scan as the power would cut out in the vehicle eventhough I was still holding everything in place as described above, so I did as you are suggesting, I powered up the Instrument cluster by way of a jumper from say a body fuse that has full-time power to fuse #27 or #54 iirc, there is also #23, but just to note, I only picked one of the three, NOT any combination of the three.
Hello @Dark Green ,
This is NOT a security issue, as if you do not have proper keys, the IMMO will not allow for the engine to run..
It's about the Phaeton but the system is identical to the CGT, and it describes doing what you're talking about.
On my car the CAN-Bus is live all the time, even with ignition off, and even if it has gone to sleep, it should awaken as soon as an OBD device is connected.
Not sure I feel comfortable discussing bypassing the security system in any more depth on a public forum.
Hello @Dark Green ,
The link you posted comes up blank...
Also the issue is eventhough the CAN-BUS may be active, pin #16 on the OBD port is missing power when the key or Instrument cluster is not powered up, holding the brake pedal down only works for a short period, at least in my experiences .
Also, even if the CAN-BUS is active may be from Terminal 30 (OBD pin16), Kessy ecu is not accessible from the tool I use (ODIS V5.2.6).
This is the point and probably it is because of the lack or Terminal 15 in Kessy, and why the dash has to be set ON.
I knew about powering up the Instrument cluster by using a jumper just like what is done for this all key lost Touareg car that uses the same Kessy component
Your informations are comprehensive and hopefully will help me to put ignition on in order to be able to reprogramm the Kessy ecu.
exactly what to do in order to wake up carefully
Hello Johnny,
When it comes time to take action I wonder
1- whether to keep the three fuses in place when injecting the Terminal 30 signal
2- in case you have to remove them, on which side of the fuse do you need to inject Terminal 30
3- whether you remove the fuses or not, you have to keep the jump in place throughout the programming work, or do you have to inject Terminal 30 stealthily, (like the video
I did not remove any of the fuses, I just applied power to # 54, or it may have been #27, but I am really thinking it was #54 as one of my pictures shows the jumper from one fuse to another in the area of 54.

Yes you are right its #54
The jump has been installed all the way for more than 1 hour now.
Presently the data inside my kessy seems to be corrupted.
So i am looking for a way to work around this issue.
i will probably create a new thread for this issue.

Hello @kilog ,
I received your message, please tell us what led to the situation, what were you trying to do, you said that all three original keys are not recognized, and that you were trying to get the pin/skc with FVDI, as your VAS 5054 was down..
So please explain why you were attempting to get the pin skc from the KESSY if the KESSY and all keys are original, or did you change out a damaged KESSY module.
I do not read the KESSY module IMMO pin/skc with FVDI or VAS, I remove the actual KESSY module from the vehicle and de-solder the 93C86 eeprom from the board and read it with carprog to get said SKC as pictured below, it will give you a four digit code that you would place a zero in front of to have the required 5 digit code.
EDIT: Also, if you have not done anything with the KESSY module as far as replacement, have you pulled the carpet up to inspect the KESSY module area for water, or to see if it is corroded from water damage ?

Reason: Add picture
Finally I disconnected the Kessy and unsoldered the 93c86 eeprom.
And guess what I found: NO KEY configured
In the attached picture it is read from Carprog.
Can I program the keys with Effi (ZedBull software) and how?
Before detaching kessy from the car (the place was excellently dry) I tried SBB without success
I also host SKP-900 tool
as well as Mini900 and KeyDIY
I know there is a solution to generate the keys with Tango. but I dont have I have
Gambit programmer car key masterthe device before Tango still from Scorpio
OK I am in the middle of a job right now, but being that you have the pin/skc code from the KESSY and the 3 original keys to that original KESSY, correct, then you would use the Roas-Tech as I did to re-pair your 3 original keys back to the KESSY module because you now have the Secret key code...
Sorry this was text to speech so I hope it's ok.
Hi Johnny,
You are amazingly fast to answer!
Tkhs bro...
So you mean Ross-Tech VCDS right?
I do have it.
Can you tell me how I should do it?
Is there a thread that already solved this issue

I am in the middle of cutting marble right now, give me an hour please.
[Select] [05 - Acc/Start Auth.] [Meas. Blocks - 08]
Select Block 081. [Go!] The first 17-digit string is the VIN. The second 14-digit string in the Immo-ID.. [Done, Go Back] [Close Controller, Go Back - 06]
Key Matching
Prerequisites:
Battery voltage at least 12.0 V. We strongly recommend the use of a battery charger.
You can match up to 8 keys.
All keys are either new or were adapted to this car (IMMO-ID) before.
While adapting each key, make sure to place the other keys away from the ignition lock (reader coil). The passenger seat is an adequate place.
If all Keys are new OR the first inserted Key is new, the Ignition will NOT switch ON with this key.
Put the first Key into the ignition Lock, but do NOT switch ON the ignition.
Press and Hold the Brake Pedal for 20 Seconds to wake up the Diagnostic Databus.
[Select] [05 - Acc/Start Auth.] [Meas. Blocks - 08]
Select Block 022. [Go!] The value in field 3 must be 1. If value is not 1, the key is not capable of being adapted to Immobilizer. You can check each key in this manner.
Select Block 023. [Go!] Make sure the shown lock times in field 1, 2, 3 and 4 are 0 (each field represents a time in minutes).
If the lock times are NOT 0:
Do NOT switch off the ignition!
Allow the car to sit for AT LEAST the number of minutes that were indicated by the fields 1-4.
[Done, Go Back]
[Sec. Access - 16]
4-digit PIN
Enter zero followed by the 4-digit PIN. For example, if your PIN is 1234, enter 01234.
7-digit PIN
[Do it!]
[Adaptation - 10]
Enter 21 in "Channel Number". [Read] The "Stored Value" is the number of keys currently matched.
Enter a "new value" corresponding to the total number of keys to be matched, including any existing keys. The old keys are automatically being cleared. [Save] [Done, Go Back] [Close Controller, Go Back - 06]
Repeat the following steps until all Keys have been matched:
Switch Ignition OFF and remove Key, Steering Lock should engage.
Insert the next Key and switch Ignition ON.
The Immobilizer Warning Light will light up for ~2 seconds, wait until it goes out.
Note:The above steps after saving the adaptation, should not exceed 60 seconds withing matching 2 of the keys and having one key in the ignition should not exceed 30 seconds!
Hi Johnny
Thks for your contribution
So by using this trick "Press and Hold the Brake Pedal for 20 Seconds to wake up the Diagnostic Databus" I dont need to jump fuse #54 any more right?
