Difficult case, you would have to hook up another lock for a test, possibly a steering or comfort module, because sometimes without backing up these controllers/modules it is difficult to fix the car.

Hello, I checked these microstokes. Values on the attached 0 Ohm, on the open in the range of 640 Ohm. Is there something I should further check? Auto starts normally. The only problem is that the steering wheel lock does not engage....

DoctorCar · Answer

Converted installation in the car and now does not block the lock. There is a trick for dead locks without fixing them, but then it no longer locks it at all, but it smokes drives and pops up a message on the dashboard when extinguishing.

Someone tells me that the lock is not getting the right signal from other controllers, that's why it doesn't lock........ What do you guys think?

kszychu · Answer

I found such a provision on the web, sorry for the translation... In order to increase safety requirements, the release of the electronic steering column lock must be authorized by three separate control units.The following conditions must be met:● Authorized key must be recognized by the imobilizer. ● Data bus diagnostic interface J533 (speed = 0 km / h; rpm = 0 rpm) ● Steering column electronics control unit J527 (terminal 15 off, speed = 0 km / h) ● Central comfort control unit J393 (terminals 15, CAN signals from J533 and J527 OK) ● Input and output authorization switch E415 (Contact S, terminal 15 off) ● Electronic steering column lock J764 (checks that both speed signals from J533 and J527 are OK) Electronic steering column unlocks when authorized key is recognized by immobilizer. Pools 15 and 50 are activated only when the electronic steering column lock is enabled

In my case, the fault was in the steering wheel module.

In the immobilizer module, group 005 I found something like this. Address 25: Immobilizer (3C0 959 433 R) 10:34:32 Group 005: Electronic Steering Column Lock (ESCL) II 1.0 ESCL Status Mode ON ESCL Status (Unlocking Bit) OFF ESCL Status (Locking Bit) Does anyone know what this is responsible for? How can one change OFF ESCL Status (Locking Bit) to ON ESCL Status (Locking Bit)?

kszychu · Answer

A breakthrough in the case! I swapped the gateway gateway. I put in from another b6 but the swapped one is 7bytes. No. 3C0907951A and the lock started to lock. The non-functioning gateway is a 10-bar. No. 3C0907530L

Unfortunately can't dock the damn gate. I'm uploading pictures of the coding of the one that doesn't work. Added after 1 [minute]: Is there something that is badly off? I think my vcds is some limited , rice.

Launch78 · Answer

and what kind of error you have on this new one

kszychu · Answer

On the new one I have no errors. The lock works. The sec is that this 10 byt(orginal) I can not code to make the lock work. According to me . Wrong coding , or my vcds does not show all options. Or a third broken gateway. Before I buy the next gateway I want to rule out the first two options Added after 39 : Ppddisplaced gateway returned to donor

Launch78 · Answer

the coding of your org is ok , and what coding do you have in the steering column

kszychu · Answer

Can't connect to the column.... Added after 3 [minutes]: Coding gw I can change, it accepts without problem Added after 1 [hour] 20 [minutes]: I found a picture of gw byte 7 encoding on touran forum. There in point 4 there are 4 bits. In my case there is nothing in point 4. Maybe here is the problem. How to actuate, add these bits .

kszychu · Answer

1:0 for us!!! The lock works. Repeated attempts at coding had no effect. So I purchased a new gate with the tipM. After replacing the gate and coding, no errors in the gate and immo. However, I think something is still wrong. Because on the old gate as well as on the new one, unchecking the list of installed 2B modules brings up the error 02811 - Control Module for Electronic Steering Column Lock (J764) . In addition, I still can not connect to it. . Anyway I close the topic. Thank you all for the pertinent and not pertinent hints.
