Big Problem with Steering Wheel Control Module

[bmwww]

Hi , i have big problem with my new SWCM . I change my original control module

1K0-953-549-AE Type 2 SW 0070 Lowline Yes - -

with new control module

1K0-953-549-AQ Type 2 SW 0070 Highline Yes 1.3 -

but this module not work correctly . When i Coding from old coding 0000002 to new Coding 0000022 my horn work non-stop when i turn my key in possition on . When i start the engine my horn stop work . Where is the problem ? I change this SWCM for Cruise Control but also my Steering Angle Position Sensoir not adaptation with new module . My Slip Ring number is 1K0-959-653-C and my Steering Angle Position Sensor number is 1K0-959-654 . Where is the problem ?

If you had a low line module you have no lin bus diagnostic communications wire to the CECM. You need to run a diagnostic wire so the steering module can communicate with the rest of the car correctly.

If i change this Highline control module with Midline - everything will ok ? I don't wanna have board computer or multifunction steering wheel . I just wanna have Cruise Control .

 

[MJ]

No, you need to run the diagnostic wire which your original module didn't require.

 

[bmwww]

How ? Can you help me ? I must run diagnostic wire from ? to ?

 

[MJ]

When you buy the genuine cruise control kit it comes with a wire that's required if you had a low line controller. This is installed between the steering module and central electronics module to allows communications.
There will be a guide on the Internet somewhere of where it needs running then how to code it. they're the same as a mk5 golf.

Hm ... Of wiring jack of SWCM i have 9 wires . from pin 1-10 missing and pin 14 missing , i have 11,12,13,15,16,17,18,19,20 pin's . Where must i put this wire on who pin of SWCM to who pin of CECM ? I forgot to say that my Cruise Control works with the new module.

 

[MJ]

pin 13 is the wire so that's not the issue. do you have buttons on the wiper stalk?

 

[bmwww]

No i don't have buttons on the wiper stalk but i don't wanna have board computer or multifunction steering wheel - i just wanna Cruise Control and i have Cruise control but with the new SWCM my Horn work non-stop when i turn ignition on position ON and when engine is started my horn not work and have fault code 00889 Horn Short to ground . Also my steering angle position sensor not adapt . with new control module .

 

[MJ]

Did you change the slip ring to a different one?

 

[bmwww]

No , my slip ring is 1K0-959-653-C Type2 . My new SWCM must work with slip ring Type2 . This is my old SWCM.

1K0-953-549-AE Type 2 SW 0070 Lowline Yes - -

this is my new SWCM

1K0-953-549-AQ Type 2 SW 0070 Highline Yes 1.3 -

They are identical and must be interchangeable ? I check here http://wiki.ross-tech.com/wiki/index.php/Steering_Wheel_Control_Module_Versions and don't see problem . Or maybe my new SWCM work with slip ring 1K0-959-653-D ?!

 

[MJ]

What is the spec of the car and have you tried different coding such as

0001022

 

[bmwww]

Yes i tried different coding . When i coding 0002042 horn not work when i turn ignition in position On and everything ok but also not work when engine is started . When i Coding 0000022 (rear wiper install and cruise control) my horn work in ignition position On and stopped work when engine started . This picture maybe help



maybe problem in my slip ring ?

 

[bmwww]

With new Control Module

1K0-953-549-AH Type 2 SW 0070 Midline Yes - -

again problem . No Cruise control and Steering angle sensor not adaptation . Why ?

Hi, I know this topic is so old, but I troubled same problem as the author. I have a VW golf mk5, I would like to retrofit the CCM to my car. Originally there was the following SWCM in my car: 1K0 953 549A - Midline with 1K0959653 clock spring. I replaced it to the following SWCM: 1K0 953 549AQ - Highline with 1K095653C. I had to set up the controller wire (Pin 13 under the steering wheel black connector to Pin 4 blue connector under the window wiper). After the setup, I modified all necessary value in the VCDS and I released the horn doesn’t work. I checked many forums, but nowhere found the solution.

But here you can or someone who will need this information will found the solution:

Unfortunately there is a little bug with 1K0 953 549AQ SWCM, This SWCM is highline there isn’t matter the multifunctional steering wheel option switches off in the VCDS, the SWCM handle always multifunctional steering wheel option… Therefore the 1k0971584 type of airbag harness is not suitable for this SWCM, because the airbag pin is different position of the clock spring connector as the lowline module. (I disassembled the 1K0971584 airbag harness and but the horn 12V wire right position, but it also not working.) Therefore I replaced it the 1K0971584C type of airbag harness (this type is include the Multicontrol steering wheel modul connector) firstly I tried it and still not working, but when I connect the cable for the MCSW modul (1P0950542) the horn is working and the horn is perfectly working.

So if someone is buy AQ SWCM, they also have to buy 1K097158C type airbag harness wiring and 1P0950542 multi contour steering wheel modul and everything will be work appropriately.
