This page applies to Address 1B-Active Steering in Audi models such as the A4 (8K), A5 (8T), Q5 (8R) in addition to the newer A6/A7/A8 (4G/4H) models with J792 Component: DYNAMIKLENK.
Active/Dynamic Steering is NOT standard equipment in all of the models listed above. This equipment can be identified using PR Codes such as 1N7 - Dynamic steering or by evaluating the data in the Auto-Scan:
Address 1B: Active Steering (J792) Part No SW: 4H0 907 144 C HW: 4H0 907 144 C Component: DYNAMIKLENK. H06 0100
Address 1B: Active Steering (J792) Part No SW: 8K0 907 144 A HW: 8K0 907 144 A Component: DYNAMIKLENK. H05 0322
Coding
Coding for this Control Module is normally done via Software Version Management (SVM). If the old Control Module is still accessible read/copy it's Coding to the new Module. A Security Access code is required prior to Coding. If the original coding is zeroing after a key cycle please see the Special Notes.
Security Access
- 61378 Coding and Basic Setting enabling
Basic Setting
Prerequisites:
- Battery Voltage is 12.0V+
- Key ON, Engine at idle
- No fault codes other than 01087 - Basic Setting Not Performed
- Perform G85-Steering Angle Sensor Basic Settings. One the following pages would apply:
Continue Only after successfully completing the G85 basic settings above
- Leave the steering wheel in the straight ahead position during the next steps (Tolerance: ±1.5 °).
[Select]
[1B-Active Steering]
[Security Access - 16]
Enter 61378, to enable the basic setting.
[Do it!]
[Basic Settings - 04]
Group 101
[Go!]
[ON/OFF/Next]
- Basic Settings is active.
- If "No Value" is shown in the 4th field turn the steering wheel at a rate lower than 50°/s in excess of 45° using both directions until OK is shown.
- If "OK" was shown in the 4th field continue.
[Done, Go Back]
[Fault Codes - 02]
Check and clear fault codes.Cycle the ignition to confirm the controller is fault free.
[Close Controller, Go Back - 06]
Note; If the vehicle is equipped with Audi RCEPS Steering Assist make sure to complete the end-stop learn and check it for DTCs.
Replacement
- Replacement of the 1B-Active Steering (J792) control module requires Online Coding and Parameterization using SVM (Software Version Management). SVM is a system used by VW/Audi to flash update control modules, and in certain cases, to change their Coding, Adaptation and configure Parameters. VCDS cannot perform SVM.
- NAR (North American Region) market TPI 2029594 may be helpful if coding is not possible when attempting to code a replacement module on the dealer level.
Special Notes
- If the replacement module is accepting coding but zeroing the coding after the ignition is cycled, try coding it twice followed by Basic Settings without closing the diagnostic session.
- NAR TPI 2021194 is related to a crooked steering wheel in conjunction with 01087 Basic Setting Not Performed and 03263 Functional Restriction DTCs for A4 (8K) and A5 (8T) models with hardware part number 8K0 907 144 A. The software level is flashed using SVM from level 0322 (or older) to 0570 or higher.
- NAR (North American Region) market TPI 2026507 pertains to DTCs 03221 Safety Lock for Active Steering: Mechanical Failure and 02538 Function Restriction due to Overload. The problem is a faulty steering column lock magnet and a repair kit is available for some models. After the steering column repair kit is installed the software level must be updated via SVM to a level greater than 0580 in the A4 (8K), A5 (8T) and Q5 (8R) chassis. At the time of publication the A6/A7/A8 (4G/4H) models did not require a flash update. Make sure to check the Factory Level Repair Manual for the vehicle in question.
- DTC 02538:
- RoW TPI 2028500 mentions the DTC 02538 in conjunction with specific Freeze Frame details and vehicle production dates to confirm if the document is applicable. When applicable, replacement of the1B-Active Steering (J792) module (instead of flash updating) is mentioned.
- NAR TPI 2029282 mentions the DTC 02538 in conjunction with specific Freeze Frame details and vehicle production dates to confirm if the document is applicable. When applicable, replacement of the1B-Active Steering (J792) module (instead of flash updating) is mentioned.
