How to Calibrate Steering Angle using Tool32

Bali · Sep 16, 2020

This describes the steps needed to reset/calibrate the steering angle on the ASC or DSC module in your E46 using a program called Tool32. This may be needed in several different situations, but most commonly after repairing the front steering/suspension or replacing the DSC module. You must already have BMW Standard Tools installed and working properly.

Steps

Center the steering wheel
Start C:\EDIABAS\BIN\TOOL32.EXE
Click File in the menu at upper left
Click Load SGBD, Group file
Browse to and select the corresponding .PRG file for your DSC module family
- Teves MK20 DSC: C:\EDIABAS\ECU\DSC_E46.PRG
- Teves MK60: C:\EDIABAS\ECU\DSC_MK60.PRG
- Bosch 5.7: C:\EDIABAS\ECU\DSC57.PRG
Look in the list of jobs for one containing lenkwinkel
- Teves MK20 DSC: lenkwinkelsensor_id_dsc_schreiben or abgleich_lws_aq_sensoren, whichever succeeds
- Teves MK60: lenkwinkel_dsc_abgleichen
- Bosch 5.7: test_lenkwinkel
Double click the job
Check that it succeeded
Done!

Notes

If Tool32 doesn’t work properly, you may need to register a DLL, like so.
- Open administrator command prompt
- regsvr32 “c:\ediabas\bin\msflxgrd.ocx”
Determine which ASC/DSC module your car has (USA only)
- 323/328: MK20
- 325i/325Ci/330i/330Ci: MK60
- 325xi/330xi: Bosch 5.7

This is a note for those with a SAS (steering angle sensor) swapped from another car.

I was doing a remote session with @danny.323i today on his 05/1999 323i MT, and we kept getting an IFH-0009 error from tool32 when we ran the lenkwinkelsensor_id_dsc_schreiben job in tool32. Link to his thread.

Hello, I have a yellow DSC light that comes on at about 15mph and saw that my SAS reads at -1440 through INPA. However, it lacks any of the commands like shift +f4, or shift +f8 to be able to follow through with calibrating the sensor. Does anyone have any idea where I can find older versions of...

After some digging with INPA I saw that the VIN in the SAS did not match his car’s VIN. In fact, the SAS was actually from a 07/1999 328i. Even more digging revealed that his IKE (instrument cluster) had also been swapped from that same 328i and he had the tamper dot next to the odometer.

I had the idea that maybe this swapped in SAS had never been coded to his car, so I used NCS Expert to code it. After that, and cycling the ignition key, we were able to successfully reset SAS using tool32. Success!

I also updated his MS42 DME during the session.

Next up: code his swapped instrument cluster after he gets the BMW Scanner 1.4 cable.
