Replacing the TSAS ECM

SUBJECT # 16:
REPLACING THE TSAS ECM

APPLICATION:
VIN SERIAL NOS. S7000216-S7015157

Change the TSAS ECM.




Since the new ECM can generate an additional SID message, the SID and the owners manual should also be up dated.

Parts:

TSAS ECM 46 10 812
Owner's Manual Label 04 08 948

Tools:

ISAT

IMPORTANT
When these steps have been taken, it will not be possible to operate the top mechanism by means of the ROOF switch until the potentiometer resistance readings have been programmed into the new ECM.

NOTE:
The new ECM will not allow the windows to be raised while operating the top (old ECM did allow for this).
