Service Stability Message Displayed, DTC C0550 Set (Reprogram EBCM)

This bulletin is being revised to correct the Subject line. Please discard Corporate Bulletin Number 04-08-49-006B (Section 08 -- Body and Accessories).

Some customers may comment that while driving downhill and making a turn, the Service Stability message will display in the Driver Information Center (DIC). This will occur prior to ABS activation and once stopped, the message will go off. Upon investigation, the technician may find DTC C0550 stored in history.

The cause of this condition may be that the "Long Accel Gain" parameters in the EBCM are sensitive to certain driving conditions.

Technicians are to reprogram the EBCM with an updated software calibration. This new service calibration was released with TIS satellite data update version 9.5 available September 20, 2004. As always, make sure your TECH 2® is updated with the latest software version.
