Customers may comment that while driving downhill and making a turn, the Service
Stability message will illuminate in the DIC. This will happen prior to ABS activation
and once stopped, the message will go off. The technician will receive a DTC C0550.
The "Long Accel Gain" parameters in the EBTCM are sensitive to certain
driving conditions. A new calibration is available to all dealers. This calibration
is available in TIS version 2.5 or higher. For stand alone TIS users, these calibrations
are available in CD #3.
