1995
Cadillac Concours
Condition
A.
Some owners may comment on an intermittent "Service Ride Control" message. An RSS DTC 44 (Lift/Dive Fault) may be set. No fault will be
found when diagnosing the system as it is a software error that occurs at power-up when the PCM and RSS module perform a communication
routine.
B.
Some owners of an ETC or STS model may comment on a harsh ride. Recalibration of an ETC as an ELD or an STS as an SLS may correct the
concern.
Instructions:
Follow Tech 1 prompts to choose either -
a.
An "ETC" or "ELD" calibration for an ETC,
or
b.
An "STS" or "SLS" calibration for an STS
Correction
In August, 1995, a new version of the Tech 1 CD is being released which contains revised software for the 1994-95 Road Sensing Suspension (RSS)
Systems. Any vehicle listed below with either of the above concerns should be recalibrated per the new EEPROM ID.
Important:
The August, 1995 Tech 1 CD will display "GM 94-96 Chassis V1.2" when the chassis option is chosen.
