Well, so much for dealer know-how. This is what's in the repair manual. Cut & paste doesn't format perfectly, sorry.
FYI, P17A2 = "clutch slip detected"

DESCRIPTION AND OPERATION > MANUAL TRANSMISSION PROTECTION
DESCRIPTION AND OPERATION
The engine control module (ECM) software provides protection features for the clutch and manual
transmission. The ECM uses various inputs to monitor clutch use and performance and transmission
temperature. ECM inputs include:
Clutch Pedal Position
Engine Speed
Engine Torque
Transmission Temperature (if equipped with transmission fluid temperature sensor)
Vehicle Speed
These features are designed to protect the clutch and transmission from driver misuse and high thermal
stresses. The ECM can provide the driver feedback through the driver information center (DIC) in an
effort to protect these transmission components from premature wear and failure.

DESCRIPTION AND OPERATION > MANUAL TRANSMISSION PROTECTION
DESCRIPTION AND OPERATION > CLUTCH MISUSE
Using the inputs, the ECM can detect driver clutch misuse. If the clutch pedal is partially applied for an
extended period of time, while the vehicle is being driven, a message on the DIC will be displayed to
alert the driver to release the clutch pedal.

DESCRIPTION AND OPERATION > MANUAL TRANSMISSION PROTECTION
DESCRIPTION AND OPERATION > CLUTCH SLIP
Using the inputs, the ECM can detect if the clutch is slipping under various conditions.
After a gear shift, with the clutch pedal released, and the engine under load; if the measured gear
ratio is excessively higher than the highest transmission gear ratio; the ECM will momentarily
reduce engine torque in an effort to reduce clutch slippage.
If the gear state changes, without the use of the clutch, while the engine is under load; the ECM will
momentarily reduce engine torque in an effort to reduce clutch slippage.
Driving with the clutch pedal fully released, and the engine under load; if the measured gear ratio is
excessively higher than the current transmission gear ratio; the ECM will momentarily reduce
engine torque in an effort to reduce clutch slippage. Additionally, if excessive clutch slip events
occur, the ECM may set DTC P17A2.
