K69 Transfer Case Control Module: Scan Tool Information
WARNING: This page is about a different car, the 2020 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.
The Transfer Case Shift Control Module Scan Tool Data List contains all transfer case related parameters that are available on the scan tool. The list is arranged in alphabetical order. A given parameter may appear in any one of the data lists, and in some cases may appear more than once, or in more than one data list in order to group certain related parameters together.
The values below represent a typical display recorded from a properly functioning system.
NOTE:
Do not use a scan tool that displays faulty data. Report the condition to the scan tool manufacturer. The use of a faulty scan tool can result in misdiagnosis and the unnecessary replacement of parts.
Only the parameters listed below are used/referenced in this manual for diagnosis. If a scan tool displays other parameters, those values are not recommended by General Motors for use in diagnosis.
The scan tool values from a properly functioning transfer case may be used for comparison with the transfer case you are diagnosing. The values below represent a typical display recorded from a properly functioning system.

Scan Tool Output Controls
| Output Control | Description |
|---|---|
| Refer to the scan tool manual for complete scan tool operating instructions. | |
| Transfer Case Clutch Engagement | This device control is intended for use on an all wheel drive system to activate the clutch control solenoid. Both the low side and high side of the clutch solenoid are controlled together. Commanding the clutch solenoid to "on" will modulate the high side driver to a calibrated "maximum" duty cycle. |
| Transfer Case Clutch Identifier | This device control is used to program the transfer case clutch identifier. |
| Transfer Case Clutch Overtemperature Counter Reset | This device control is used to reset the transfer case clutch overtemperature event counter. |
