Case IH 15967 - 02 - CSM – CSM: Cab suspension damping parameter - cab suspension damping parameter memory error.

This indicates an internal memory or calibration fault within the module that controls the active/semi-active cab suspension. The module has lost or corrupted the stored parameters required to properly calculate and apply the correct damping force to the cab suspension shocks/actuators.

1. 1

   Check Module Power and Ground: Verify that the wiring harness supplying power and ground to the CSM is secure and free of corrosion. Voltage drops can cause memory retention issues in control modules.

2. 2

   Verify Software Version: Check the current software version of the CSM using the Case IH Electronic Service Tool (EST).

3. 3

   Attempt Recalibration: Attempt to run the cab suspension calibration procedure via the EST or the tractor's AFS Pro display to see if the module will accept and store new damping parameters.

1. 1

   Connect diagnostic tool

   Connect the Case IH Electronic Service Tool (EST) to the tractor's diagnostic port.

2. 2

   Navigate to module

   Navigate to the Cab Suspension Module (CSM).

3. 3

   Clear and re-flash

   Attempt to clear the fault code and re-flash the module with the latest software version.

4. 4

   Calibrate suspension

   Perform the cab suspension calibration routine.

5. 5

   Cycle key power

   Cycle the key power. If the fault code 15967 - 02 returns immediately upon key-on, the internal memory of the CSM is permanently failed.

6. 6

   Replace and program module

   Replace the Cab Suspension Module (CSM) and program the new module using the EST.
