Case IH 523357 - 02 - CSM – CSM: Cab suspension controller memory error

The fault code indicates a memory or internal processing failure within the Cab Suspension Controller (CSM). FMI 02 designates erratic, intermittent, or incorrect data.

• MAGNUM AFS Connect

1. 1

   Connect the dealer Electronic Diagnostic Tool (EDT) to verify if the module is communicating on the CAN bus.

2. 2

   Attempt to run the 'Cab suspension calibration' via the EDT.

3. 3

   Verify the inputs from the cab suspension position sensor during calibration to ensure the memory error isn't being triggered by corrupted incoming sensor data.

1. 1

   Cycle Power / Reset

   Switch OFF the ignition for at least 8 seconds in order to validate the calibration after any software reset or calibration attempt.

2. 2

   Module Replacement

   If the EDT cannot clear the memory error or the module fails to hold its calibration parameters, the internal memory of the CSM has failed and the physical Cab Suspension Controller must be replaced.

3. 3

   Post-Repair Calibration

   After installing a new CSM, use the EDT to perform the Cab Suspension Calibration so the new module can learn the suspension position sensor limits.
