1. 1

   Clear the error code from the system memory and cycle the ignition to check for a temporary glitch caused by electromagnetic interference.

2. 2

   Check the sources of energy to the CSM, including fuses, power supply lines, and ground connections.

3. 3

   Check the connectors and continuity of the harnesses linking the CSM to the tractor's CAN bus system to rule out short-circuits or open circuits.

4. 4

   Check if a software update or reflash is available for the CSM to correct the memory corruption.
