1. 1

   Use the Case IH Electronic Service Tool (EST) to monitor the live internal supply voltage reading of the CSM

2. 2

   Verify if the voltage spike is continuous or intermittent before replacing parts

1. 1

   Test pin voltages

   Access the Cab Suspension Module (CSM) to test the physical pin voltages against the software readings.

2. 2

   Flash or replace module

   Potentially flash or replace the module if the internal voltage regulator has failed.
