Case IH 523275 - 03 - CSM – CSM: Cab suspension right position - cab suspension right position high

Indicates an issue with the right-hand position sensor of the cab's active suspension system. The sensor is sending a signal to the controller that is higher than the expected operating range, which could be caused by a short to power, an open ground circuit, a faulty sensor, or the suspension physically overextending.

1. 1

   Inspect the right-hand cab suspension shock absorber/actuator and the physical position sensor linkage for damage, disconnection, or physical overextension

2. 2

   Inspect the wiring harness leading to the right cab suspension position sensor for chafing, pinched wires, or corrosion at the connector

3. 3

   Test the sensor circuit for a short to power or an open ground, which typically causes a 'high' voltage reading

1. 1

   Disconnect power

   Disconnect the battery or power to the CSM before servicing electrical components.

2. 2

   Repair wiring harness

   If the wiring harness is damaged, repair the broken/shorted wires and replace the connector if necessary.

3. 3

   Replace sensor

   If the sensor is internally shorted, remove the mounting hardware for the right-hand cab suspension position sensor and install a new sensor.

4. 4

   Restore power

   Reconnect the harness and restore power.

5. 5

   Calibrate sensor

   After replacing a suspension position sensor, the Cab Suspension Module (CSM) will likely require a software calibration routine via the tractor's display or a dealer diagnostic tool to relearn the minimum and maximum travel limits.
