Case IH 2612 (6153.01) - DEC – DEC: Synchro 2/4 plausibility check - Data Valid But Below Normal Operational Range - Most Severe Level

The system is detecting an anomaly or out-of-range reading regarding the transmission synchronizer responsible for engaging gears 2 and 4. The controller is likely seeing sensor data (such as synchronizer position or speed matching) that does not make logical sense for the commanded gear state.

• MAXXUM T4E

1. 1

   Inspect the Synchronizer 2/4 assembly (Synchro ring/hub)

2. 2

   Inspect the Transmission position/speed sensors

3. 3

   Inspect the Transmission control solenoids/valves
