Case IH 2257 (519184.17) - DEC – DEC: Synchro M Solenoid LSD short to GND

The Low Side Driver (LSD) circuit for the Synchro M Solenoid is shorted to ground, meaning the wiring or the solenoid itself is shorted directly to the chassis ground, bypassing the module's ability to control the circuit.

1. 1

   Inspect the wiring harness between the control module and the Synchro M Solenoid for chafing, pinched wires, or melted insulation that is allowing the wire to touch the machine's metal chassis (ground).

2. 2

   Test the Synchro M Solenoid for an internal short to its own casing.

3. 3

   Check the control module's pins for internal shorts.
