Case IH 2261 (519185.04) - DEC – DEC / ECU A-095: Synchro F Solenoid - short to GND

The electrical circuit controlling the Synchro F (Forward or F-range transmission synchronizer) solenoid has shorted to ground, bypassing the intended electrical load. Alternatively, this code may indicate battery voltage is very low or lower than expected.

1. 1

   Visually inspect the relevant transmission harnesses and connectors leading to the transmission synchronizer solenoids for chafing, melted insulation, or pinched wires.

2. 2

   If the machine is logging 2261 as a voltage error (alternative definition), perform a parasitic draw test to measure excessive current draw from the battery.

3. 3

   Check the ECU (such as A-095) for the appropriate software version and re-flash if necessary.

1. 1

   Locate shorted wire

   Locate the shorted wire in the transmission harness using a multimeter (checking for continuity to ground on the solenoid's power circuit).

2. 2

   Repair or replace wiring

   Repair or replace the damaged section of the wiring harness.

3. 3

   Replace solenoid

   If the wiring is intact, replace the internally shorted Synchro F Solenoid on the transmission valve body.
