Case IH 2113 – Transmission controller: Axle oil pressure low fault - Axle lube oil circuit

The axle lube oil pressure switch has not indicated pressure 1.5 seconds after start-up. The switch is designed to close at 0.55 bar (8 psi), and failure to do so triggers this code.

1. 1

   Inspect the wiring harness and connectors between the axle lube oil pressure sensor and the ECU.

2. 2

   Ensure the connectors are fully connected, not damaged, the pins are in the correct position, and that the fit is tight.

3. 3

   Check for continuity between the pressure sensor and the ECU to rule out an open circuit or short circuit to ground.

4. 4

   If a wiring issue is found, repair or replace the wiring as required. If the fault code is no longer present after fixing the connection, return the machine to proper operation.

1. 1

   Locate switch

   Locate the axle lube oil pressure switch on the axle housing.

2. 2

   Disconnect and inspect

   Disconnect the electrical harness from the switch and perform the visual and continuity checks mentioned above.

3. 3

   Verify switch failure

   If the wiring harness is in good condition and continuity is verified, the fault is likely a failed pressure switch that is stuck open or unable to read the 0.55 bar (8 psi) threshold.

4. 4

   Remove faulty switch

   Unthread the faulty axle lube oil pressure switch from the axle circuit.

5. 5

   Install new switch

   Install the replacement OEM pressure switch and tighten to specification.

6. 6

   Reconnect harness

   Reconnect the electrical harness.

7. 7

   Clear code and verify

   Clear the fault code using the tractor's diagnostic display (accessed via the "PROG" and up/down arrow keys on the A-post) and start the tractor to verify the code does not return after 1.5 seconds.
