Case IH 4195 – DU Module: Rear EHR no.2 motor mode switch faulty (DU module only)

This code indicates a malfunction in the motor mode switch for the #2 rear Electronic Hydraulic Remote (EHR). The system has detected an invalid signal, open circuit, or short circuit from the switch that controls the continuous flow/motor mode for the second rear remote valve.

1. 1

   Inspect the physical condition of the #2 rear remote control lever and motor mode switch on the armrest console for physical damage, sticking, or debris.

2. 2

   Access the wiring beneath the armrest console. Inspect the electrical connector at the #2 EHR switch and trace the harness back to the DU module. Look for pinched wires, corrosion, or loose pins.

3. 3

   Look for related communication codes (e.g., 4191 - Rear remote no.2 - no communications). If communication codes are present, the issue is likely in the CAN bus harness rather than the switch itself.

4. 4

   If the design of your specific armrest allows, temporarily swap the electrical connection of the #2 EHR switch with the #1 or #3 switch. If the fault code changes to 4194 (No.1 switch) or 4196 (No.3 switch), the switch itself is confirmed faulty.

1. 1

   Power Down

   Turn off the tractor, remove the key, and disconnect the battery to prevent electrical shorts or accidental module damage.

2. 2

   Access the Console

   Remove the retaining screws and carefully lift the armrest console cover or the specific trim panel surrounding the EHR remote levers.

3. 3

   Disconnect

   Locate the #2 EHR lever assembly (often color-coded, e.g., blue or green depending on the remote number). Disconnect its electrical harness connector.

4. 4

   Remove the Switch

   Unbolt or unclip the faulty EHR lever/motor mode switch assembly from the console bracket.

5. 5

   Install the New Part

   Seat the new EHR lever assembly into the bracket and secure it.

6. 6

   Reconnect

   Plug the electrical harness into the new switch, ensuring the locking tab clicks into place.

7. 7

   Reassemble

   Reinstall the armrest console cover and trim panels.

8. 8

   Clear Codes & Test

   Reconnect the battery and power on the tractor. Use the tractor's diagnostic display or an Electronic Service Tool (EST) to clear the inactive 4195 fault code. Test the #2 rear remote in motor mode to verify proper operation.
