1. 1

   Check for other active error codes related to CAN bus communication. If present, follow the troubleshooting procedures for the CAN bus first.

2. 2

   Inspect the electrical connector at the rear remote #7 EHR valve. Ensure it is securely connected, not damaged, and that the pins are tight and in the correct position.

3. 3

   Check the wiring harness between the EHR valve and the ECU for continuity, shorts to ground, or open circuits.

4. 4

   Test the EHR valve itself. If the CAN bus, harness, and connectors are all in good working order, the valve is likely faulty.

1. 1

   Resolve the underlying fault

   Based on the diagnostics above, repair or replace the damaged CAN bus wiring, faulty connector, damaged harness, or the defective EHR valve section.

2. 2

   Clear the code

   Once the physical repair is made, use the Electronic Service Tool (or tractor display) to clear the error code.

3. 3

   Test operation

   Cycle the tractor's power and test the rear remote #7 system to ensure normal operation and verify that the code does not return.
