Case IH 5007 – CCH (Cab Controller Hub) or Rear PTO Controller: PTO remote fender switch stuck on (CCH Only)

The controller is receiving a continuous, uninterrupted 'ON' signal from the remote Power Take-Off (PTO) switch located on the rear fender. If the controller sees the 'on' state continuously without a break, it flags the switch as stuck and disables the PTO for safety.

1. 1

   Verify tractor configuration: If the tractor is not equipped with rear fender PTO switches, use the Electronic Service Tool (EST) to set 'Fender Switches' to 'No' (configuration error cause).

2. 2

   Inspect the fender switches for physical damage, packed dirt, or ice that might be physically holding the button down.

3. 3

   Disconnect the wiring harness from the fender switch. If the code changes to an open circuit code (5034 or 158), the switch itself is internally shorted or stuck.

4. 4

   If disconnecting the switch does not change the code, use a multimeter to check the wiring harness between the fender and the CCH for a short to 12V power (wiring harness cause).

5. 5

   Check the yellow PTO switch inside the cab to ensure it is not flimsy or sticking, which can cause erratic controller behavior and related PTO codes.

1. 1

   Power Down

   Turn off the tractor, remove the key, and locate the affected PTO remote switch on the rear fender.

2. 2

   Clean the Area

   Thoroughly clean the mudguard/fender area around the switch to prevent dirt from falling into the electrical connectors.

3. 3

   Disconnect

   Reach behind the fender panel and unplug the electrical harness connector from the back of the switch.

4. 4

   Remove the Switch

   Depress the retaining clips or remove the retaining nut holding the switch into the fender casting, and push the switch out of its mounting hole.

5. 5

   Install the New Part

   Snap or thread the new OEM switch into the fender housing until it is secure.

6. 6

   Reconnect

   Plug the electrical harness back into the switch. Ensure the weather-pack seal clicks firmly into place.

7. 7

   Test

   Start the tractor. The 5007 code should move from 'Active' to 'Inactive' (or clear entirely), and normal PTO operation should be restored.
