1. 1

   Determine if the code is a Pending Code (early warning) or a Permanent Code (confirmed fault requiring repair).

2. 2

   Check the machine's display (such as the AFS Pro display) or use a diagnostic platform like Jaltest to view freeze-frame data for exact conditions and voltage readings at the time of the fault.

3. 3

   Inspect the wiring harness leading to the electro-hydraulic backup braking pressure sensor for an open circuit or a short to a positive voltage source (+V).

1. 1

   Repair wiring

   Perform a wiring repair to fix the open or shorted circuit.

2. 2

   Replace sensor

   Perform a direct replacement of the failed sensor if the wiring cannot be repaired or is intact.
