Case IH DCU19352: Reverting Valve (4-2way Valve?) Mechanically Faulted

The system has identified a fault related to the reverting valve, which is described as a 4-2way valve. The valve is not opening as expected, and there is an open circuit associated with the P20A0 Vent valve (Reductant Purge Control Valve).

1. 1

   The condition of the reverting valve (4-2way valve?) for mechanical obstruction or damage

2. 2

   The integrity of the circuit connected to the P20A0 Vent valve (Reductant Purge Control Valve)

3. 3

   The connection and wiring of the P20A0 Vent valve (Reductant Purge Control Valve)

1. 1

   Inspect the reverting valve (4-2way valve?) for mechanical issues

   Check for any physical damage, blockage, or misalignment that may prevent the valve from opening.

2. 2

   Test the circuit of the P20A0 Vent valve (Reductant Purge Control Valve)

   Use a multimeter to check for continuity and ensure there is no open circuit in the wiring.

3. 3

   Verify the wiring and connections of the P20A0 Vent valve (Reductant Purge Control Valve)

   Ensure all connections are secure and free from corrosion or damage.
