2.2.330. SPN 520359, FMI 31, Pressure Control Valve: Open circuitΒΆ

Description

The EEM monitoring system has detected an open load on the pressure control valve output.

Possible causes are:

  • The pressure control valve wiring is defective (open load).
  • The pressure control valve is defective.
  • The pressure control valve is missing.

Reaction in EEM

The FC is stored and the warning lamp is activated. The CAN message indicates an active fault.

Solution

First save the error log and then do the procedure that follows:

  • Examine the pressure control valve wiring, the connectors and the contact surfaces of the connector pins (possible oxidation).
  • Test the operation with another pressure control valve to see if valve is defective.
