3.2.344. SPN 520359, FMI 31, Open load of pressure control valve outputΒΆ

Description

The EEM4 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 active fault.

Solution

First save the error log and then erase it. Restart the ECU after erasing the error log. If the fault occurs again during the next driving cycle, check the following paths:

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