3.2.433. SPN 5372, FMI 16, WG Actuator 1 temperature warning (ERROR 2)ΒΆ

Description

The WG 1 actuator temperature is too high.

Possible causes are:

  • The WG 1 actuator control shaft is defective.
  • The WG 1 actuator is defective.
  • The WG 1 actuator water cooling pipes are defective, if assembled.

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 WG 1 actuator assembly to detect the defective control shaft.
  • Check the WG 1 actuator wiring, the connectors and the contact surfaces of the connector pins (possible oxidation).
  • Check that the WG 1 actuator cooling pipes are not squashed or blocked, if assembled.
  • Check the operation with another WG actuator to see if the actuator is defective.
