3.2.478. SPN 661, FMI 14, Engine injector cylinder #11, Short circuitΒΆ

Description

The EEM4 system has detected a short circuit on the solenoid valve #11 control. Possible causes are:

  • The solenoid valve connector is defective.
  • The solenoid valve wiring is defective.
  • The solenoid valve is defective.

Reaction in EEM

The FC is stored and the warning lamp is activated. The CAN message indicates active fault. Engine power will be heavily reduced (Degradation Level 3).

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 solenoid valve 11 wiring, the connectors and the contact surfaces of the connector pins (possible oxidation).
  • Measure the cables from the solenoid valve 11 to the engine ground, to see if there is a short circuit to ground.
  • Check the operation with another engine injector to see if the engine injector is defective.
