Cummins ISL CM850 (2003-06) Fault Code: 2384 (ISL) PID: SID 27 SPN: 641 FMI: 4 VGT actuator driver circuit – voltage below normal, or shorted to low source.
Cummins ISL CM850 (2003-06) Fault Code: 2384 (ISL) PID: SID 27 SPN: 641 FMI: 4 VGT actuator driver circuit – voltage below normal, or shorted to low source.
A possible cause of this fault is the turbocharger actuator signal (+ or -) leads can be shorted to ground in the harness, motor, or the ECM.
Do not supply voltage of any kind to the exhaust gas recirculation (EGR) valve motor. This circuit uses a pulse-width-modulated signal and direct voltage can permanently damage the motor.
Possible repairs:
1)Replace the turbocharger.
2)Repair or replace the engine harness.
3)Replace the ECM.
4)The removal and reinstallation of the connector may correct the fault.
