Cummins ISB4.5 CM2150 Fault Code: 1962 PID: SID 27 SPN: 641 FMI: 0 VGT Actuator Driver Over Temperature (Calculated) – Data Valid but Above Normal Operating Range – Least Severe Level.
Circuit Description
The variable geometry turbocharger (VGT) is electronically activated by the VGT actuator. The VGT actuator is a smart device and receives information via the J1939 data link from the primary engine engine control module (ECM). The VGT actuator performs its own diagnostics and reports malfunctions back to the primary engine ECM using the J1939 data link.
Component Location
The VGT actuator is located on the turbocharger bearing housing.
Conditions for Running the Diagnostics
The diagnostic runs continuously when the keyswitch is turned on.
Conditions for Setting the Fault Codes
The fault code will log when the internal temperature of the VGT actuator exceeds 125°C [257°F] continuously for 30 minutes.
Action Taken When the Fault Code is Active
-The ECM illuminates the amber CHECK ENGINE light immediately when the diagnostic runs and fails.
Conditions for Clearing the Fault Code
The ECM will turn off the amber CHECK ENGINE light immediately after the internal actuator temperature drops below 125°C [257°F].
Shop Talk
This fault code will be inactive when the vehicle is in the shop because the VGT actuator temperature has cooled down. Troubleshoot multiple inactive counts of this fault code as an active fault code.
Also check for exhaust leaks blowing on the VGT actuator. Repair any external leaks.
