PACCAR PX-8 CM2150 (2007-09) Fault Code: 2198 PID: SID 027 SPN: 641 FMI: 11 VGT Actuator Driver Circuit – Root Cause Not Known. Intermittent communication between the smart VGT controller and the ECM has been detected.
Verify the electronic control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe® Online for applicable fixes to the calibration stored in the ECM. If necessary, recalibrate the ECM.
This fault code is logged when the VGT smart actuator did not receive a valid J1939 message from the primary engine ECM for 1 second. Intermittent J1939 datalink connections or interference on the J1939 network are possible causes of this fault code. Also check for intermittent power supply and ground connections to the VGT actuator.
Possible repairs:
1)Replace the VGT actuator.
