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.
1)Replace the engine brake solenoid.
2)Replace the ECM.
3)Repair or replace the engine harness.
PACCAR PX-6 CM2150 (2007-09) Fault Code: 1993 PID: SPN: 3064 FMI: 11 Aftertreatment Particulate Trap Missing – Condition Exists. The aftertreatment diesel particulate filter in the exhaust system is not present.
PACCAR PX-6 CM2150 (2007-09) Fault Code: 1981 PID: SID 324 SPN: 3926 FMI: 0 Aftertreatment Particulate Filter Differential Pressure – Data Valid but Above Normal Operational Range – Least Severe Level. The aftertreatment differential pressure has exceeded the maximum operating limits or the diesel particulate filter is plugged.
