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, calibrate the ECM. This fault code is logged when the electronic control module (ECM) has calculated DOC efficiency to be less than required to successfully complete a regeneration. Possible causes: 1)Soot plugging the front face of the aftertreatment diesel oxidation catalyst2)Engine oil or fuel contamination of the aftertreatment diesel oxidation catalyst3)Cracked or contaminated aftertreatment diesel oxidation catalyst4)Damage in the aftertreatment fuel injection system5)Leaking exhaust system between the turbocharger and the...
PACCAR PX-8 CM2150 (2007-09) Fault Code: 2639 PID: SID 324 SPN: 3251 FMI: 0 Aftertreatment Diesel Particulate Filter Differential Pressure – Data Valid But Above Normal Operating Range – Least Severe Level.

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. Note: This fault code indicates that the aftertreatment diesel particulate filter requires maintenance by performing a stationary regeneration procedure. This is a maintenance procedure only and is not covered by Cummins Inc. warranty. Note: Repeated occurrences of this fault code may indicate the engine requires frequent regeneration. Refer to symptom tree t147 (Aftertreatment Diesel Particulate Filter-Excessive Automatic and/or Stationary Regeneration) to identify the cause of frequent regeneration. Possible causes: 1)The engine has...
PACCAR PX-8 CM2150 (2007-09) Fault Code: 2646 PID: 110 SPN: 110 FMI: 31 Engine Coolant Temperature – Condition Exists. The EGR valve was closed to reduce engine coolant temperature.

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. When the engine coolant temperature nears the engine protection limits, the EGR valve will be closed to reduce the coolant temperature. This fault code is used as an information fault code, only indicating that the EGR valve has closed. No failure has occurred to cause this fault code. Other engine protection fault codes will be active if the engine coolant temperature has exceeded the engine protection limits....

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 becomes active when the ECM detects a short circuit in the electronic fuel control actuator circuit. Causes for this fault code are short circuit to ground or low resistance (fuel control actuator coil is shorted internally) in the circuit for the fuel pump actuator. When excessive current or a short circuit is detected, the ECM driver to the fuel control actuator is turned off to...
