Verify the 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 one of the following error conditions exists. 1)If the turbocharger actuator has just been replaced and this fault code is active, this usually indicates that the turbocharger actuator has not been installed correctly. The gear alignment between the actuator and the turbocharger housing is misaligned.2)Foreign material in the VGT turbocharger can prevent the sliding nozzle from moving to the desired position at key-on. The...
Cummins ISB6.7 CM2150 (2007-09) Fault Code: 245 PID: SID 033 SPN: 647 FMI: 4 Fan Control Circuit – Voltage Below Normal or Shorted to Low Source. Low signal voltage detected at the fan control circuit when commanded ON.

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. The fan control logic can be adjusted with INSITE™ electronic service tool. There are two choices: 12 or 24 volts ON, or 0 volts ON. For proper fan operation, the fan control logic setup with INSITE™ electronic service tool must match the hardware configuration on the vehicle. This fault code is logged when the ECM commands 12 or 24 VDC to the fan control solenoid, but the...

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. The most common cause of this fault code is low boost pressure. Low boost pressure can be caused by several factors; leaking charge air cooler, damaged charge air cooler piping or hose, loose charge air cooler clamps, damaged intake manifold pressure sensor, damaged variable geometry turbocharger, damaged turbocharger control valve, or damaged turbocharger control shutoff valve. This fault code can also be caused by a turbocharger fuel...
Cummins ISB6.7 CM2150 (2007-09) Fault Code: 249 PID: 171 SPN: 171 FMI: 3 Ambient Air Temperature Sensor 1 Circuit – Voltage Above Normal or Shorted to High Source. High signal voltage detected at ambient air temperature circuit.

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. The ambient air temperature sensor shares return wires in the engine harness with other sensors. Opens and shorts in the engine harness can cause multiple fault codes to be active. Check active fault codes with multiple counts first. Possible causes: 1)Open return circuit in the harness, connectors, or sensor2)Open signal circuit or shorted to voltage source. Possible repairs: 1)Replace the ambient air temperature sensor.2)Replace the ECM.3)Repair or...
Cummins ISB6.7 CM2150 (2007-09) Fault Code: 252 PID: 98 SPN: 98 FMI: 2 Engine Oil Level – Data Erratic, Intermittent, or Incorrect. An intermittent signal is being received from the oil level sensor.

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. Possible causes: 1)The oil level sensor is not receiving power from the ECM. This could be caused by an open circuit in the power supply or low voltage supplied by the primary engine ECM2)Open return circuit on the oil level sensor circuit between the engine ECM and the oil level sensor3)Open or short circuit on the oil level sensor signal circuit between the ECM and oil level...
