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)A faulty transmission shift modulator2)An short circuit to ground on the output device driver line3)A short pin-to-pin in the output device driver line. Possible repairs: 1)Replace the transmission shift modulator.2)Repair or replace the OEM harness.3)Replace the ECM.
Cummins ISB6.7 CM2150 (2007-09) Fault Code: 256 PID: 171 SPN: 171 FMI: 4 Ambient Air Temperature Sensor 1 Circuit – Voltage Below Normal or Shorted to Low Source. Low signal voltage detected at the 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 fault codes with multiple counts first. Possible causes: 1)Signal circuit shorted to ground in the harness2)Signal circuit shorted to return or ground in the sensor. Possible repairs: 1)Replace the ambient air temperature sensor.2)Repair or replace the...
Cummins ISB6.7 CM2150 (2007-09) Fault Code: 2634 PID: SID 027 SPN: 641 FMI: 12 VGT Actuator Controller – Bad Intelligent Device or Component. An internal error has been detected by the smart VGT controller.

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 VGT smart actuator detected an internal error within the VGT actuator. The VGT actuator will stop controlling the turbocharger when this fault code is active. Fault Code 2634 will become active if the VGT actuator is removed from the turbocharger and then the keyswitch is turned to the on position or it may be possible for it to become active...
Cummins ISB6.7 CM2150 (2007-09) Fault Code: 2635 PID: SID 027 SPN: 641 FMI: 11 VGT Actuator Driver Circuit – Condition Exists. A calibration mismatch between the VGT actuator 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, calibrate the ECM again. This fault code is logged when the primary engine ECM does not receive valid J1939 information from the VGT actuator. Troubleshoot high inactive counts of Fault Code 2636 as an active fault code. Possible causes: 1)The VGT actuator is not receiving power from the ECM. This could be caused by an open circuit in the power supply wire or low voltage supplied by the primary engine...
Cummins ISB6.7 CM2150 (2007-09) Fault Code: 2636 PID: SID 027 SPN: 641 FMI: 9 VGT Actuator Driver Circuit – Abnormal Update Rate. No communications on the J1939 data link between the engine ECM and the smart VGT controller.
