Cummins ISB4.5 CM2150 Fault Code: 257 PID: SID 17 SPN: 632 FMI: 7 Engine Fuel Shutoff Valve Driver – Mechanical System Not Responding Properly or Out of Adjustment.
Posted by Diezel Solutions on
Circuit DescriptionVoltage is supplied to the fuel shutoff valve by the electronic control module (ECM) while the engine keyswitch is ON. While the keyswitch is turned OFF, the voltage to the fuel shutoff valve is turned off by the ECM. The fuel shutoff valve closes and stops fuel from flowing to the fuel system. Component LocationThe fuel shutoff valve is located near the fuel pump. Conditions for Running the DiagnosticsThis diagnostic runs immediately after the keyswitch is turned to the OFF position. Conditions for Setting the Fault CodesEngine speed is greater than a calibratable value after the keyswitch is turned...
Cummins ISB4.5 CM2150 Fault Code: 2634 PID: SPN: 641 FMI: 12 VGT Actuator Controller – Bad Intelligent Device or Component.
Posted by Diezel Solutions on
Circuit DescriptionThe variable geometry turbocharger (VGT) is electronically activated by the VGT actuator. The VGT actuator is a smart device that receives information via the J1939 data link from the primary engine electronic control module (ECM). The VGT actuator performs its own diagnostics and reports errors back to the primary engine ECM using the J1939 data link. Component LocationThe VGT actuator is located on the turbocharger bearing housing. Conditions for Running the DiagnosticsThis diagnostic runs continuously when the keyswitch is in the ON position or when the engine is running. Conditions for Setting the Fault CodesThe VGT actuator has detected...

Cummins ISB4.5 CM2150 Fault Code: 269 PID: SPN: 1195 FMI: 2 Antitheft Password Valid Indicator – Data Erratic, Intermittent, or Incorrect.
Posted by Diezel Solutions on
Circuit DescriptionThe immobilizer antitheft device is connected to the primary engine electronic control module (ECM) through a J1939 data link network. Messages sent from the immobilizer antitheft device are received by the ECM and used for controlling the antitheft features. The ECM and immobilizer antitheft device must be configured properly so that proper operation of the multiplexed components will occur. Component LocationThe J1939 data link wiring and location of original equipment manufacturer (OEM) installed J1939 devices varies by OEM. The immobilizer antitheft device is installed by the OEM. Conditions for Running the DiagnosticsThis diagnostic runs continuously when the keyswitch is...
