Cummins ISX12 CM2250 (2010-12) Fault Code: 319 ...

Circuit DescriptionUnder ordinary operating conditions, the real-time clock in the Electronic Control Module (ECM) is powered by the vehicle’s batteries. If battery power to the ECM is lost, then the...

Cummins ISX12 CM2250 (2010-12) Fault Code: 3186...

Circuit DescriptionNormally, switches, accelerators, and other components are connected to the engine electronic control module (ECM) directly through individual wires. Multiplexing allows those same components to be hard wired to...

Cummins ISX12 CM2250 (2010-12) Fault Code: 3168...

Circuit DescriptionThe ECM calculates an aftertreatment diesel particulate filter flow resistance, using the aftertreatment diesel particulate filter differential pressure and calculated exhaust flow rate. Component LocationThe aftertreatment diesel particulate filter...

Cummins ISX12 CM2250 (2010-12) Fault Code: 3167...

Circuit DescriptionThe aftertreatment fuel injector is electronically controlled by the engine electronic control module (ECM) through a pulse width modulated (PWM) signal. The amount of fuel injected is determined by...

Cummins ISX12 CM2250 (2010-12) Fault Code: 3165...

Circuit DescriptionThe selective catalytic reduction (SCR) outlet temperature sensor is used by the engine control module (ECM) to monitor the engine exhaust temperature exiting the SCR catalyst. The ECM monitors...

Cummins ISX12 CM2250 (2010-12) Fault Code: 3164...

Circuit DescriptionThe SCR intake temperature sensor is used by the engine control module (ECM) to monitor the engine exhaust temperature entering the SCR catalyst. The ECM monitors the voltage on...
