The Engine Control Module (ECM) detects the following conditions: •The injection actuation pressure is greater than 3 MPa (435 psi) for more than three seconds when the engine is off.•The difference in the actual pressure and the desired pressure is greater than 2 MPa (290 psi) for more than ten seconds with the engine running.•Actual rail pressure is between 11.0 MPa (1595.41 psi) and 17.4 MPa (2523.66 psi) for more than ten seconds.•Sensor current changes more than 0.075 Amp and rail pressure changes less than 0.5 MPa (72.5 psi) with the engine on.•The engine is not running and the ECM...

Indicates the battery circuit to the ECM has either an intermittent or low battery condition while the engine is running. If battery voltage disappears without returning, the ECM will not log this diagnostic code and the engie will shut down CAT 3126E Fault Code: 111-04 PID: Flash Code 12 SPN: 111 FMI: 4 Coolant Level voltage low CAT 3126E Fault Code: 111-03 PID: Flash Code 12 SPN: FMI: Coolant Level voltage high CAT 3126E Fault Code: 111-02 PID: Flash Code 12 SPN: FMI: Coolant Level signal invalid CAT 3126E Fault Code: 71-0 PID: Flash Code 01 SPN: FMI: Idle Shutdown...

This condition indicates that the battery circuit to the Engine Control Module (ECM) has excessive voltage while the engine is running. The ECM detects the following conditions: •For 12 V systems, the battery voltage to the ECM exceeds 16 V for more than 0.5 seconds.•For 24 V systems, the battery voltage to the ECM exceeds 32 V for more than 0.5 seconds. The ECM also detects the following conditions: •The engine control is in the ON mode.•The engine is not cranking.•The engine is running.•The ECM has been powered for at least three seconds Probable Causes: 1) Aftermarket device preventing battery...
