This diagnostic code is used only by GMT-560 applications. The ECM detects the following: •The Secondary Fuel Level signal voltage is below the acceptable range for more than 10 seconds. The fuel level sensors are OEM installed components for the vehicle. The sensors are selectable through a customer programmable parameter and the customer programmable parameter may be protected by customer passwords. Possible Causes: 1) Loose ECM Connection/Harness2) Fuel level sensor failure3) WIring between fuel level sensor & ECM CAT 3126B Fault Code: 128-03 PID: Flash Code 44 SPN: FMI: Secondary Fuel Level voltage high CAT 3126B Fault Code: 22-13 PID:...

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 3126B Fault Code: 111-04 PID: Flash Code 12 SPN: 111 FMI: 4 Coolant Level voltage low CAT 3126B Fault Code: 111-03 PID: Flash Code 12 SPN: FMI: Coolant Level voltage high CAT 3126B Fault Code: 111-02 PID: Flash Code 12 SPN: FMI: Coolant Level signal invalid CAT 3126B Fault Code: 71-0 PID: Flash Code 01 SPN: FMI: Idle Shutdown...

The customer parameter PTO configuration is programmed to remote throttle and the PTO On/Off switch is ON. The ECM is not receiving a correct PTO throttle signal CAT 3126B Fault Code: 164-3 PID: Flash Code 15 SPN: 164 FMI: 3 Injection Actuation Pressure Open Circuit CAT 3126B Fault Code: 111-04 PID: Flash Code 12 SPN: 111 FMI: 4 Coolant Level voltage low CAT 3126B Fault Code: 111-03 PID: Flash Code 12 SPN: FMI: Coolant Level voltage high CAT 3126B Fault Code: 111-02 PID: Flash Code 12 SPN: FMI: Coolant Level signal invalid CAT 3126B Fault Code: 71-0 PID: Flash Code...
