62 RENR5042-02 Troubleshooting Section System Response: i02257985 CID 0041 FMI 04 8 Volt DC Supply short to ground The ECM will log the diagnostic code. The ECM will continue to attempt to operate the injector after the code has been logged. The injector may not operate while the condition exists. SMCS Code: 5574-038 Conditions Which Generate This Code: Possible Performance Effect: The output voltage of the 8 volt supply falls below 7.5 VDC for at least two seconds. Engine misfires Low power System Response: Perform the following diagnostic procedure: “Injector Solenoid Circuit - Test” The Electronic Control Module (ECM) will log the diagnostic code.
The diagnostic code may be viewed on a display module or on Caterpillar Electronic Technician (ET). The ECM flags all digital sensors as invalid data and all digital sensors are set to the respective default values. Results: OK STOP. Possible Performance Effect: i02257966 CID 0041 FMI 03 8 Volt DC Supply short to +batt Low power Troubleshooting: SMCS Code: 5574-038 Perform the following diagnostic procedure: “Digital Sensor Supply Circuit - Test” Conditions Which Generate This Code: Results: The output voltage of the 8 volt supply exceeds 8.5 VDC for at least two seconds. OK STOP. System Response:
i02258022 CID 0091 FMI 08 Throttle Position signal abnormal The Electronic Control Module (ECM) will log the diagnostic code. The diagnostic code may be viewed on a display module or on Caterpillar Electronic Technician (ET). The ECM flags all digital sensors as invalid data and all digital sensors are set to the respective default values. SMCS Code: 1913-038 Conditions Which Generate This Code: Possible Performance Effect: The frequency of the signal from the throttle that is connected to the primary throttle input is incorrect. Low power Troubleshooting: System Response: Perform the following diagnostic procedure:
“Digital Sensor Supply Circuit - Test” The Electronic Control Module (ECM) will log the diagnostic code. The ECM flags the throttle position as invalid data and a default value of zero percent is used. Results: OK STOP. Possible Performance Effect: The engine speed is limited to low idle.
