66 RENR5042-02 Troubleshooting Section Possible Performance Effect: i02290633 CID 0111 FMI 02 Engine Coolant Level Sensor Loss of Signal None Troubleshooting: Perform the following diagnostic procedure: “Engine Temperature Sensor Open or Short Circuit - Test” SMCS Code: 5574-038-CLT Results: Conditions Which Generate This Code: OK STOP. The signal from the coolant level sensor is missing. System Response: i02214871 CID 0110 FMI 04 Engine Coolant Temperature short to ground The Electronic Control Module (ECM) will log the diagnostic code. The diagnostic code may be viewed on a display module or on the electronic service tool. Troubleshooting: SMCS Code:
1906-038 Perform the following diagnostic procedure: “Coolant Level Sensor Circuit - Test” Conditions Which Generate This Code: The Electronic Control Module (ECM) detects the following conditions: Results: OK STOP. The engine has been running for more than seven minutes. i02281079 CID 0168 FMI 00 System Voltage High The signal voltage from the engine coolant temperature sensor is less than 0.2 VDC for more than eight seconds. System Response: SMCS Code: 1401-038 The ECM will log the diagnostic code. The check engine lamp will illuminate after a delay. Conditions Which Generate This Code: The Electronic Control Module (ECM) has been powered for at least three seconds.
The ECM detects the following condition: The ECM will set the value of the coolant temperature to a default value. The engine will not go into cold mode while the diagnostic code is active. For 12 volt systems, the ECM reads battery voltage that is above 16 VDC. The ECM will activate the cooling fan after this code has been active for more than eight seconds. For 24 Volt systems, the ECM reads battery voltage that is above 32 VDC. Note: Excessive voltage to the ECM may damage the ECM. Troubleshooting: Perform the following diagnostic procedure: “Engine Temperature Sensor Open or Short Circuit - Test” System Response: Results: The ECM will log the diagnostic code. OK STOP.
Possible Performance Effect: None
