Faulty Signal. Intermittent Fault






Faulty signal. Intermittent fault

Checking wiring and connectors

Warning! Before fault-tracing can begin, the engine cooling fan (FC) relay connector must be disconnected to prevent the engine cooling fan (FC) engaging. Diagnostic trouble code (DTC) ECM-6110 Engine cooling fan (FC) low-speed signal may be stored. After fault-tracing the connector must be reconnected.

Note! This diagnostic trouble code (DTC) is stored if the engine coolant temperature (ECT) sensor freezes. This may happen if the coolant level is low or there is too little glycol in the coolant. Check the engine coolant level and its freezing point. Remedy as necessary.

Check the engine coolant temperature (ECT) sensor connector. Check for contact resistance and oxidation. See Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults. Check for loose connections. See Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.

Hint: The fault may have been caused by air pockets in the cooling system.

Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).
