Checking the wiring and component: Notes
WARNING:
Before fault-tracing can begin, the engine cooling fan (FC) connector must be disconnected to prevent the engine cooling fan (FC) engaging. Diagnostic trouble code (DTC) ECM-6120 Engine cooling fan (FC) control module may be stored. After fault-tracing the connector must be reconnected.
Check the resistance of the engine coolant temperature (ECT) sensor.
Check the signal cable between control module terminal #A4 (#A4) and engine coolant temperature (ECT) sensor terminal #1. Check for a short-circuit to ground.
Remedy as necessary.
