Condition
Diagnostic Trouble Code (DTC) ECM-6100 is stored in the engine control module (ECM) if the engine cooling fan (FC) control module registers that the fan blades are obstructed or that there is no power supply. The diagnostic trouble code (DTC) is also stored if an internal fault in the engine cooling fan (FC) control module is registered. The diagnostic trouble code (DTC) is diagnosed when the engine is idling.
Note! The electric cooling fan may have a post-running time of up to approx. 6 minutes after the engine has been shut off. The time for the electric cooling fan's post-running depends on the engine's temperature, temperature in the engine compartment as well as the pressure level in the AC system.
