Mack CHU613 986 SPN Fault Code

Name:

Engine Fan 1 Requested Percent Speed

Description:

Fan speed of the first or only fan in the system as a ratio of the actual fan drive (current speed) to the fully engaged fan drive (maximum fan speed). A two state fan (off/on) will use 0% and 100% respectively. A three state fan (off/intermediate/on) will use 0%, 50% and 100% respectively. A variable speed fan will use 0% to 100%. Multiple fan systems will use 0 to 100% to indicate the percent cooling capacity being provided. Feedback to this request is provided using the estimated fan speed (see SPN 975).Note that the intermediate fan speed of a three state fan will vary with different fan drives, therefore 50% is being used to indicate that the intermediate speed is required from the fan drive. Typically, the first fan in a system will be the fan closest to the radiator. The second fan will be located farthest from the radiator. See SPN 6730 for systems that have two fans.
