Summary of the Safety Concern:
VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH HORTON FAN DRIVES. THE FAN DRIVE CONTROL SYSTEM WAS RECONFIGURED WHICH RESULTED IN A SIGNIFICANT INCREASE IN THE DEMAND FOR FAN ACTIVATION AND ASSOCIATED STRESS TO ELECTRICAL AND MECHANICAL COMPONENTS.

Consequence:
IF THE FAN IS LOCKED, THE THE SYSTEM CALLS FOR THE FAN TO BE ON, THE FAN CLUTCH WILL SLIP, GENERATE HEAT, AND UNLESS RELEASED, WILL RESULT IN A FIRE. |
