Verify that the Fan Drive is ON
The fan drive may be turned ON or the fan drive may be turned OFF through the Electronic Technician (ET). When the Fan drive is ON, the fan drive is in a variable speed mode. When the fan drive is OFF, the fan drive is in the locked up mode.
Locking up the fan drive can verify that the fan drive is mechanically sound and hydraulically sound. In order to change the mode of the fan drive, use ET and the procedure that follows:
- After connecting with ET, select the engine ECM.
