Steering System
Electronic Steering Control Unit
51663
Each engine uses a hydraulic valve body and a steer-
ing control unit to control the movement of the drive
during steering. Both devices are contained in a black
housing
A
mounted somewhere in the engine com-
partment.
When you first turn the ignition key to START (key on,
engine off), you may hear clicking noises coming from
the engine compartment. This is a sound that is emit-
ted by the hydraulic system when it is functioning nor-
mally.
