(1) Wiper mist
When the multifunction switch is pushed to the MIST position for 0.1 sec. or more with the IGN1 ON,
the wiper relay is turned on after 0.1 sec. has passed. When the wiper returns to the park position, the
wiper relay is turned off.
When the MIST switch signal is input the wiper is operated at high speed. When the switch is release
from the MIST position, the wiper is operated at low speed. 1.

(2) Wiper LO/HI control
The wiper LOW relay is turned on when the multifunction wiper switch is at the LO position. The wiper
HIGH relay is turned on when the wiper switch is at the HI position. When the wiper switch is at the HI
position, both the LOW relay (constant operation) and HIGH relay are operated.
The wiper motor returns to parking position and stops, even when turning off the ignition switch during
wiper operation.
The wiper relay should stay ON in low/high wiper operation mode even if the parking signal for the
wiper motor is not received. In INT/AUTO wiper operation mode, the wiper relay should be turned
OFF after 5 seconds if there is no parking signal for the wiper for 3 seconds and informs the driver of
parking position signal abnormality.
While the wiper operates at low/high speed, the front/rear washer switch can be operated but the auto
washer switch cannot.
The wiper motor returns to parking position and stops when turning off the ignition switch during wiper
operation in high mode. 1.

When holding the front washer switch at ON position for 0.1 to 0.59 seconds during the wiper
operation by the intermittent/automatic wiper switch, the wiper will operate only once. When holding
the washer switch for more than 0.6 seconds, the wiper relay is activated 0.5 seconds after. The
wiper stops after three more wipes since that the washer switch is turned to "OFF" position. 2.

When the washer switch signal is received during intermittent operation coupled with rain sensor
with IGN ON and intermittent/automatic
washer switch operation, the wipers operate in washer coupled mode regardless of the
communication with the rain sensor. However, if the washer switch
signal is received the washer relay is activated and wiper relay remains activated,
when the data coupled with rain sensor indicates continuous wiper operation.
Even though the wiping system is in washer coupled wiper mode, the operating data are sent to
rain sensor. 1.

Hydraulic power steering Electric power steering
1. OVERVIEW
The electric power steering, EPS, does not have any belt-driven steering pump constantly running, so it
is lightweight and the motor consumes energy only when the steering wheel is turned by the driver, and
this leads to improvement in fuel efficiency. Also, the elimination of a belt-driven pump and its
accessories greatly simplifies manufacturing and maintenance. While offering these benefits, as it does
not contain any steering oil, the environment is not polluted both when the steering system is produced
and discarded.
In other words, the electric power steering (EPS) system uses the electric motor to assist the steering
force. It functions independently regardless of whether the engine is running or not, unlike the existing
hydraulic power steering.
The EPS system generates an assist steering force variably depending on the driving conditions by
controlling the motor's operation, based on the input signals from the sensors such as torque sensor and
angle sensor. In turn, the EPS receives the torque signal by the driver's movements of the steering
wheel, as well as the vehicle speed, and uses the motor to determine the assist torque. The EPS
controls the motor for this. Another features of EPS are fail-safe function, diagnosis function,
communication function between units and interface function for external diagnostic device.
The EPS system components such as the torque sensor, steering angle sensor, fail-safe relay, etc. are
located in the steering column and EPS unit assembly.
Advantages: ▶
Assurance of improved steering
Provides optimal steering force according to the
vehicle speed
Enhanced steering stability while driving at high
speed (1)
-
-Reduced fuel consumption
Consumes energy only when steering wheel
is turned (improved by 3 to 5%)
Energy saving (reduced by 85% compared
with hydraulic power steering)
Reduced number of parts: Elimination of
steering pump, hydraulic hose, pump pulley,
oil reservoir, belt, bracket, etc. (2)
