1. SYSTEM DESCRIPTION
1) System Description
The cruise control is an automatic speed control system that maintains a desired driving speed
without using the accelerator pedal.
The vehicle speed must be greater than 38 km/h to engage the cruise control. This feature is
especially useful for motorway driving.
The cruise control system is a supplementary system, which helps the driver to drive the vehicle
at a desired speed without using the accelerator pedal under the traffic condition where the
vehicle-to-vehicle distance meets the legal requirement.

2. CONFIGURATION
1) Circuit Diagram
The engine ECU detects the operating conditions of cruise control system, and monitors the
braking performance, vehicle speed, road conditions and ESP system operation. If the engine
ECU determines that there are not any problem to drive in cruise control mode, the vehicle can be
operated by cruise switch signals (decelerating, accelerating, cruising).

5) Normal Cancellation of the Cruise Control
The cruise control system will be canceled when one or more items of the following conditions
are applied;
When the brake pedal is depressed or When ESP is activated.
When the cruising speed is downed less than 34 km/h
When applying the parking brake during driving.
When using the clutch in order to shift (M/T only). 1.

3) Operating Process by Power Supply of ICM Box
(1) Door lock relay
The power supplied through the No. F53 interior fuse on the left-hand of the engine compartment
is on standby on the No. 86 and 87 door lock relay terminals and No. 86 and 87 door unlock relay
terminals via the ICM No. 12 terminal. The STICS activates and/or controls the door lock relay
connected to the ICM No. 15 terminal using the STICS No. B3 terminal depending on the
operating conditions. The activated door lock relay supplies the No. 30 terminal with the B+
power, which is standby on the No. 87 terminal and supplies each door actuator with the B+
power.
The supplied power flows to the G201 ground connected to the ICM No. 14 terminal via the No.
30 and 87a door unlock relays for corresponding load.

(2) Door unlock relay
The supply power is on standby in the same way as the door lock relay, and the STICS activates
and/or controls the door unlock relay connected to the ICM No. 6 terminal using the STICS No.
A1 terminal depending on the operating conditions. The activated door unlock relay supplies the
No. 30 terminal with the B+ power, which is standby on the No. 87 terminal and supplies each
door actuator with the B+ power.
The supplied power flows to the G201 ground connected to the ICM No. 14 terminal via the No.
30 and 87a door lock relays for corresponding load.

(3) Turn signal lamp (Hazard warning lamp operation)
The B+ power supplied through the No. F66 interior fuse on the right-hand of the engine
compartment is on standby on the No. 30 and 86 hazard warning lamp relay terminals via the ICM
No. 18 terminal.
The STICS activates and/or controls the hazard warning lamp relay using the No. A26 terminal
depending on the operating conditions. The activated relay supplies the No. 87 and 87a terminals
with the power, which is on standby on the No. 30 hazard warning lamp relay terminal.
The supplied power flows to the corresponding circuit via the No. 7 and 16 ICM terminals.

If the wiper does not operate at high speed even in heavy rain, check the pins 1 and 2.
In other words, the wiper should operate at high speed when grounding the pins 1 and
2.Symptom 5. The wiper does not operate at high speed even in heavy rain.
Symptom 6. The wiper responses are too fast or slow.
Check whether the variable resistance knob on the multifunction wiper switch is set in
"FAST" or "SLOW".
Notify that the customer can select the sensitivity by selecting the variable resistance
value. And, select a proper stage.
