2007 KIA CARNIVAL wiring

2007 > 2.7L V6 GASOLINE >
DESCRIPTION
This specification applies to HCU(Hydraulic Control Unit) and ECU(Electronic Control Unit) of the HECU.(Hydraulic and
Electronic Control Unit)
This specification is for the wiring design and installation of ABS/TCS/ESC ECU.
This unit has the functions as follows.
a. Input of signal from Pressure sensor, Steering angle sensor, Yaw & Lateral G sensor, the wheel speed sensors
attached to each wheel.
b. Control of braking force / traction force/ yaw moment.
c. Failsafe function.
d. Self diagnosis function.
e. Interface with the external diagnosis tester.
Installation position : engine compartment a. Brake tube length from Master cylinder port to HECU inlet port should be max. 1m
b. The position should not be close to the engine block and not lower than the wheel.
OPERATION
The ECU shall be put into operation by switching on the operating voltage (IGN).
On completion of the initialization phase, the ECU shall be ready for operation.
In the operating condition, the ECU shall be ready, within the specified limits (voltage and temperature), to process the
signals offered by the various sensors and switches in accordance with the control algorithm defined by the software
and to control the hydraulic and electrical actuators.
Wheel Sensor signal processing
The ECU shall receive wheel speed signal from the four active wheel sensors.
The wheel signals are converted to voltage signal by the signal conditioning circuit after receiving current signal from
active wheel sensors and given as input to the MCU.
Solenoid Valve Control
When one side of the valve coil is connected to the positive voltage that is provided through the valve relay and the
other side is connected to the ground by the semiconductor circuit, the solenoid valve goes into operation.
The electrical function of the coils are always monitored by the valve test pulse under normal operation conditions.
Voltage limits
a.Overvoltage
When overvoltage is detected(above 16.8 V), the ECU switches off the valve relay and shuts down the system.
When voltage is returned to operating range, the system goes back to the normal condition after the initialization
phase.
b. Undervoltage
In the event of undervoltage(below 9.3 V), ABS control shall be inhibited and the warning lamp shall be turned on.
When voltage is returned to operating range, the warning lamp is switched off and ECU returns to normal operating
mode.
Pump Motor Checking
The ECU performs a pump motor test at a speed of 15km/h once after IGN is switched on.
Diagnostic Interface
Failures detected by the ECU are encoded on the ECU, stored in a EEPROM and read out by diagnostic equipment
when the ignition switch is turned on.
The diagnosis interface can also be used for testing the ECU during production of the ECU and for actuating the HCU
(Air - bleeding line or Roll and Brake Test line).

GENERAL TROUBLESHOOTING INFORMATION
BEFORE TROUBLESHOOTING
1. Check applicable fuses in the appropriate fuse/relay box.
2. Check the battery for damage, state of charge, and clean and tight connections.
a.Do not quick- charge a battery unless the battery ground cable has been disconnected, otherwise you will
damage the generator diodes.
b. Do not attempt to crank the engine with the battery ground cable loosely connected or you will severely
damage the wiring.
3. Check the generator belt tension.
HANDLING CONNECTORS
1.Make sure the connectors are clean and have no loose wire terminals.
2. Make sure multiple cavity connectors are packed with grease (except watertight connectors).
3. All connectors have push - down release type locks (A).
4.Some connectors have a clip on their side used to attach them to a mount bracket on the body or on another
component. This clip has a pull type lock.
5. Some mounted connectors cannot be disconnected unless you first release the lock and remove the connector from
its mount bracket (A).
6.Never try to disconnect connectors by pulling on their wires; pull on the connector halves instead.
7. Always reinstall plastic covers.

CUSTOMER COMPLAINT ANALYSIS CHECK SHEET
TROUBLESHOOTING
There are six areas where a problem can occur: wiring harness, the radio, the cassette tape deck, the CD player, and
speaker. Troubleshooting enables you to confine the problem to a particular area.

REPLACEMENT
1.Remove the right C filler trim(A) and luggage side trim. (Refer to Body group - Interior trim).
2.Remove the diversity(C) after removing 1P connector (A) and radio feeder cable (B).
3.Remove the glass antenna radio amplifier (A) - Left/Right each 1 ea- after removing radio feeder cable (B) and
amplifier wiring (C) from the glass antenna radio amplifier (A).
4.Installation is the reverse of removal.
INSPECTION
GLASS ANTENNA TEST
1. Wrap aluminum foil (A) around the tip of the tester probe (B) as shown.

2007 > 2.7L V6 GASOLINE >
REPLACEMENT
1.Disconnect the nagative(- ) battery terminal.
2. Remove the door trim panel (Refer to Body group - front door).
3. Remove the switch connector (16pin) from the wiring harness, And then loosen the mounting screws (3EA).
4.Remove the switch from the front door panel.

2007 > 2.7L V6 GASOLINE >
INSPECTION
1.Remove the rear seats. (Refer to the Body group - rear seats)
2. Remove the luggage side trim. (Refer to the Body group - interior trim)
3. Open the fuel filler door and disconnect the wiring connector after loosening 2 bolts.
4. Check for continuity between terminal No. 1 and No. 2. If there is no continuity replace the fuel filler door opener.

TROUBLESHOOTING
Check the following items prior to performing Power Sliding Door System service.
1. Manual movement
Make sure the sliding door moves manually. Place the ON/OFF switch on the overhead console in the OFF
position. Move the door manually and check for proper door fit and latch effort. Check for interference with other
body parts such as latch striker, trim, and weather seals.
2. Battery voltage
Make sure the battery is fully charged. The PSD system is an electronic device and requires a minimum battery
voltage to operate. The PSDM(Power sliding door module) monitors the battery voltage present at the PSDM input
battery input and will not permit operation if the battery voltage is out of range.
3. Fuses
Two fuses protect the battery supply to the PSDM(Power sliding door module), one for Power, and one for logic.
Check that the fuses are intact
4. Repeat Operations
Make sure the customer has not been operating the PSD repeatedly while the vehicle is turned off. The battery will
be discharged and the PSDM(Power sliding door module) will not permit operation.
5. Vehicle on Steep Grade
Make sure the customer has not been operating the PSD system when the vehicle is parked on a steep grade
(greater than 30%). The system will operate but the force of gravity and normal flex of the vehicle body may affect
proper operation.
6. Obstacle Detection
The obstacle detection force is not adjustable. Factors that may affect the force are vehicle grade, battery voltage,
or dirt in sliding door tracks.
7. Outside handle response time
When the vehicle has been parked and OFF, there may be a delay before power operation starts after the outside
handle is pulled. This is normal because the PSDM(Power sliding door module) must wake up and check for proper
conditions before starting a power open operation.
8. The sliding doors are not identical. Open and close times and obstacle detection efforts may vary when comparing
the two doors. This is normal and is caused by vehicle build conditions such as door fit and rolling resistance.
9. Scan tool Diagnostic tool
Connect Scan tool to the K- line and check status of system.
