2007 KIA CARNIVAL brake

2007 > 2.7L V6 GASOLINE >
FAILURE DIAGNOSIS
1.In principle, ESP and TCS controls are prohibited in case of ABS failure.
2. When ESP or TCS fails, only the failed system control is prohibited.
3. However, when the solenoid valve relay should be turned off in case of ESP failure, refer to the ABS fail- safe.
4. Information on ABS fail- safe is identical to the fail- safe in systems where ESP is not installed.
MEMORY OF FAIL CODE
1.It keeps the code as far as the backup lamp power is connected. (O)
2. It keeps the code as long as the HCU power is on. (X)
FAILURE CHECKUP
1.Initial checkup is performed immediately after the HECU power on.
2. Valve relay checkup is performed immediately after the IG2 ON.
3. It executes the checkup all the time while the IG2 power is on.
4. Initial checkup is made in the following cases.
(1) When no failure is detected
(2) When ABS and ESP are not in control.
(3) Initial checkup is not made after ECU power on.
(4) If the vehicle speed is over 5 mph(8 km/h) when the brake lamp switch is off.
(5) When the vehicle speed is over 24.8 mph(40 km/h).
5. Though, it keeps on checkup even if the brake lamp switch is on.
6. When performing ABS or ESP control before the initial checkup, stop the initial checkup and wait for the HECU
power input again.
7. Judge failure in the following cases.
(1) When the power is normal.
(2) From the point in which the vehicle speed reaches 4.9 mph(8 km/h) after HECU power on.
COUNTERMEASURES IN FAIL
1.Shut the system down and perform the following actions and wait for HECU power OFF.
2. Turn the valve relay off.
3. Do not perform any ABS/TCS/ESC functions until normal operating condition is restored.
WARNING LAMP ON
1.ABS warning lamp turns on when ABS is malfunctioning.
2. ESP operation lamp turns on when ESP is malfunctioning.
When power voltage and valve relay voltage are abnormal, input/output related failure judgment is not made.

c.A steering angle sensor used in ESP adjusts 0° setting of steering wheel through K- line or CAN
communication.
2. STEERING ANGLE SENSOR (SAS) CALIBRATION METHOD

A driver moves the vehicle to the front and back about 5 meters twice or three times.
(2) Connect Scan tool to the vehicle.
(3) Select Brake system.
(4) Select Steering angle sensor(SAS) calibration.
(5)Perform the Steering angle sensor(SAS) calibration.
(6)Perform the procedure continuously.

2.Installation is the reverse the removal.
a.Make sure the connector is plugged in properly.
LOWER PANEL REPLACEMENT

Auto Light Function
1.The Auto light function is active when the Head lamp switch is positioned to 'Auto' and the Key is in RUN position.
The auto light sensor is powered on the status ACC, START and RUN of the key position. Based on the Auto light
sensor values corresponding to the exterior brightness level, it controls automatically the lighting of the Park and tail
lamps or / and the Head lamps Low Beam depending on the country.
2. Auto light Sensor detection table
Mode Tail Lamps
Head Lamps Low Beam
Lux (Lux) Voltage(V) Lux (Lux)Voltage(V)
ON < 24 ± 5.2 <1.77 ± 0.08V Same as Tail lamps
OFF > 48 ± 10.5 > 3.47 ± 0.1V Same as Tail lamps
Drl Function
1.The Auto DRL function operates the Head lamps High Beam at 50% of full illumination.
The park and tail are managed by the auto light sensor.
The Auto DRL function is active if:
a. The ignition switch is on RUN position
b. The engine is running.
c. The Park brake switch is OFF.
2. The DRL function is inactive when one of above conditions is released.
When the DRL function is active, the Head lamps High Beam can't be turned ON, except for the Flash To Pass
activation.

Easy Access
1.Description
The easy access function permits automatic rearward movement of the driver seat when the key is removed from
the cylinder. Automatic forward movement of the driver seat will take place when the key is inserted into the
cylinder. This function will be enabled on IMS equipped vehicles when the AUTO button is pressed.
Inhibit Switch should be in P- Position for the Easy Access operation.

2. Functional Diagram

Gearbox Status
The status of the gearbox is sent on the CAN network when the CAN network is available.
Oil Pressure Switch Status
The status of the oil pressure switch is sent on the CAN network when the CAN network is available.
Fuel Filter Status
The FAM receives on digital input the status of the fuel filter (Fuel Filter Input) and sends it (Fuel filter switch) on the
CAN network.
Washer Fluid Sensor Status
The FAM receives on digital input the status of the washer fluid sensor and sends it on the CAN network.
If Washer Fluid Low Input is LOW for more than 10 sec, FAM sends the warning message.
