2007 KIA CARNIVAL air condition

CHECK FOR BLOWN FUSE
Check continuity of fuse (10A) from the engine compartment junction block.
Is there continuity?
▶ Repair an open in the wire between ABS fuse and 1 of cluster connector.
▶ Replace the blown fuse.
DETECTING CONDITION
Trouble Symptoms Possible Cause
If the HECU detects trouble, it lights the ABS warning lamp while at
the same time prohibiting ABS control. At this time, the HECU
records a DTC in memory.Even though the normal code is output, the
ABS warning lamp remains ON, then the cause may be probably an
open or short in the ABS warning lamp circuit. a.
An open in the wire
b. Inoperative instrument cluster assembly
c. Inoperative ABS warning lamp module
d. Inoperative HECU
INSPECTION PROCEDURES
CHECK DTC OUTPUT.
1. Connect the Scan Tool to the 16P data link connector located behind the driver's side kick panel.
2. Check the DTC output using Scan Tool.
Is DTC output ?
▶ Repair circuit indicated by code output.
▶ Check instrument cluster.
CHECK INSTRUMENT CLUSTER
Disconnect the cluster connector and turn the ignition switch ON.
Does the ABS warning lamp remains ON?
▶ Replace the instrument cluster.
▶ Check for open the wire.
CHECK FOR OPEN IN THE WIRE
Check for continuity in the wire between cluster and ABS control module.
Is there continuity?
▶ Replace the ABS control module and recheck.
▶ Repair an open in the wire between cluster and ABS control module.
BLEEDING OF BRAKE SYSTEM
1. Remove the reservoir cap and fill the brake reservoir with brake fluid.
If there is any brake fluid on any painted surface, wash it off immediately.

Error conditionBelow 6 pulses in 2 sec. Below 6 pulses in 1 sec.
Prerequisite FR/RR limit SW on Limit setting complete
a. Stop the related motor(seat / pedal) if an error is detected during playing or Easy access function operation.
b. Stop the corresponding motor if an error is detected during manual operation (excluding slide motor).
b. If seat sensor Vcc below 1V is detected by 1s
a. Stop all seat motors running if seat sensor Vcc error is detected during playing or Easy access function operation.
(no buzzer output)
c. Return if seat sensor Vcc is 4V or more.
DETECTING ERRORS FOR ADJUST PEDAL
1.If signal change is below 0.06V per sec though motor is running.
a. Stop the corresponding motor if error is detected during playing or Easy access function operation.
2. If adjust pedal sensor Vcc below 1V is detected by 1s
a. Stop pedal motor running if pedal sensor Vcc error is detected during playing or Easy access function operation.
(no buzzer output)
3. Return if adjust pedal sensor Vcc is 4V or more.
HANDLING ERRORS
1.If errors are discovered, regard them as harness disconnection or sensor failure, and conduct the following
measures.
a. Stop auto control (play or Easy access function operation) if it is under auto control and set off buzzer 10 times
(however, have motors other than the one with an error operate normally).
b. Set off alarm again in case of recurrence of error after restoration of a motor with an error.
c. Complete alarm 10 times though it comes back to normal during error alarm.
d. Stop alarm if receiving memory recall or play order, and set off buzzer in the corresponding function.
e. Manual operation control is allowed even for a motor with errors.
f. Set off buzzer if memory or play order is received even during error.
g. The timing to lift auto control suspension is when repair for the failing motor is completed, and the criteria for
the completion point are as follows:
a. Seat: if signal input is normal with over 6 pulses within a sec. from position sensor of a motor with an error
caused by manual switch.
b. Adjust pedal: if there is change in input of over 3 LSB within 1 sec. from sensor by manual switch.

DESCRIPTION
The Rain sensing windshield wiper system is a wiper system that, in addition to providing normal wiper functions off,
mist, manual low speed, manual high speed, and wash, provides automatic control of automatic intermittent automatic
low, and automatic high speeds.
When the ignition key is in the ON position, the rain sensor will be activated.
SYSTEM FUNCTION
BASIC PRINCIPLE
Emitted Beam from luminosity diode is reflected entirely against the windshield exterior, and then turn into photo diode.
If there is water on the windshield exterior, beam seperates optically, and the degree of remained beam is measured
in the photo diode.
What there is water in the windshield, it means beam is not reflected all, so the degree of lost beam indicates the
degree of glass surface wet.
Rainsensor consist of two luminosity diode, two photo diode, optic fiber and coupling pad.
OPERATION CONTROL
Wiper ECU transmits the signal as a rainsesor, and then the rainsensor perceives the rainwater to transmit to the
wiping order wiper ECU, wiper ECU controls the wiper motor according to the signal.
CONTACT INFLUENCE
The rain sensor can malfunction due to the following conditions : a. Contamination of the measurement surface.
b. Air bubbles between the windshield and the coupling pad contact surface.
c. The movement of coupling pad by vibration.
d. Damaged wiper blade.
AUTO OPERATION
1.Operation Condition
Operation mode Operation condition
Direct mode Switch AUTO is basic operation condition that rain sensor perceives dry
windshield. From this condition, the rain sensor decides the wiper operation
mode depend on the quantity and time of measured rainwater
Intermittent mode Operation pauses between 0.5~5 seconds, then the wipers switch to
intermittent mode
Low speed Operate continuously at low speed
High speed Operate continuously at high speed

DESCRIPTION
When reversing, the driver is not easy to find objects in the blind spots and to determine the distance from the object.
In order to provide the driver safety and convenience, back warning system will operate upon shifting to "R" Ultrasonic
sensor will emit ultrasonic wave rearward and detect the reflected wave. Control unit will calculate distance to the
object using the sensor signal input and output buzzer alarm in three steps (first, second and third alarm).
ALARM RANGE
Upon detecting an object at each range out of 3 ranges as stated below within the operation range, it will generate
alarm.
First alarm : Object comes near to the sensor located at the rear of vehicle, within 81- 120cm ± 15cm
Second alarm : Object comes near to the sensor located at the rear of vehicle, within 41- 80cm ± 10cm
Third alarm : Object comes near to the sensor located at the rear of vehicle, within 40cm ± 10cm
a.Time tolerance of the above waveform : Time ± 10%
b. At nearer distance than 40cm, detection may not occur.
c. Alarm will be generated with vehicle reversing speed 10km/h or less.
For moving target, maximum operation speed shall be target approach speed of 10km/h.
d. When the vehicle or the target is moving, sequential alarm generation or effective alarm may be failed.
e. False alarm, or failure of the alarm to trigger may occur in the following conditions.
a. Irregular road surface, gravel road, reversing toward grass.
b. Horn, motor cycle engine noise, large vehicle air brake, or other object generating ultrasonic wave is near.
c. When a wireless transmitter is used near to the sensor.
d. Dirt on the sensor.
e. Sequential alarm may not occur due to the reversing speed or the target shape.
