ECU KIA CARNIVAL 2007 Owners Manual

Battery Removal
a.If the battery is removed with the system in the ARM state, the system will be placed into the ARM state upon
battery reconnect.
b. The ALARM state will be re- activated if the battery is disconnected, then reconnected, with the system in an
ALARM state.
c. If the battery is disconnected and reconnected with the system in AFTER ALARM state, the alarm will be re-
activated.
d. The system will enter DISARM mode if the battery is disconnected during the ALARM WAIT state.
Panic
a.If RKE PANIC signal is received, Siren output and hazard lamp operate for 27 seconds and the system return to
the previous state as soon as the PANIC function finishes.
b. The PANIC function will be stopped if any RKE signal is received during PANIC activation..
c. If Key reminder switch is ON during PANIC function is operating, PANIC is stopped immediately.
d. If the system goes to ALARM mode during PANIC function is operating, PANIC is stopped immediately and then
ALARM function should be activated.
e. During ALARM state;
If RKE PANIC signal is received, ALARM mode is maintained and PANIC function should be ignored. ALARM has
higher priority than PANIC function.
f. During AFTER_ALARM state;
If RKE PANIC signal is received, AFTR_ALARM mode is maintained and PANIC function should be activated.
Safe & Rescue Mode
The goal of those modes is to be able to cope with failures that may happen on some of the most critical
functionalities (for the driver security) of the system.
Safe Mode
The safe mode is entered in case of system problems such as:
a. Incoherent inputs on monitored signals. In this case, safe mode is the debouncing time before the inputs are
considered INVALID. Note that today, we have no way to detect if the rain/light sensor is in working operation or
not. It means that a driver action will be required in case of failure of this sensor;
b. Loss of the CAN frame containing the monitored signal:
c. Loss of the CAN network: CAN goes to BUS OFF state, safe mode is the time necessary for detecting the BUS
OFF state.
In all cases, the action in safe mode is to maintain the previous state of the system (for lighting and wiping). The list of
monitored signals is the same as in rescue mode
Exiting Safe Mode
The software safe mode is exited and the module goes back to the normal mode when: a. On IPM, hardware inputs return to a coherent state;
b. The lost CAN signal comes back while timeout has not elapsed;
c. The CAN network returns to a normal state without reaching BUS OFF state.
Software safe mode is also exited when the software rescue mode is entered (problem does not disappear).
Hardware safe mode is exited and the module goes back to normal mode if the internal problem disappears (watchdog
is properly triggered again). If the problem stays, hardware safe mode is exited to enter hardware rescue mode.
Rescue Modes
The rescue mode consists in activating some safety functions when IGN2 = ON: a. Switch on the low beams (FAM), park lamps (FAM), tail lamps (RAM) and cluster backlighting (IPM);
b. Unlock of all the doors when the rescue mode is entered with IGN2 = ON
c. Front wipers do not need to be turned on by software in rescue mode because wipers can be turned on by
manually setting the MF switch to low speed. The FAM software must keep the same state as before entering the
rescue mode.
d. When IGN2 = OFF, low beams, park/tail lamps and cluster backlighting are turned off.
Entering Rescue Modes

5.Use the ACTUATION TEST mode to force output devices to operate for testing purposes.
6.Use the "DIAGNOSTIC TROUBLE CODES" mode.
INSPECTION
1.The body network system consists of several ECUs that communicates via a CAN bus. The diagnostic tester is not
directly connected to the CAN bus, but utilises a one- wire communication line (K- line) that connects to a gateway
in the IPM ECU.

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

2.Safety Function
a. When there is an ice in the sensing field, the rain sensor cannot recognize the correct working condition.
Do not operate the rain sensing wipers unless the windshield is completely clear of ice and snow.
b. Glass damage : rain sensor cannot perceive the damaged windshield within the sensing field.
c. The rain senson will not operate properly if detached from the windsheld.
d. If the wiper ECU does not transmit any effective data in 5 seconds, the rain sensor turns off LED.
e. If the intermittent wiper signal is interrupted for >2 sec, the wipers are moved to the parking position.
f. If a rain sensor signal communication error lasts for > 5sec, the wipers are moved into the parking position.
g. If the rain sensor transmits an error to the wiper ECU, the wiper ECU stops the AUTO function after 4.5
seconds.
