INSPECTION
While operating the components, check whether the operations are normal as shown in the timing chart.
1. The defog function can be activated only when engine is running and ignition key is in RUN position.
If the defogger is switched ON, the defogger will stay ON for 20 minutes duration.
While Windshield Defog is on, the windshield defog button is illuminated
If the switch is pushed again while defog is already active, defog stops.
If the engine stops while defog is on, defog stops and it is not automatically turned on when the engine is started
again.
Rear defog works exactly in the same way as windshield defog using the Rear Defog Switch button as input.
2.Rear Defog Pause
When IPM receives tailgate flasher control CAN message transition to tailgate flash value, rear defog is inhibited for
30s.
The 20 min rear defog timer is frozen during this pause.
If the user turns on rear defog function while this pause is going on, rear defog is set to ON only at the end of the
pause.
This pause has no impact on Rear Defog Switch illumination.
When IPM receives tail gate open CAN message transition to OPEN value, this 30 s rear defog pause is also
started, it works the same way as described above.

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
The immobilizer system will disable the vehicle unless the proper ignition key is used, in addition to the currently
available anti- theft systems such as car alarms, the immobilizer system aims to drastically reduce the rate of auto
theft.
1. SMARTRA type immobilizer
a. The SMARTRA system consists of a transponder located in the ignition key, an antenna coil, a SMARTRA unit,
an indicator light and the PCM(ECM).
b. The SMARTRA communicates to the PCM(ECM) (Engine Control Module) via a dedicated communications line.
Since the vehicle engine management system is able to control engine mobilization, it is the most suitable unit
to control the SMARTRA.
c. When the key is inserted in the ignition and turned to the ON position, the antenna coil sends power to the
transponder in the ignition key. The transponder then sends a coded signal back through the SMARTRA unit to
the PCM(ECM).
d. If the proper key has been used, the PCM(ECM) will energize the fuel supply system. The immobilizer indicator
light in the cluster will simultaneously come on for more than five seconds, indicating that the SMARTRA unit
has recognized the code sent by the transponder.
e. If the wrong key has been used and the code was not received or recognized by the PCM(ECM) the indicator
light will continue blinking for about five seconds until the ignition switch is turned OFF.
f. If it is necessary to rewrite the PCM(ECM) to learn a new key, the dealer needs the customer's vehicle, all its
keys and the Scan tool (pro) equipped with an immobilizer program card. Any key that is not learned during
rewriting will no longer start the engine.
g. The immobilizer system can store up to four key codes.
h. If the customer has lost his key, and cannot start the engine, contact motor service station.
COMPONENTS OPERATIONS
PCM (Power Train Control Module)
1. The PCM(ECM) carries out a check of the ignition key using a special encryption algorithm, which is programmed
into the transponder as well as the PCM(ECM) simultaneously. Only if the results are equal, the engine can be
started. The data of all transponders, which are valid for the vehicle, are stored in the PCM(ECM).

SMARTRA unit
The SMARTRA carries out communication with the built- in transponder in the ignition key. This wireless
communication runs on RF (Radio frequency of 125 kHz). The SMARTRA is mounted behind of the crush pad under
panel close to the antenna coil for RF transmission and receiving.
The RF signal from the transponder, received by the antenna coil, is converted into messages for serial
communication by the SMARTRA device. And, the received messages from the PCM(ECM) are converted into an RF
signal, which is transmitted to the transponder by the antenna.
The SMARTRA does not carry out the validity check of the transponder or the calculation of encryption algorithm. This
device is only an advanced interface, which converts the RF data flow of the transponder into serial communication to
the PCM(ECM) and vice versa.
TRANSPONDER (Built-in keys)
The transponder has an advanced encryption algorithm. During the key teaching procedure, the transponder will be
programmed with vehicle specific data. The vehicle specific data are written into the transponder memory. The write
procedure is once only; therefore, the contents of the transponder can never be modified or changed.
Antenna coil
The antenna coil (A) has the following functions.a. The antenna coil supplies energy to the transponder.
b. The antenna coil receives signal from the transponder.

TEACHING PROCEDURES
1.Key Teaching Procedure
Key teaching must be done after replacing an inoperative PCM(ECM) or when providing additional keys to the
vehicle owner.
The procedure starts with an PCM(ECM) request for vehicle specific data (PIN code: 6digits) from the tester. The
"virgin" PCM(ECM) stores the vehicle specific data and the key teaching can be started. The "learnt" PCM(ECM)
compares the vehicle specific data from the tester with the stored data. If the data are correct, the teaching can
proceed.
If incorrect vehicle specific data have been sent to the PCM(ECM) three times, the PCM(ECM) will reject the
request of key teaching for one hour. This time cannot be reduced by disconnecting the battery or any other
manipulation. After reconnecting the battery, the timer starts again for one hour.
The key teaching is done by ignition on with the key and additional tester commands. The PCM(ECM) stores the
relevant data in the EEPROM and in the transponder. Then the PCM(ECM) runs the authentication required for
confirmation of the teaching process. The successful programming is then confirmed by a message to the tester.
If the key is already known to the PCM(ECM) from a previous teaching, the authentication will be accepted and the
EEPROM data are updated. There is no changed transponder content (this is impossible for a learnt transponder).
The attempt to repeatedly teach a key, which has been taught already during the same teaching cycle, is
recognized by the PCM(ECM). This rejects the key and a message is sent to the tester.
The PCM(ECM) rejects invalid keys, which are presented for teaching. A message is sent to the tester. The key
can be invalid due to faults in the transponder or other reasons, which result from unsuccessful programming of
data. If the PCM(ECM) detects different authenticators of a transponder and an PCM(ECM), the key is considered
to be invalid.
The maximum number of taught keys is 4
If an error occurs during the Immobilizer Service Menu, the PCM(ECM) status remains unchanged and a specific
fault code is stored.
If the PCM(ECM) status and the key status do not match for teaching of keys, the tester procedure will be stopped
and a specific fault code will be stored at PCM(ECM).

2.User Password Teaching Procedure
The user password for limp home is taught at the service station. The owner of the vehicle can select a number
with four digits.
User password teaching is only accepted by a "learnt" PCM(ECM). Before first teaching of user password to an
PCM(ECM), the status of the password is "virgin" No limp home function is possible.
The teaching is started by ignition on, with a valid key and sending the user password by tester. After successful
teaching, the status of the user password changes from "virgin" to "learnt"
The learnt user password can also be changed. This can be done if the user password status is "learnt" and the
tester sends authorization of access, either the old user password or the vehicle specific data. After correct
authorization, the PCM(ECM) requests the new user password. The status remains "learnt" and the new user
password will be valid for the next limp home mode.
If incorrect user passwords or wrong vehicle specific data have been sent to the PCM(ECM) three times, the
PCM(ECM) will reject the request to change the password for one hour. This time cannot be reduced by
disconnecting the battery or any other actions. After reconnecting the battery, the timer starts again for one hour.
