PRECAUTION
1.PRECAUTION FOR USING BATTERY DURING INSPECTION
(a)While using the battery during inspection, do not bring the positive and negative tester probes too close to each other as a short circuit may occur.
2.PRECAUTION FOR HEADLIGHT BULB REPLACEMENT
(a)If even a thin film of oil is left on the surface of the halogen light, the bulb may be damaged because the light will burn at a higher temperature.
(b)Handle any halogen light with great care. Dropping, hitting or damaging the bulb, in any way, may result in exploding and shattering because the internal pressure is high.
(c)Always prepare a new bulb for immediate replacement. While replacing the bulb, the lens may attract dust and moisture if removed from the vehicle for too long.
(d)Always use a bulb of the same wattage for replacement.
(e)Firmly reinstall the socket after bulb replacement. The lens may become cloudy or the light cavity may fill with water through the gaps around the socket.

SYSTEM DESCRIPTION
1. MANUAL LIGHT CONTROL SYSTEM
This system functions if the lights such as the headlights and taillights come on by manual operation of the light control switch.
(a) The main body ECU controls this system based on the signals listed below.
Input |
Output |
|
Lights that illuminate |
|
|
|
|
|
|
|
|
• |

3. LIGHT AUTO TURN OFF SYSTEM |
|
When the headlights and taillights are on through the |
|
operation of the automatic light control system or through |
|
the light control switch, if the ignition switch is turned off |
|
and all doors are closed, this system continues to |
|
illuminate the headlights and taillights for approximately |
|
30 seconds, and then turns off the headlights and |
|
taillights. |
|
However, if the ignition switch is turned off and all doors |
LI |
are locked, this system turns off the headlights and |
|
taillights immediately. |
|
(a) The main body ECU controls this system based on |
|
|
the signals listed below. |
|||
|
|
|
|
|
Input |

|
operation, or if a door is opened, the illuminated entry |
|
|
|
system turns on the interior light and the ignition key |
|
|
|
cylinder light. |
|

POWER DISTRIBUTOR |
|
Power Distributor (Engine Room J/B) |
(a) The power distributor (engine room J/B assembly) is |
|
|
installed in the engine room R/B. |

|
|
distributor (engine room J/B assembly) and high |
|
|
beam headlight bulbs, a fail-safe function operates. |

DIAGNOSIS SYSTEM
1.DESCRIPTION
(a)Lighting system data and the Diagnostic Trouble Codes (DTCs) can be read from the Data Link Connector 3 (DLC3) of the vehicle. When the system seems to be malfunctioning, use the intelligent tester to check for malfunctions and perform repairs.

Intelligent Tester |
|
(b) |
Connect the cable of the intelligent tester to the |
|
|
DLC3, turn the ignition switch on (IG) and attempt to |
|
|
|
|
use the tester. If the display indicates that a |
|
|
|
communication error has occurred, there is a |
|
|
|
problem either with the vehicle or with the tester. |
|
|
|
HINT: |
|
|
|
• If communication is normal when the tester is |
|
|
|
connected to another vehicle, inspect the DLC3 |
|
|
|
of the original vehicle. |
|
|
|
• If communication is still not possible when the |
|
|
|
tester is connected to another vehicle, the |
|
|
|
problem may be in the tester itself. Consult the |
DLC3 |
|
|
Service Department listed in the tester's |
|
|
instruction manual. |

DATA LIST / ACTIVE TEST
1.READ DATA LIST
HINT:
Using the intelligent tester DATA LIST allows switch, actuator and other item values to be read without removing any parts. Reading the DATA LIST early in troubleshooting is one way to save time.
(a)Connect the intelligent tester to the DLC3.
(b)Turn the ignition switch on (IG).
(c)Read the DATA LIST according to the display on the tester.
