3. Check the terminals and connectors of the steering angle sensor for damage, bend and loose connection
(unit side and connector side).
OK or NG
OK >> GO TO 2.
NG >> Repair the terminal and connector.
2. CHECK HARNESS FOR OPEN CIRCUIT
1. Disconnect the connector of steering angle sensor.
2. Check the resistance between the steering angle sensor harness connector terminals.
OK or NG
OK >> GO TO 3.
NG >> Repair the steering angle sensor branch line.
3. CHECK POWER SUPPLY AND GROUND CIRCUIT

AUTO LIGHT SYSTEM

AUTO LIGHT SYSTEMPFP:28491
Component Parts and Harness Connector LocationBKS001O5
System DescriptionBKS001O6

BCM (Body Control Module) controls auto light operation according to signals from optical sensor, lighting
switch and ignition switch.

IPDM E/R (Intelligent Power Distribution Module Engine Room) operates parking, license plate, tail, front
fog lamps and headlamps according to CAN communication signals from BCM.

Optical sensor detects ambient brightness of 800 to 2,500 lux. And optical sensor converts light (lux) to
voltage, then sends the optical sensor signal to BCM.
OUTLINE
The auto light control system has an optical sensor inside it that detects outside brightness.
When the lighting switch is in AUTO position, it automatically turns ON/OFF the parking, license plate, tail,
front fog lamps and headlamps in accordance with the ambient light. Sensitivity can be adjusted in four steps.
For the details of the setting, Refer to LT- 1 9 , "
WORK SUPPORT" .
Optical sensor, power is supplied

from BCM terminal 17

to optical sensor terminal 1.
Optical sensor, ground is supplied

to optical sensor terminal 3

from BCM terminal 18.
When ignition switch is turn to ON position, and
When outside brightness is darker than prescribed level, input is supplied

from optical sensor terminal 2

AUTO LIGHT OPERATION
Applicable lamps

Low beam headlamp

Parking, license plate and tail lamps

High beam headlamp (with the lighting switch in HIGH BEAM position)

Front fog lamp (with the lighting switch in front fog lamp ON position)
When the lighting switch is in AUTO position with the ignition switch in ON position, BCM detects the AUTO
LIGHT (ON) by BCM combination switch reading function. BCM turns automatically ON/OFF the applicable
lamps according to ambient brightness depending on the following condition.

It turns ON applicable lamps in 3 seconds when ambient brightness is less than 1250 lux.

This lighted lamps is turned OFF in 5 seconds when ambient brightness becomes 2500 lux or higher.
Releasing Function:

Turn ignition switch to the OFF position, or

Change lighting switch to the OFF, 1ST, 2ND position.
NOTE:
Timing for when lamps turn ON/OFF can be changed by the function setting of CONSULT-II. Refer to LT- 1 9 ,

CAN Communication System DescriptionBKS001O7
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitBKS001O8
