Auto Light Sensor

- Inspection In the state of IGN1 ON, when the multi function switch module detects auto light switch on, tail lamp relay output and head lamp low relay output are controlled according to auto light sensor's input.If IGN1 ON, The BCM monitors the range of this supply and raises up a failure as soon as the supply’s voltage is out of range. Then this failure occurs and as long as this is present, the head lamp must be turned on without taking care about the sunlight level provided by the sensor.This is designed to prevent any head lamp cut off when the failure occurs during the night. - Removal

1.Disconnect the negative (-) battery terminal.

2.Remove the photo & auto light sensor (A) from crash pad upper side by using screw (-) driver.

3.Remove the auto light connector.

- Installation

1.Reconnect the auto light connector.

2.Install the auto light sensor.

Hyundai Accent (HC) (2017 - 2022) Service Manual: ETC (Electronic Throttle control) System

- Description The Electronic Throttle Control (ETC) System consists of a throttle body with an integrated control motor and throttle position sensor (TPS). Instead of the traditional throttle cable, an Accelerator Position Sensor (APS) is used to receive driver input. The ECM uses the APS signal to calculate the target throttle angle; the position of the throttle is then adjusted via ECM control of the ETC motor.
