Hyundai Genesis (DH): Rear Glass Defogger / Rear Glass Defogger Printed Heater Repair procedures

Hyundai Genesis (DH) 2013-2016 Service Manual / Body Electrical System / Rear Glass Defogger / Rear Glass Defogger Printed Heater Repair procedures

Inspection
   
Wrap tin foil around the end of the voltmeter test lead to prevent damaging the heater line. Apply pressure on the tin foil with hand and move the tin foil along the grid line to check for open circuits.

1.
Turn on the defogger switch and use a voltmeter to measure the voltage of each heater line in the central part of the glass. If the voltmeter indicates 6V for a conductive line, the line of the rear window is considered to be in good condition.

2.
If a conductive line is burned out within the area between the central part and (+) terminal, the voltmeter will indicate 12V.

3.
If a conductive line is burned out within the area between the central part and (-) terminal, the voltmeter will indicate 0V.

4.
To check for open circuits, Slowly move the test lead toward the section where open circuits seem to exist. Try to find a point where the voltage turns to 0V. The point where the voltage has changed is the open-circuit point.

5.
Use an ohmmeter to measure the resistance of each heater line between a terminal and the center of a grid line, and between the same terminal and the center of one adjacent heater line. The section with a broken heater line will have a resistance twice that in other sections. In the affected section, move the test lead to a position where the resistance sharply changes.

Repair Of Broken Heater Line
Prepare the following items :
1.
Conductive paint.
2.
Paint thinner.
3.
Masking tape.
4.
Silicone remover.
5.
Using a thin brush :
Wipe the glass adjacent to the broken heater line, clean with silicone remover and attach the masking tape as shown. Shake the conductive paint container well, and apply three coats with a brush at intervals of about 15 minutes apart. Remove the tape and allow sufficient time for drying before applying power. For a better finish, scrape excess paint deposits with a knife after the paint has completely dried. (Allow 24 hours).

    Inspection 1. In the body electrical system, failure can be quickly diagnosed by using the vehicle diagnostic system (GDS). (1) Self diagnosis : Checking failure and code number (DTC) (2) Current data : Checking the system input/output data state (3) Actuation test : Checking the system operation condition (4) Additional function : Controlling other features including system option setting and zero point adjustment 2.

    Hyundai Genesis (DH) 2013-2016 Service Manual: Auto Defogging Sensor Description and Operation

    Description The auto defogging sensor is installed on the front window glass. The sensor judges and sends signal if moisture occurs to blow out wind for defogging. The air conditioner control module receives signal from the sensor and restrains moisture and eliminate defog by controlling the intake actuator, A/C, auto defogging actuator,
