Be sure to read and follow the “General Safety Information
and Caution” before doing any work related with the high voltage
system. Failure to follow the safety instructions may result in serious
electrical injuries.
•
Be sure to shut off the high voltage before doing any work
related with the high voltage system(Refer to "High Voltage Shut-off
Procedure"). Failure to follow the safety instructions may result in
serious electrical injuries.
When removing the battery pack assembly to inspect the
battery system, it can be connected to vehicle by using the SST
0K918-E4100, 0K375-E4100, 0K375-E4200.
High Voltage Battery Heater Relay Switch Resistance
[Using multi tester (Relay OFF)]
Inspect the high voltage high voltage battery heater relay by using multi tester when the relay is off
1.
Shut off the high voltage.
(Refer to Battery Control System - "High Voltage Shut-off Procedure")
2.
Remove the power relay assembly (PRA).
(Refer to High Voltage Battery System - "Power Relay Assembly (PRA)")
3.
Measure the resistance between the heater relay (+) switch
terminal and the (+) power terminal which is connected to high voltage
joint box.
Specification : ??(20°C)
[Using GDS (Relay ON)]
1.
Shut off the high voltage.
(Refer to Battery Control System - "High Voltage Shut-off Procedure")
2.
Remove the high voltage battery upper case.
(Refer to High Voltage Battery System - "Case")
3.
Connect the SST(0K918-E4100, 0K375-E4100, 0K375-E4200) to the vehicle.
4.
Connect the GDS to DLC.
5.
Turn the ignition swtich ON.
6.
Activate the battery heater relay by using "Actuation Test" on the GDS as shown in the illustration below.
When the relay is ON, there is a relay operation sound.
High Voltage Battery Heater Relay Coil Resistance
1.
Shut off the high voltage.
(Refer to Battery Control System - "High Voltage Shut-off Procedure")
2.
Remove the power relay assembly (PRA).
(Refer to High Voltage Battery System - "Power Relay Assembly (PRA)")
3.
Measure the resistance between the No.6 and No.7 of power relay assembly connector.
Specification : 104.4 ~ 127.6 ?
Removal
Main Relay, Pre Charge Relay, Pre Charge Resistor, Battery
Current Sensor, High Voltage Battery Heater Relay and the High Voltage
Battery Heater Fuse are integrated in the Power Relay Assembly (PRA). So
Refer to the removal procedure of Power Relay Assembly (PRA).
Installation
Main Relay, Pre Charge Relay, Pre Charge Resistor, Battery

Refer to the installation procedure of Power Relay Assembly (PRA).
Inspection
Check the functions of the ECM in the following procedures:
1.
Turn the ignition key to the "ON" position.
2.
Cover the forward facing sensor.
3.
Flash a light onto the rearward looking sensor.
4.
The ECM should be darkened immediately on detecting light from the rearward ...
Replacement
•
Put on gloves to protect your hands.
•
When prying with a flat-tip screwdriver, wrap it with
protective tape, and apply protective tape around the related parts, to
prevent damage.
