2 Heated steering control : BCM(body control module) integrated management
Operation
The push-return switch transmits signals to the steering wheel heating module
Pressing the switch on once repeatedly cycles the unit between the ON and OFF modes
If the power is cut off during operation, the switch is reset to off status
Therefore steering wheel heating module is initialized to off status

Inpection
1 Measure a resistance of NTC and Heated pad
– NTC resistance(Black / Yellow, Black) - 10.0 kΩ ± 10% (25°C)
– Heated pad resistance (Yellow, Black) - 1.6 ~ 2.0 Ω ± 10%
2 Measure a temperature
– The temperature of wheel surface grip must rise from -20°C to 20°C within 6 minute
– The temperature of wheel surface grip must keep 38°C ± 4°C after 25 minute
– At that time switch on, all measure point (1~8)
3 Heated steering wheel switch
– Check the continuity between the switch terminals as the Heated steering wheel switch is engaged

Steering System
Description
EPS (Electric power steering, Column assist type) system uses an electric motor to assist the steering effort andit operate without
consumption of engine output
EPS control module controls the motor operation according to information received from the each sensor and CAN (Controller Area Network),resulting in a more precise and timely control of steering assist than conventional engine-driven hydraulic systems Components (Steering Angle Sensor, Torque Sensor, Fail-safe relay, etc.) of the EPS system are located inside the steering column EPS unit assembly, steering column, and EPS unit assembly must not be disassembled for inspection They must be replaced if necessary
Note With Regard to diagnosis
damage can occur.The steering wheel could pull to one side by using the dropped parts.- Precise parts of motor/ECU are sensitive to vibration and impact.- Overload can cause unexpected damage
- Do not use the impacted EPS.- Do not overload each parts
welding point- Broken PCB- Damaged precise parts
can cause malfunction of the torque sensor
- Do not impact the connecting parts (When inserting and torquing)- Use the specified tool to remove the steering wheel (Do not hammer on it)- Do not use the impacted EPS
(Uneven between LH and RH)
Do not use the impacted EPS
power operation- Malfunction of EPS
Disconnection between harness connecting portion and harness
Do not overload the harness
- Keep the normal temperature and proper moisture, while storaging- Avoid drowning
1 Do not impact the electronic parts, if they are dropped or impacted, replace them with new ones
2 Avoid heat and moisture to the electronic parts
3 Do not contact the connect terminal to avoid deformation and static electricity
4 Do not impact the motor and torque sensor parts, if they are dropped or impacted, replace them with new ones
5 The connector should be disconnected or connected with IG OFF

The following symptoms may occur during normal vehicle operation and if there is no EPS warning light illumination, it is not malfunction
of EPS system
• After turning the ignition switch on, the steering wheel becomes heavier while it performs EPS system diagnostics, for about 2
seconds, then it becomes normal steering condition
• After turning the ignition switch on or off, EPS relay noise may occur but it is normal
• When it is steered, while the vehicle is stopped or in low driving speed, motor noise may occur but it is normal operating one
ASP (Absolute Steering Position) calibration or EPS type recognition
• Check if the battery is fully charged before ASP calibration or EPS type recognition
• Be careful not to disconnect any cables connected to the vehicle or scan tool during ASP calibration or EPS type recognition
• When the ASP calibration or EPS type recognition is completed, turn the ignition switch off and wait for several seconds, then start the engine to confirm normal operation of the vehicle
ASP Calibration
1 Connect self-diagnosis connector(16pins) located in the lower of driver side crash pad to self-diagnosis device
2 Turn the self-diagnosis device after key is ON
3 After Selecting the "vehicle model" and "system", select the "ASP Calibration" on GDS vehicle selection screen
Trang 104 Follow the process as below.
