In the body electrical system, failure can be quickly diagnosed by using the vehicle diagnostic system (Diagnostic tool).
The diagnostic system (Diagnostic tool) provides the following information.
(1)
Fault Code Searching : Checking failure and code number (DTC)
(2)
Data Analysis : Checking the system input/output data state
(3)
Actuation test : Checking the system operation condition
(4)
S/W Management : Controlling other features including system option setting and zero point adjustment
2.
If diagnose the vehicle by Diagnostic tool, select "DTC Analysis" and "Vehicle".

3.
If check current status, select the "Data Analysis" and "Car model".

4.
Select the 'IBU_BCM' to search the current state of the input/output data.

    Tire Rotation

    To equalize tread wear, HYUNDAI recommends that the tires be rotated according to the maintenance schedule or sooner if irregular wear develops.

    During rotation, check the tires for correct balance.

    When rotating tires, check for uneven wear and damage. Abnormal wear is usually caused by incorrect tire pressure, improper wheel alignment, out-ofbalance wheels, severe braking or severe cornering. Look for bumps or bulges in the tread or side of the tire. Replace the tire if you find any of these conditions. Replace the tire if fabric or cord is visible. After rotation, be sure to bring the front and rear tire pressures to specification and check lug nut tightness (proper torque is 79~94 lbf·ft [11~13 kgf·m]).
