2A-6 SUSPENSION DIAGNOSIS DAMPING FORCE CONTROL LOGIC Control Logic that applies on damping force variable suspension is comprised of road sensing driving comfort control logic to increase driving comfort and vehicle speed sensing control logic, anti-roll control logic and anti-dive control
logic to secure control safety.

NORMAL CONTROL Initial Stage When ignition switch is "ON", system initialization will be performed for approx. 3 seconds. During this time, warning lamp will stay ON and damping force will be switched to Hard status. After 3 seconds, warning lamp will turn off and normal control status will be restored. Normal Damping Force Control Establishment Damping force will have Soft Medium Hard status in AUTO mode and Medium Hard status in SPORT mode.
When double control items are satisfied at the same time it will be Hard Medium Soft in order.
Normal Damping Force Control Release Control mode release will be "Hard Medium Soft"or "Medium Soft". In case that returned from Hard status to
Medium status during control, it will be done after elapse of setting times. Returning from Medium status to Soft status
will be done immediately without delay.

1. Turn the ignition switch ON and if ECS system is normal, ECS indicator lamp will turn on for 3 seconds and then go off. However if defective, ECS indicator lamp will flicker in the interval of 0.5 second continuously.
2. Identify fault code with Scanner.
