SELF-DIAGNOSTIC FUNCTION
The this vehicle is equipped with a self-diagnostic function in order to ensure that the steering damper
system is operating normally. If this function detects a malfunction in the system, illuminates the steer-

function has been detected, a fault code number is stored in the memory of the ECU.
Checking the steering damper warning light
The steering damper warning light comes on for around 2 seconds after the main switch has been set
to "ON". If the warning light does not come on, the warning light (LED) may be defective.
