SCU (Suspension Control Unit) SELF-DIAGNOSTIC FUNCTION
The SCU is equipped with a self-diagnostic function in order to ensure that the electronically adjustable
suspension system is operating normally. If this function detects a malfunction in the electronically ad-
justable suspension system, it immediately operates the system under substitute characteristics and
lights the engine trouble and system warning light to alert the rider that a malfunction has occurred in
the system. Once a malfunction has been detected, a fault code is stored in the memory of the SCU.
After the engine has been stopped, the fault code number appears on the display. If there is more than
one fault code number, the numbers are displayed in numerical order starting with the lowest number.
Once a fault code has been displayed, it remains stored in the memory of the SCU until it is deleted.
Checking the engine trouble and system warning light
The engine trouble and system warning light come on for 2.0 seconds after the main switch has been
turned to “ON”. If the engine trouble and system warning light does not come on under this condition,
the lights (LED) may be defective.
SCU detects an abnormal signal from a sensor
If the SCU detects an abnormal signal from a sensor while the vehicle is being driven, the SCU illumi-
nates the engine trouble and system warning light and provides the electronically adjustable suspen-
sion system with alternate operating instructions that are appropriate for the type of malfunction. When
an abnormal signal is received from a sensor, the SCU processes the specified values that are pro-
grammed for each sensor in order to provide the electronically adjustable suspension system with al-
ternate operating instructions that enable the system to continue operating or stop operating,
depending on the conditions.
