SCC(Smart Cruise Control) checks the battery voltage and generator output voltage to determine whether the SCC system can operate normally or not.
The normal battery voltage range is essential for controlling the SCC system as intended.
SCC sets this code if terminal input voltage declines 9V when engine run. if terminal input voltage climbs by normal voltage range ,SCC recovers to normal state .
