The ALS is the abbreviation for "Auto Leveling System". This ALS system automatically controls the height of a vehicle level according to road condition. So it improves riding comfort and steering stability. Among components of the ALS system, the ALS ECU is installed at the lower of driver seat in the vehicle. And it takes a central role in controlling a vehicle level. The ALS ECU also monitors the ALS system and exchanges a lot of signals with the other system's ECU through CAN or Wire.
The ALS ECU monitors ROM/RAM/EEPROM etc. and if it is detected as a fault inside, this DTC is set.
