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.
When the height sensor is set up in the vehicle, there is a possibility to cause a tolerance. So, during producing a vehicle in the manufactory, the height sensor's calibration procedure is done for correcting these tolerance. If the calibration procedure isn't done, the ALS ECU would make a warning light to turn on.
When the height sensor's calibration is not carried out, the ALS ECU shows this DTC and turns on the warning light on the cluster.
