This fault condition is detectable only when ALC compressor relay output is commanded to the off state. The suspension control module expects to see 12 volts with ALC system in the off state. Check ALC system. Check for disconnected or damaged air lines. See AUTOMATIC LEVEL CONTROL WITH CVRSS article.
