If it is reported that an Air Hose is missing from connector clip at the Control Module, verify which hose is missing.
The connection clip has 6 locations, but ONLY 5 require air hoses being attached.
There should be 2 gray/black connections on one end and 3 colored connections (pink, yellow, white) on the other end.
The connector between the gray/black and colored hoses is not used and does not require an air hose. This is normal.
