0ZN is listed, but the option does not seem to work

The safest interpretation is the one tied to the exact VIN, model year, platform, and market. In general, 0ZN matches “Computer-selected rear suspension component. This code identifies a factory suspension component, spring selection, or chassis calibration” but the included hardware can vary between applications.

On these vehicles, similar descriptions can use different codes because of supplier changes or package combinations. The code itself is useful, but the VIN-specific parts catalog is better before ordering anything.

Some codes are reused across several brands, but that does not always mean the parts are identical. Model, trim, drivetrain, and production date can all matter.

The dealer should be able to pull a VIN-specific equipment or parts record. Ask them to search by VIN rather than entering only the three-character code.

If the feature is listed but not working, scan all related modules before assuming it was removed. A stored fault, replacement module, or configuration mismatch can make original equipment appear absent.

I would start by checking the original build sheet and then compare the physical equipment on the vehicle. A sales or option code confirms the factory record, but it does not prove that every original component is still installed.

Check the production month as well as the model year. Mid-year changes are one reason two vehicles with the same badge can have different hardware or descriptions.
