48Q — Exterior molding color: Dark Yellow Green Metallic (91). This code identifies the factory color, finish, or type of the listed molding. Browse RPO codes →
My 2020 Chevrolet Corvette did not appear to leave the factory with the setup identified by 48Q: “Exterior molding color: Dark Yellow Green Metallic (91). This code identifies the factory color, finish, or type of the listed molding” I am considering adding it. Does the retrofit normally involve control-module programming, a different harness, or additional hardware?

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.

That code should be read as a factory configuration identifier, not necessarily a guarantee of a separate dashboard control. Some equipment operates automatically or is bundled with another system.

A window sticker is helpful for customer-facing option names, while the build sheet is usually more detailed. If they disagree, the vehicle-specific dealer equipment list can help connect the sales name to 48Q.

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.

This sounds more like a documentation mismatch than a decoder error. Different databases often shorten the same factory description in different ways.

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.

I would avoid buying retrofit parts until the connectors and module support are confirmed. Returning electronic or VIN-programmed components can be difficult.
