YOUR SERVICE QUESTIONS 1. Does the manufacturer confirm that campaign 21V387000 applies to this VIN, including the report’s equipment and production restrictions?

What remedy, required parts or software, and appointment arrangements are currently available for this VIN, and which interim instructions apply? The source does not explicitly establish current remedy availability. Ask the manufacturer about the applicable remedy, required parts or software, appointment arrangements and any interim instructions. Discussion status / answer: __________ 3. Which braking or stability-control function is involved, and what current use or transport guidance applies to this VIN? Compare the answer with the reported components: SERVICE BRAKES, HYDRAULIC:CRITICAL FASTENERS; SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:DISC:CALIPER. Discussion status / answer: __________ 4. If an inspection determines which work is needed, what was inspected, what was found, and which corrective work followed? Ask for the inspection result as well as the final action.

Which items in the reported replacement remedy for 21V387000 were replaced, and are they identified on the work order?
