YOUR SERVICE QUESTIONS 1. Does the manufacturer confirm that campaign 24V797000 applies to this VIN, including the report’s equipment and production restrictions? A matching model and year is only a starting point. The official lookup or manufacturer must establish the individual vehicle’s status. Discussion status / answer: __________ 2. 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 engine or transmission component is covered, and does an existing drivability problem need separate diagnosis? Compare the answer with the reported components: POWER TRAIN:AUTOMATIC TRANSMISSION:FLUID/LUBRICANT:VALVES/VALVE BODY; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE:SOFTWARE. Discussion status / answer: __________ 4. Which module and software completion record demonstrate that the update for 24V797000 was applied? Ask the service provider how the campaign-specific software remedy is documented. A dashboard reset is not evidence of the specified update. Discussion status / answer: __________ 5. What dated document records the remedy performed under 24V797000, and what should I do if the reported concern remains? Keep campaign completion and unresolved symptoms as separate questions.

Campaign listed as open: confirm current instructions, availability and remedy arrangements. Campaign not listed as open: reconcile repair history and lookup coverage with the manufacturer if needed. A zero-open result does not diagnose symptoms. Work order records completed recall work: keep the exact campaign and dated remedy record; report unresolved symptoms separately. YOUR RECORD Check date: __________ Official lookup result: __________ Service arrangement: __________ Existing observation: __________ Questions and work-order notes (no VIN or plate needed): __________ LOOKUP LIMITS A model/year match does not establish VIN eligibility.
