Prepare your observation

Keep existing warnings or observations for service. This guide does not ask you to probe wiring, disconnect a battery or open a high-voltage assembly.

A reported defect describes the campaign. It does not establish what caused a symptom on your individual vehicle, and absence of a symptom does not establish that an open recall is complete.

Confirm current interim instructions, remedy availability and service arrangements. Keep the dated answer.

Your campaign-specific service questions

Use these questions with the official report. Keep the answers beside the remedy record; “discussed” records a conversation, not a completed repair.

  1. Does the manufacturer confirm that campaign 26V494000 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.

  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.

  3. Which electrical component or software function is covered, and what interim charging, parking or use instructions does the manufacturer give?

    Compare the answer with the reported component: ELECTRICAL SYSTEM:PROPULSION SYSTEM:TRACTION BATTERY.

  4. Which items in the reported replacement remedy for 26V494000 were replaced, and are they identified on the work order?

    Keep the replaced items and the campaign number together so that a later visit can distinguish recall work from other repairs.

  5. What dated document records the remedy performed under 26V494000, and what should I do if the reported concern remains?

    Keep campaign completion and unresolved symptoms as separate questions. A saved worksheet or booked appointment does not establish a repair.
