Coverage gaps

  • Exact model-family pages remain gated until an official or manual-backed source supports the model-specific wording.
  • Parts and service handoffs are not shown as recommendations until the source context is strong enough.

How this guide should be used

  • Use the source links to verify the original manufacturer context.
  • Check model notes before treating a display code as universal.
  • Prefer safe first checks before any disassembly or parts decision.

Current limitations

  • Manufacturer guidance can differ by model family and region.
  • Alias/display variants are only added when the source supports them.
  • Manual-backed model detail is planned but not bulk-generated.
