We have published a shareable English workshop manual for the Toyota Hiace KDH201 / Regius Ace fridge van with a DENSO Aeon unit (CGA 138 · R134a). Built so another workshop can service this Japanese-import van without relying only on Japanese-language books.

What is in the PDF

  • DENSO Aeon English body — safe use, operation, inspection, maintenance, faults
  • Diagnostic code list (F3 / F4 / LC1 and related)
  • Original Japanese fuse table with English translation beside it
  • This-van fuse box C8639-44010, under-dash COOLER 15A, and panel photos
