Hino 500 SERIES (2011–2017)
What the hazard is
If the ACU is unable to operate, a warning light in the vehicle may appear, and the vehicle may not operate. This may lead to an accident risk for the occupant and other road users.
What to do
Owners of affected vehicles should contact their local Hino dealership to get their vehicle's AMT ECU reprogrammed. The two ACU motors will also be replaced free of charge. Consumers can contact Hino on 1300 01 HINO (1300 014 466) or their local Hino dealer.
Defect
The Automatic Clutch Unit (ACU) has two motors that operate the clutch. An ACU motor may not operate correctly, if wear occurs on the internal brush. If one motor fails, the other can compensate for this and continue to operate the clutch system. In this situation the ACU may not function correctly, due to the ACU control software being unable to account for changes, to the ACU motors operating characteristics.
