Defect
On large hybrid transit buses, some inverters—which convert electrical current for vehicle drive—have insufficient durability and reliability. Inverter failure may cause the vehicle drive motor and auxiliary motors to stop functioning, triggering the hybrid system warning lamp and a reduction in output. In the worst case, the vehicle may become inoperable and power steering may be lost.
Corrective action
On all vehicles, replace the inverter B-side fuse with a corrected/revised part as an interim measure. The inverter itself is to be replaced periodically with a new unit at an appropriate interval.
