This bulletin applies to 2014 Toyota Prius C vehicles equipped with a 1.5L engine. Some customers may complain about a MIL on. The technician may find DTC P0A80 stored. In these cases, the HV battery would need to be replaced. Along with HV battery replacement, the battery cooling system filter will either need cleaning or replacement.
For vehicle produced prior to September 2013, install a new filter G923G-52010.
For vehicles produced after September 2013, clean the dust-off filter. Remove the front floor cover for inspection (under the rear seat on the driver side).
