One-Way Clutch
WARNING: This page is about a different variant/trim than selected.
The one-way clutch is internal to the transaxle and its purpose is to prevent the internal combustion engine from turning in the reverse (counterclockwise) direction. The transaxle control module (TCM) reports the one-way clutch error status to the powertrain control module (PCM). The PCM initiates an appropriate LOS mode and sets the P1A11 (Hybrid powertrain control module - one-way clutch disabled) diagnostic trouble code (DTC) based on the error status it received. The TCM also sets a DTC P1A02 which indicates that the one-way clutch malfunctioned.
