DTC P1711: Park Pawl Unit Malfunction

General Description

Courtesy of HONDA, U.S.A., INC.

The park pawl actuator driver unit controls shifting/releasing of the park pawl actuator to/from the P position. The park pawl actuator driver unit monitors the malfunctions of the built-in CPU. If abnormal behavior of the CPU continues to be detected for a specified length of time or more, the powertrain control module (PCM) receives malfunction from the park pawl actuator driver unit, and stores a DTC.
