DTC P272D : Park Pawl Motor Control Circuit Too High

General Description

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

The park pawl actuator driver unit controls the park pawl actuator to switch to and unlock the P position. The park pawl actuator driver unit uses three lines (MAU/P-ACT_MTR_U, MAV/P-ACT_MTR_V, and MAW/P-ACT_MTR_W) to monitor the voltage applied to the park pawl actuator. If the voltage applied to the park pawl actuator is a specified value or less for a set time, the powertrain control module (PCM) receives a malfunction from the park pawl actuator driver unit and stores a DTC.

Possible Cause

NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.

Park pawl actuator driver unit MAU/P-ACT_MTR_U line open (includes a loose or disconnected connector)
Park pawl actuator driver unit MAV/P-ACT_MTR_V line open (includes a loose or disconnected connector)
Park pawl actuator driver unit MAW/P-ACT_MTR_W line open (includes a loose or disconnected connector)
Park pawl actuator relay P-ACT_RLY_CL- line open (includes a loose or disconnected connector)
Line between the park pawl actuator and the park pawl actuator relay open
Park pawl actuator relay power supply line open
Park pawl actuator driver unit MAU/ACT_MTR_U line short to ground
Park pawl actuator driver unit MAV/P-ACT_MTR_V line short to ground
Park pawl actuator driver unit MAW/P-ACT_MTR_W line short to ground
Park pawl actuator relay stuck off
Park pawl actuator driver unit internal failure

Confirmation Procedure

Operating Condition

Turn the vehicle to the ON mode, and wait at least 10 seconds.

With the HDS

None.

Diagnosis Details

Conditions for setting the DTC

When a malfunction is detected, the shift position indicator blinks and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the PCM memory. The MIL does not come on.

Conditions for clearing the DTC

The shift position indicator comes off by turning the vehicle to the OFF (LOCK) mode. The Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the 12 volt battery.
