P05A27E |
Active Grille Air Shutter "A" Actuator Stuck On |
The following condition is met and the ECM receives a malfunction signal 17 times* (2 trip detection logic):
|
|
Comes on |
DTC stored |
SAE Code: P05A3 |
|
P05A27F |
Active Grille Air Shutter "A" Actuator Stuck Off |
The following condition is met and the ECM receives a malfunction signal 17 times* (2 trip detection logic):
|
|
Comes on |
DTC stored |
SAE Code: P05A3 |
HINT:
*: For every 65 ms that the ECM receives a grille shutter system malfunction signal from the grille shutter ECU (swing grille actuator assembly) the ECM determines it has received the signal 1 time. If the ECM determines the malfunction signal has been received 17 consecutive times (the signal is received for approximately 1 second continuously), it will store a DTC.
MONITOR DESCRIPTION
If the grille shutter ECU (swing grille actuator assembly) detects that the grille shutter motor (swing grille actuator assembly) is performing an open or close operation for longer than the threshold, it will output a malfunction signal to the ECM and the ECM will store a DTC.

CAUTION / NOTICE / HINT
NOTICE:
- In order to ensure safety, before performing troubleshooting or removing the swing grille actuator assembly or radiator shutter sub-assembly, change the grille shutter control mode to maintenance mode.
-
Vehicle Control History may be stored in the hybrid vehicle control ECU assembly if the engine is malfunctioning. Certain vehicle condition information is recorded when Vehicle Control History is stored. Reading the vehicle conditions recorded in both the freeze frame data and Vehicle Control History can be useful for troubleshooting.

-
If any "Engine Malfunction" Vehicle Control History item has been stored in the hybrid vehicle control ECU assembly, make sure to clear it. However, as all Vehicle Control History items are cleared simultaneously, if any Vehicle Control History items other than "Engine Malfunction" are stored, make sure to perform any troubleshooting for them before clearing Vehicle Control History.

HINT:
Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
