Either of the following conditions is met and the ECM receives a malfunction signal 17 times* (1 trip detection logic):
- Open detected in the grille shutter motor (swing grille actuator assembly) when a grille shutter operation is requested.

SAE Code: P05A2 | 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
- Grille Shutter Motor (Swing Grille Actuator Assembly) Malfunction
If the grille shutter ECU (swing grille actuator
assembly) detects a malfunction in the grille shutter motor drive
circuit when a grille shutter operation is requested, it will output a
malfunction signal to the ECM and the ECM will store a DTC.

CAUTION / NOTICE / HINT
NOTICE:
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. PROCEDURE
