SAE Code: P05B2 | 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
- Hall IC Signal Malfunction
If the grille shutter ECU (swing grille actuator
assembly) detects a stuck high or stuck low signal from either hall IC1
or hall IC2, it will output a malfunction signal to the ECM and the ECM
will store a DTC.

- Hall IC Signal Reception Malfunction
If the grille shutter ECU (swing grille actuator
assembly) detects a stuck high or stuck low signal from both hall IC1
and hall IC2, 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
