Tech Tips

*: 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

CAUTION / NOTICE / HINT

Note

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.

Tech Tips

Read freeze frame data using the GTS. 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.
