Wake-Up Diagnosis: Notes
WARNING: This page is about a different car, the 2012 Subaru Forester. However, it is still accessible from the selected car via links, so may be relevant.
Store the number of wake-up activation when the ECM wakes up by the soaking timer IC. Next time when the ignition switch is ON, if the number of wake-up activation does not reach the predetermined value even though the counter in soaking timer IC exceeds the activation setting time, judge as wakeup malfunction.
