Technical Description (Comment)
WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
The ETACS-ECU operates the door ajar tone alarm function, based on input signals from the following switches and the front-ECU:
- Ignition switch (IG1)
- Driver's and passenger's door switches
- Trunk lid latch switch
- Speed sensor
If the function does not work normally, a defect on the relevant circuit or the ETACS-ECU may be suspected.
