Standard Starting System

WARNING: This page is about a different car, the 2012 Dodge Charger. However, it is still accessible from the selected car via links, so may be relevant.

When you press the Keyless Go button (KIN Button), a request is sent to RF-Hub via the private LIN. Once the RF-Hub receives the request from the KIN it then looks for the valid key via the Passive Entry Module (PEM) antennas. If the RF-Hub detects a valid key, then the RF-Hub sets the ignition position to START/CRANK. The BCM then turns the Ignition status to START/CRANK.

Then the BCM sends a command to turn the vehicle to the "RUN/CRANK" If conditions are correct to start, the PCM turn on the high side of the relay and holds the high side until the PCM turns off the signal allowing the engine to crank.

If the BCM is still in crank and the crank hold signal is true then the BCM turns on the Low side of the relay and the engine will start cranking.

Once the engine has started the PCM deactivates the double start over ride. The BCM will then deactivate the starter either when the engine starts or the maximum time has been reach for the tip start (10 sec for Gas and 25 sec for diesel).

At the same time the engine starts the RF-Hub will put the ignition from "Crank" to "RUN" if the start type is "TIP Start" or the 2 second time expires or the engine controller indicates the vehicle is not in park or neutral

The engine can be manually shut down by the driver with speeds over 5 MPH in any gear.
