Remote Starting System: Operation
All of the following conditions must be met before the engine will remote start:
Remote Start Operation:
- The Radio Frequency Hub (RFH) detects that the remote start button has been pressed twice,
- The RFH then broadcasts a message over the security K-line to the Keyless Ignition Node (KIN).
- The Body Control Module receives the "Starter Enable" request over the CAN-C bus.
- Once the following conditions have been met, the BCM broadcasts the request over the CAN-C bus:
- Shift lever in PARK
- Doors closed
- Hood closed
- HAZARD switch off
- BRAKE switch inactive (brake pedal not pressed)
- Battery at an acceptable charge level
- FOB PANIC button not pressed
- System not disabled from previous remote start event
- Vehicle theft alarm not active
- Ignition in OFF state
- Suitable fuel level condition
- The Powertrain Control Module (PCM) receives the "Starter Enable" request over the CAN-C bus.
- The PCM applies a Low Side Driver (LSD) as needed to energize the starter relay.
- Starter Relay K1 is actuated. This relay is powered by a dedicated 10A fuse in the Power Distribution Center (PDC) allowing the starter to crank.
The optional Smart Remote Start system - which operates from as far as 200 feet - not only starts the vehicle via fob activation, but also activates the climate control and (if equipped) the optional heated/ventilated seats and optional heated steering wheel depending on temperatures outside and inside the car.
The remote start antenna is used to provide a greater range for remote start operation and is connected to, and monitored by the RFH. The RFH will perform self- diagnostics on the attached remote start antenna to determine if it is connected to the RFH and drawing current.
