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 Module (RFHM) detects that the remote start button has been pressed twice,
• The RFHM 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 RFHM. The RFHM will perform self- diagnostics on the attached remote start antenna to determine if it is connected to the RFHM and drawing current.
