Component Description

Integrated Keyhead Transmitter (IKT) 

The RKE system uses an IKT. The IKT incorporates both the PATS and RKE functions into a single device. The factory installed remote start (if equipped), is controlled by the IKT function and allows the engine to be started from outside the vehicle. The RKE functions controls the door lock/unlock features.

Passive Anti-Theft Transceiver 

REFER to Passive Anti-Theft System (PATS) - Without Intelligent Access (IA)

Body Control Module (BCM) 

The BCM is the gateway module, translating messages on the HS-CAN to MS-CAN. This allows a message to be distributed throughout both networks.

Ignition Switch 

The ignition switch is controlled by the ignition lock cylinder with a key. When the ignition lock cylinder is turned using the key, a mechanical connection positions the ignition switch to the selected position and allows the ignition switch to send voltage to specific components. The ignition switch sends voltage to the BCM and PCM during engine cranking.

Powertrain Control Module (PCM) 

The PCM receives input signals from sensors and other components (switches, relays). Based on this information, the PCM generates output signals to control various relays, solenoids and actuators.

Tire Pressure Monitor (TPM) Module 

The TPM module is a receiving antenna that receives high frequency signals. When a remote start request is initiated from the IKT the TPM module receives the signal and communicates that remote start request message via the MS-CAN to the BCM to initiate a remote start event.

Transmission Range (TR) Sensor 

The TR sensor is located inside of the transmission and indicates gearshift position to the PCM. The PCM uses that information to enable the starting system to start the engine in PARK or NEUTRAL. For vehicles with 6F35, REFER to Automatic Transmission - 6F35 . For vehicles with 6F50 or 6F55, REFER to Automatic Transmission - 6F50/6F55 .
