Starting System - without Intelligent Access (IA)

Component Description

Integrated Keyhead Transmitter (IKT)

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

Passive Anti-Theft Transceiver

REFER to Passive Anti-Theft System (PATS) Transceiver .

Body Control Module (BCM)

The BCM (Body Control Module) is the gateway module, translating messages on the HS-CAN (High Speed Controller Area Network) to MS-CAN (Medium Speed Controller Area Network). 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 (Body Control Module) and PCM (Powertrain Control Module) during engine cranking.

Powertrain Control Module (PCM)

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

Tire Pressure Monitor (TPM) Module

The TPM (Tire Pressure Monitor) module is a receiving antenna that receives high frequency signals. When a remote start request is initiated from the IKT (Integrated Keyhead Transmitter) the TPM (Tire Pressure Monitor) module receives the signal and communicates that remote start request message via the MS-CAN (Medium Speed Controller Area Network) to the BCM (Body Control Module) to initiate a remote start event.

Transmission Range (TR) Sensor

The TR (Transmission Range) sensor is located inside of the transaxle and indicates gearshift position to the PCM (Powertrain Control Module). The PCM (Powertrain Control Module) uses that information to enable the starting system to start the engine in PARK or NEUTRAL. REFER to Sensors and Switches .
