Starting System: Other Ford Escape III

Remote Start

The remote start feature allows the operator to remotely start the engine from up to 100 meters (328 feet) away and is activated using the IKT. Once started, the engine runs for 10 minutes. The run time can be extended by the operator.

Network Message Chart

NETWORK INPUT MESSAGES PCM

Note. This vehicle is equipped with PATS that disables the engine from cranking and starting if an unprogrammed PATS key is used or an invalid PCM ID is received. PATS is controlled by the BCM. If there is a PATS concern that disables the engine, the IPC message center displays "STARTING SYSTEM FAULT". For additional information, refer to PATS, ANTI-THEFT - PASSIVE ANTI-THEFT SYSTEM (PATS), WITHOUT INTELLIGENT ACCESS (IA) .

When the ignition is turned to START, the PCM receives the following inputs

1. Voltage signal on the crank detect circuit from the ignition switch
2. PATS is enabled message from the BCM
3. Correct transaxle PARK or NEUTRAL input from the automatic transmission

When the PCM receives the correct inputs, voltage and ground is supplied to the starter relay coil. The starter relay coil is energized causing the relay contacts to close providing voltage to the starter solenoid, allowing the starter motor to crank and start the engine. The PCM disengages the starter once an engine RPM threshold is reached, a set crank time is exceeded or the ignition is turned OFF.

The factory remote start system (if equipped) does not operate if the ignition is in the RUN/START position or the hood is not closed.

The remote start system can be enabled or disabled by the customer. When enabled, the customer can set the engine run time for 5, 10 or 15 minutes. For information on setting the engine run time, refer to the Owner's Literature or INSTRUMENTATION, MESSAGE CENTER, AND WARNING CHIMES .

When equipped with remote start, a remote start event is initiated when the IKT transmits a remote start request signal to the PATS transceiver, which sends a remote start request message to the BCM. The BCM sends a crank request message to the PCM. The factory equipped remote start system does not operate if the ignition is in the RUN/START position or the hood is not closed.

The remote start system allows the operator to start the engine from up to 100 meters (328 feet) away, by pressing a sequence of buttons on the IKT. The remote start system is activated by pressing the lock button on the IKT once to make sure the doors are locked, followed by 2 presses of the remote start button. The 3 button presses must occur within 3 seconds of each other. The BCM acknowledges the remote start request by flashing the exterior lights twice. Once started, the engine runs for 10 minutes (default run time is 10 minutes; the time can be programmed by the customer to 5, 10 or 15 minutes) and the parking lights remain illuminated until the cycle is complete. The remote start duration can also be extended by initiating remote start while the first timer is still running or by initiating a completely independent start cycle when the first has completed. No more than 2 remote start sequences can occur within a one hour period, unless the ignition is set to the RUN/START position between the remote start requests. During the remote start cycle the power windows are inhibited and the radio will not turn on automatically but may be turned on manually from inside the vehicle. If the remote start system fails to start the horn chirps twice.

To transition from remote start mode to drive mode, use a programmed IKT to switch the ignition to the RUN position. If a programmed IKT is not used, the engine shuts off.

To deactivate the remote start system, press the remote start button once. When deactivating the remote start system the parking lights turn off to give a visual indication that the engine and climate control features have turned off. It may be necessary to be closer to the vehicle to deactivate the remote start feature than it was to initiate it due to ground deflections and added noise from the engine running.

The remote start system conditions the cabin temperature during remote start based on the outside temperature. For information on cabin temperature conditioning during remote start, refer to CLIMATE CONTROL SYSTEM - ELECTRONIC MANUAL TEMPERATURE CONTROL (EMTC) or CLIMATE CONTROL SYSTEM - DUAL AUTOMATIC TEMPERATURE CONTROL (DATC) .

BCM

The BCM is the gateway module, translating HS-CAN messages to the 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 PCM during engine cranking.

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 control the door lock/unlock features.

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, including the starter relay.

PATS Transceiver

The PATS transceiver is a receiving antenna that receives high frequency signals. When a remote start request is initiated from the IKT the PATS transceiver receives the signal and communicates that remote start request message to the BCM. For additional information, refer to ANTI-THEFT - PASSIVE ANTI-THEFT SYSTEM (PATS), WITHOUT INTELLIGENT ACCESS (IA) .

TR Sensor

The TR sensor is located inside the transaxle 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 additional information, refer to AUTOMATIC TRANSAXLE/TRANSMISSION - 6F35 .

The remote start feature allows the operator to remotely start the engine from up to 100 meters (328 feet) away and is activated using the IKT. Once started, the engine runs for 10 minutes. The run time can be extended by the operator.

The RFA module in conjunction with the BCM controls the ignition modes and in conjunction with the PCM controls the starting system.

During a start event, when the start/stop switch is pressed in combination with the brake pedal, the RFA module, PCM and BCM receive a request to start the engine.

The PCM recognizes the correct inputs from the BCM and TR sensor and provides voltage and ground to energize the starter relay coil and close the starter relay contacts. The starter relay contacts close, providing voltage to the starter solenoid, allowing the starter motor to crank the engine. The PCM disengages the starter motor once an engine RPM threshold is reached, a set crank time is exceeded or the start/stop button is pressed indicating an engine shutdown.

The factory remote start system (if equipped) does not operate if the ignition is in the RUN/START position or the hood is not closed.

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

IA key

The IA key incorporates both the PATS and the RKE transmitter functions in a single device. The IA key must be located inside the vehicle for engine starting. When the IA key is activated it sends out a frequency signal that is received by the RFR module. The IA key also contains a key blade that is used to enter the vehicle as a backup.

Start-Stop Switch

The start/stop switch is a momentary contact switch that is hardwired to the RFA module, BCM, and PCM. When the switch is pressed, it signals the RFA module, BCM and PCM there is a request to either switch the ignition on or start the engine. The start/stop switch is connected to both modules as a backup in case of a failure. If there is a circuit failure to either module from the start/stop switch, the modules communicate the start/stop switch request to each other over the MS-CAN.

RFA Module

The RFA module interprets radio frequency signals from the RFR module and IA key transmitters. The RFA module receives input signals from various modules and other components. Based on this information, the RFA module generates an output signal to control various components such as the door locks and the liftgate.

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 including the starter relay.

RFR

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

The TR sensor is located inside the transaxle 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 additional information, refer to AUTOMATIC TRANSAXLE/TRANSMISSION - 6F35 .
