Starting System

WARNING: This page is about a different car, the 2016 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: This vehicle is equipped with Passive Anti-Theft System (PATS) that disables the engine from cranking and starting if an unprogrammed Passive Anti-Theft System (PATS) key is used or an invalid Powertrain Control Module (PCM) ID is received. Passive Anti-Theft System (PATS) is controlled by the Body Control Module (BCM). If there is a Passive Anti-Theft System (PATS) concern that cause the engine to be disabled, the Instrument Panel Cluster (IPC) displays "STARTING SYSTEM FAULT" in the message center. Anti-Theft - Passive Anti-Theft System (PATS), Without Intelligent Access (IA) .

Under normal operation, when the ignition is turned to START, the PCM receives the following inputs:

Ignition switch request to start the engine
Run/start relay voltage
Passive Anti-Theft System (PATS) is enable message
Correct transmission PARK or Neutral input from the Transmission Range (TR) sensor

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. Once the starter motor begins to crank, the ignition switch may be released to the RUN position.

The PCM disengages the starter once an engine Revolutions Per Minute (RPM) threshold is reached, a set crank time is exceeded or the ignition is turned OFF.

If cumulative crank time exceeds 60 seconds within 60 minutes, the starter will be inhibited for 15 minutes and the PCM sets a DTC. Refer to the Owner's Literature for more information.

Remote Start

If equipped, the remote start feature allows the operator to remotely start the engine from up to 20 meters (65.62 feet) away and is activated by pressing the lock button on the IKT, 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. The BCM acknowledges the start request by flashing the exterior lights twice. When the IKT transmits a remote start request signal to the PATS transceiver module. The PATS transceiver module 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.

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. During the remote start cycle the power windows are inhibited and the radio will not turn on automatically but may be switched 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.
