Starting System
WARNING: This page is about a different car, the 2016 Ford Special Service Police Sedan and 2016 Ford Police Interceptor Sedan. However, it is still accessible from the selected car via links, so may be relevant.
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 causes the engine to be disabled, the IPC displays "STARTING SYSTEM FAULT" in the message center. 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:
- Ignition switch request to crank the engine
- Run/start relay voltage
- PATS is enabled message
- Correct transaxle PARK or NEUTRAL input from the 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.
The PCM disengages the starter once an engine 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 is disabled for 15 minutes and the PCM sets a DTC. Refer to the Owner's Literature for more information.
