Starting System

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.
