Starting System - 2.5L: Other Ford Kuga II

Module Network Input Messages Powertrain Control Module (PCM)

This vehicle is equipped with a PATS that disables the engine from starting if an unprogrammed PATS key is used or an invalid PCM ID is received. The PATS is controlled by the BCM . If there is a PATS concern that disables the engine, the IPC displays the corresponding message in the message center.

Refer to: PASSIVE ANTI-THEFT SYSTEM (PATS) - SYSTEM OPERATION AND COMPONENT DESCRIPTION .

The starting system controls the cranking of the engine. Under normal operation, 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 enable message from the BCM
3. Correct transmission 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. When the starter relay coil is energized, it provides voltage to the starter solenoid, allowing the starter motor to crank the engine.

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.

Powertrain Control Module (PCM)

The PCM provides power and ground to the starter relay to initiate cranking of the engine.

The starting system controls the cranking of the engine. The starter motor is enabled by the starter relay when the relay is activated by the PCM . The PCM receives inputs from the ignition switch, TCM and the BCM before activating the starter relay to initiate cranking of the engine.

Activation

1. Refer to: «STARTER MOTOR»(ref-658914-S20216875562014092900000) .
2. Check the wear patterns on the starter drive gear and the flywheel or flexplate ring gear. If the wear pattern is normal, install the starter motor. Refer to: «STARTER MOTOR»(ref-658914-S20216875562014092900000) .
3. If the starter drive gear and the flywheel or flexplate ring gear are not fully meshing and the gears are scored or damaged, install a new starter motor. Refer to: «STARTER MOTOR»(ref-658914-S20216875562014092900000) .
4. If necessary, install a new flywheel or flexplate. Refer to: «FLEXPLATE»(ref-658857-S31613231262014092900000) .
