Start motor assembly
1. SYSTEM DESCRIPTION
The starter (start motor) starts the engine with rotational power by converting the electric energy to the
mechanical energy.
When the engine is cranking, the pinion gear meshes with the ring gear. If the ring gear overruns, the
pinion gear clutch overruns to protect the pinion gear.

(1) Engine start
SKM performs the authentication process for the SMART key and sends the engine start request to
EMS if there is a normally coded SMART key when pressing the Engine Start/Stop button with the

SKM sends the start request signal to PCAN network and the cranking request to BCAN network by
“SMART key location” signal when receiving the engine start signal by Engine Start/Stop
button.
SKM turns off the IGN2/ACC relay during cranking to shut down the electric loads.
SKM receives the starting status signal from EMS throug PCAN.

EMS starts to crank the engine after checking the pre-heating condition if it receives the engine
cranking request 1 when pressing the Engine Start/Stop button. EMS starts to crank the engine
immediately if it receives the engine cranking request 2 when pressing the Engine Start/Stop button. 1.
