The intermediate starter switch, which is installed on cars with a manual transmission, prevents the car from moving away when the engine is started, thus increasing safety - the engine cannot be started until the clutch pedal is depressed.
Service Data
Note: The location of the starting system components is shown using a gasoline engine as an example. The arrangement of components for a diesel engine is completely similar.
The starter relay, located in the relay and fuse box, supplies power to the starter when it receives a signal from the ECM. When current flows between A-B in the circuit shown in the figure, an electromagnetic field is generated, due to which the switch between CD closes. The current flowing through the switch between the CDs is supplied to the starter.
The starter, mounted on the rear of the engine on the left side, rotates the crankshaft through the flywheel ring gear, causing the engine to start. The starter is equipped with a coaxial gearbox, thanks to which it is possible to obtain high torque.
