Starter Control System Diagram: M/T

The starter control system controls the starter motor.

• When the engine start/stop button pressed to select the START mode, the ECM applies current to starter cut relay 1, and starter cut relay 2, and the +B cut relay is turned on. Then battery voltage is applied to the starter solenoid, and starter motor runs.
• Once the engine start/stop button is released, the ECM keeps the starter motor running until the engine starts. If the ECM detects that the engine starts, the ECM stops applying current to the relays, and the starter motor stops.
• If you press the engine start/stop button to select START mode while the engine is running, the starter motor does not operate.
• In the following cases, the ECM stops the starter motor:
  • After the starter motor operates for 10 seconds (to prevent the starter motor from overheating).
  • If the engine RPM is too high during starter motor operation.
• If there is a problem with the starter control system, a message appears on the gauge display. When the message is on, the engine can only be started by pressing and holding the engine start/stop button until the engine starts.
