8 APPENDIX B (Refer to online documents for latest information) ESM Extract example for Manual Transmission: FUNCTION DESCRIPTION When the stop/start system readiness conditions are satisfied while the vehicle is moving, the system is ready. When the stop/start system operation conditions are satisfied while the vehicle is in a stop condition, the engine is stopped. During stop/start system operation, stopping time, the amount of fuel saved by the stop/start system and CO2 saved information are indicated on the combination meter. When the engine restart conditions are satisfied, ECM activates the engine restart relay, the engine restart bypass control relay, and the engine restart bypass relay to restart the engine. And the DC/DC converter boosts the voltage during cranking to protect the electrical equipment from low voltage. After restarting the engine, the stop/start indicator lamp and the indication on the information display turn OFF. Stop/Start Readiness Condition ECM judges stop/start system is ready when the following conditions are satisfied.
