- ENGINE START SYSTEM OPERATION
- When the engine switch is pressed with the brake pedal depressed and the shift lever in P or N, the main body ECU determines that it is an engine start request.
- The certification ECU and other ECUs perform key verification via the LIN communication line.
- The main body ECU activates the ACC relay.
- The main body ECU activates the IG1 and IG2 relays. The engine switch indicator light illuminates in green.
- The certification ECU outputs a steering unlock signal. The signal is sent to the steering lock ECU via the main body ECU.
- The main body ECU sends an engine start request signal to the ECM.
- The ECM sends an ACC cut request signal to the main body ECU.
- The ECM and main body ECU activate the ST cut relay.
- The main body ECU deactivates the ACC relay until the ECU detects an engine start.
- The ECU reactivates the ACC relay and turns off the engine switch indicator light.SYMBOL OF MAIN BODY ECU SIGNAL REFERENCE
