Circuit description

With the electrical key transmitter SUB-ASSY in the vehicle interior, press the engine switch. The collation ECM (smart key ECM ASSY) receives the signal and the power mode changes. With the shift lever in P *1 or N *1, if you depress the brake pedal *1 or the clutch pedal *2 and press the engine switch, you can start the engine.

*1: With automatic transmission

NOTE:
  • Only if the steering lock is unlocked, even if the shift lever is in the N position, you can start the engine. *
  • In IG ON, if the shift lever is in a position other than P, if you press the engine switch, the power changes to ACC ON. After that, if you move the shift lever to P and press the engine switch while depressing the brake pedal, the power changes to IG OFF. *
  • If you remove and then reconnect the battery cable, the power returns to the mode it was before you removed the cable.
