HYBRID CONTROL SYSTEM Drive Mode Select Switch Circuit

DESCRIPTION

When the drive mode select switch (pattern select switch assembly) is operated, a switch signal is sent to the hybrid vehicle control ECU and the hybrid vehicle control ECU changes the drive mode.

Tech Tips


  • If the power switch is turned off while in POWER mode, the drive mode will automatically be changed to NORMAL mode when the power switch is turned on (IG).

  • If the power switch is turned off while in NORMAL mode or ECO mode, the selected drive mode will resume when the power switch is turned on (IG).
