System Description [07/2020 - ]

The electronic shift lever system electrically controls the transmission parking lock mechanism and shift control mechanism.

The shift control ECU judges the vehicle condition based on the information from each sensor, switch and ECU and performs appropriate shift control based on the driver's operation of the shift lever or P position switch.

If a malfunction occurs in the electronic shift lever system, the master warning light illuminates in the combination meter assembly (according to the malfunction mode, the shift position indicator (P, R, N, D, M) turns off (not in all cases)), the MIL turns on (not in all cases) and a warning message is also displayed on the multi-information display.

When the shift control ECU detects a malfunction, the DTC is stored in the ECM.

1. Shift position indicator (P, R, N, D, M) ON (indicator illuminated (normal)) or OFF (indicator off (not normal)) is displayed.

1. A reject function is equipped to reject incorrect shift switching when the shift lever is operated incorrectly.
2. When the reject function operates, the current shift state is maintained or switches to the neutral (N). The buzzer in the combination meter assembly sounds (2 times consecutively or once) and the master warning light blinks. Also, the recommended handling method is displayed on the multi-information display.
   REJECT FUNCTION OPERATION CHART
   
   

   Shift operation performed by reject function	Shift state after reject function operation	Message displayed on multi-information display
   Changes the shift state when battery voltage was low	Maintains current shift state	Battery low Shifting unavailable See owner's Service Information
   Changes the shift state to and from park (P) within a short period of time	Park (P)	Shifting unavailable Wait a moment and Shift again
   Changes the shift state from park (P) or neutral (N) to manual (M)	Maintains current shift state	Vehicle must be in D to shift into M
   Changes the shift state to drive (D), reverse (R) or manual (M) when the engine switch is on (IG) and the engine is stopped Changes the shift state from park (P) when the engine is cranking Changes the shift state from park (P) when the required voltage to change the shift state is not available	Park (P)	Engine must be started to shift
   Changes the shift state from park (P) with brake pedal not depressed When the vehicle is stopped, the driver attempted to change the shift position without depressing the brake pedal, after the shift control ECU was replaced or the battery was cleared	Park (P) Maintains current shift state	Depress brake to shift
   Changes the shift state directly to manual (M) from reverse (R)	Neutral (N)	Shifted into N Vehicle must be in D to shift into M
   Changes the shift state to drive (D) while backing up	Neutral (N)	Shifted into N Vehicle must be stopped to shift into D
   Changes the shift state to reverse (R) while driving forward	Neutral (N)	Shifted into N Vehicle must be stopped to shift into R
   P position switch briefly pressed while driving	Maintains current shift state	-
   P position switch pressed repeatedly or continually pressed while driving	Neutral (N)	Shifted into N Vehicle must be stopped to shift into P
   Changes the shift state form park (P) when accelerator and brake pedals depressed simultaneously	Park (P)	Release accelerator to shift
   Changes the shift state to neutral (N) when the system detects the shift lever was moved to N but not enough time elapsed for manual switching	Maintains current shift state*	Temporarily hold shift lever in N position to shift into N

   *: The shift state may shift to neutral (N) depending on the driving conditions.

1. The engine switch can be turned off while holding the shift state neutral (N) by performing the following operation.
   1. Change the shift state neutral (N).
   2. Return the shift state to the neutral position.
   3. Move the shift state neutral (N) again (the buzzer sounds).
   4. Turn the engine switch off with the shift state held in the neutral (N) or within 5 seconds after releasing the shift lever (the buzzer will sound and a confirmation message will be displayed on the multi-information display).
   5. The engine switch will be turned on (ACC) with the shift state neutral (N).

      HINT: 

      • Pressing the P switch will switch the shift state to park (P) and exit from N range hold mode.
      • Do not turn the engine switch on (IG) or off unnecessarily while in N range hold mode except in an emergency.

If it is detected that the driver has exited the vehicle* while the shift state not park (P), the shift state will be changed to park (P) automatically.

*: The driver seat belt buckle is off, the driver seat door is open, and the brake pedal is released.

HINT: 

This function (auto-shifting function) operates if the driver exits the vehicle while the shift state not park (P). It does not function at all times.
