PUSH-BUTTON START Engine does not Start

DESCRIPTION

When the key is in the vehicle and the engine switch is pressed, the certification ECU (smart key ECU assembly) receives a signal and changes the power source mode. In addition, when the shift lever is in P or N and the brake pedal is depressed, the engine can be started by pressing the engine switch.

Tech Tips


  • When the certification ECU (smart key ECU assembly) is replaced with a new one and the cable is connected to the negative (-) battery terminal, the power source mode changes to on (IG).

  • When the battery cable is disconnected and reconnected, the power source returns to the mode it was in before the battery cable was disconnected.

INSPECTION PROCEDURE

Note


  • When using the GTS with the engine switch off, connect the GTS to the DLC3 and turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the GTS and the vehicle begins. Then select Model Code "KEY REGIST" under manual mode and enter the following menus: Body Electrical /Entry&Start(CAN). While using the GTS, periodically turn a courtesy light switch on and off at intervals of 1.5 seconds or less to maintain communication between the GTS and the vehicle.

  • The push-button start uses a multiplex communication system (LIN communication system and the CAN communication system). Inspect the communication function by following How to Proceed with Troubleshooting Click here. Troubleshoot the push-button start after confirming that the communication systems are functioning properly.

  • If the push-button start is disabled through the customize function, enable the system before performing troubleshooting Click here.

  • Before replacing the certification ECU (smart key ECU assembly), steering lock ECU (steering lock actuator assembly), ECM or ID code box (immobiliser code ECU), refer to the push-button start precaution Click here.

  • Inspect the fuses of circuits related to this system before performing the following inspection procedure.

  • If the steering lock ECU (steering lock actuator assembly) is replaced, be sure to confirm that the steering is unlocked by turning the steering wheel to the left and right before starting the engine. If the steering is locked for any reason, open and close a door with the engine switch off, and then unlock the steering by pressing the engine switch. This prevents the engine from starting while the steering is locked.

  • After completing repairs, confirm that the problem does not occur.

Tech Tips

If the brake pedal is repeatedly depressed while the engine is stopped, the brake booster pressure is released and the force required to depress the brake pedal to illuminate the stop lights increases.

PROCEDURE


  1. CHECK BATTERY


    1. Measure the battery voltage.

      Standard voltage
      11 to 14 V

      Tech Tips


      • It may be possible to tell whether the vehicle battery is discharged by operating the horn.

      • If the battery voltage is less than 11 V, charge or replace it.


    OK

  2. CHECK FOR DTC


    1. Using the GTS, confirm the output of DTCs for all systems.

      OK

      Note

      Make sure that no DTCs are output. If any DTCs are output, proceed to the Diagnostic Trouble Code Chart.


    NG

    GO TO DTC CHART

    OK

  3. CHECK WAVE ENVIRONMENT


    1. If the problem occurs in certain locations or times of day, the possibility of wave interference is high.

      Tech Tips

      Whether or not the problem is due to wave interference can be checked by holding the electrical key transmitter sub-assembly near the door control receiver (RF band).
