ENTRY AND START SYSTEM(for Start Function) Engine does not Start

DESCRIPTION

When the electrical key transmitter sub-assembly is in the cabin and the engine switch is pressed, the certification ECU (smart key ECU assembly) receives a signal and changes the power source mode. Additionally, when the shift lever in P*1 and the brake pedal*1 or clutch pedal*2 is depressed, the engine can be started by pressing the engine switch. If the steering is unlocked, the engine can also be started by pressing the engine switch with the shift lever in P*1 and the brake pedal*1 or clutch pedal*2 depressed.

CAUTION / NOTICE / HINT

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.

  • If the entry and start system (for Start Function) has been canceled, enable the system before performing troubleshooting.

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

  • Before replacing the certification ECU (smart key ECU assembly) or an electrical key transmitter sub-assembly, refer to the Service Bulletin.

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

  • After repair, confirm that no DTCs are output by performing "DTC Output Confirmation Operation".

  • When disconnecting the cable from the negative (-) battery terminal while performing repairs, some systems need to be initialized after the cable is reconnected.

  26. READ VALUE USING GTS (Neutral SW/ Clutch SW)


    1. Disconnect the C34*1, C154*2, C92*3 and G184*4 ECM connector.


      • *1: for 1GR-FE

      • *2: for 2TR-FE

      • *3: for 1KD-FTV

      • *4: for 1GD-FTV

    2. Read the Data List according to the display on the GTS.

      Power Source Control
      Tester Display Measurement Item Range Normal Condition Diagnostic Note
      Neutral SW/ Clutch SW Shift position (P and N) ON or OFF

      ON: Shift lever in P or N

      OFF: Shift lever in any position other than P or N

      • Use this item to determine whether the park/neutral start switch assembly is malfunctioning.

      • When the engine cannot be started due to a park/neutral start switch assembly malfunction, OFF is displayed.
      OK
      The GTS display changes correctly in response to the shift state.
