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

DTC Code DTC Name
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. In addition, when the shift lever is in N*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 N*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.

  • The entry and start system (for Start Function) uses the LIN communication system and CAN communication system. Inspect the communication function by following How to Proceed with Troubleshooting. Troubleshoot the entry and start system (for Start Function) after confirming that the communication systems are functioning properly.

    Click here

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

    Click here

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

  • Before replacing the certification ECU (smart key ECU assembly) or electrical key transmitter sub-assembly, refer to entry and start system (for Start Function) Precaution.

    Click here

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

Tip:

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

  • If the engine switch is turned from on (IG) to on (ACC) with the shift lever in any position other than N, then the shift lever is moved to N and the engine switch is pressed with the brake pedal depressed, the engine switch will be turned off.*

  • 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.*
