INSPECTION PROCEDURE

NOTICE:

1. 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 the vehicle type under manual mode and enter the following menus:
   Body Electrical / Entry&Start. 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.
   
2. The entry and start system (for Start Function) 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 entry and start system (for Start Function) after confirming that the communication systems are functioning properly.
   
3. If the entry and start system is disabled through the customize function, enable the system before performing troubleshooting (Click here).
   
4. 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 entry and start system (for Start Function) precaution (Click here).
   
5. Inspect the fuses of circuits related to this system before performing the following inspection procedure.
   
6. 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.
   
7. After completing repairs, confirm that the problem does not occur.
   

HINT:

If the brake pedal*1 or clutch pedal*2 is repeatedly depressed while the engine is stopped, the brake booster pressure is released and the force required to depress the brake pedal*1 or clutch pedal*2 to illuminate the stop lights increases.
