Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Repair Instruction: Initialization
- FOR VEHICLES EQUIPPED WITH SMART ACCESS SYSTEM
- Immediately after the battery terminal is reconnected, the main body ECU will not function, and therefore, the smart access system will not operate. To activate the main body ECU, perform a wireless door unlock or lock operation.
- If the battery has been discharged, the engine cannot be started even after the battery has been recharged because the steering lock position cannot be recognized correctly. To allow the steering lock ECU to learn the steering lock position, initialize the steering lock ECU.
- To start the engine after the battery terminal is reconnected, perform the following:
- Open and close the driver's door.
- Wait for 10 seconds or more.
HINT:
The first attempt to start the engine will fail because the steering lock ECU has not learned the steering lock position yet. This does not indicate a malfunction. The engine can be started normally on the second or subsequent attempt.
