  2. PRECAUTIONS WHEN CHECKING FOR DTCS


    1. When the cable is disconnected from the negative (-) battery terminal, the DTCs stored in the steering lock ECU are cleared. Be sure to record any output DTCs immediately.

    2. Normally, with the engine switch off, even if the intelligent tester is connected to the vehicle, the information stored in the smart entry and start system related ECUs (the certification ECU (smart key ECU assembly), main body ECU, etc.) cannot be read. However, smart entry and start system DTCs and Data List information can be confirmed even if the engine switch is off using either of the two methods below:


      • Connect the intelligent tester to the vehicle, and turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the intelligent tester and vehicle begins (the intelligent tester screen changes when communication begins).

      • Connect the intelligent tester to the vehicle and select "Manual" from the initial screen on the intelligent tester. Select "Key Code Registration" under model code.

  3. PRECAUTIONS WHEN REPLACING STEERING LOCK ECU (STEERING LOCK ACTUATOR ASSEMBLY)


    1. 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 lock by pressing the engine switch. This prevents the engine from starting while the steering is locked.

  4. PRECAUTION FOR REGISTRATION


    1. If replacing any of the following parts, refer to Service Bulletin.


      1. ID code box (Immobiliser code ECU) (w/o wireless door lock buzzer answer back function)

      2. Certification ECU (Smart key ECU assembly)

      3. Steering lock ECU (Steering lock actuator assembly)

      4. ECM

      5. Electrical key transmitter sub-assembly (Key)
