1. Check the DTCs (Present trouble code).
  1. Turn the engine switch on (IG), and wait for approximately 60 seconds.
  2. Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3.
    - SST: 09843-18040
    NOTE: Connect the terminals to the correct positions to avoid a malfunction.
2. Check the DTCs (Past trouble code).
  1. Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3.
    - SST: 09843-18040
    NOTE: Connect the terminals to the correct positions to avoid a malfunction.
  2. Turn the engine switch on (IG), and wait for approximately 60 seconds.
3. Read the DTCs.

  1. Read the blinking patterns of the DTCs. As examples, the blinking patterns for the normal system code and trouble codes 11 and 31 are shown.
    - Normal system code indication (without past trouble code)
      The light blinks twice per second.
    - Normal system code indication (with past trouble code)
      When the past trouble code is stored in the center airbag sensor, the light blinks only once per second.
    - Trouble code indication
      The first blinks indicates the first DTC. The second blinks occurs after a 1.5-second pause.
    If there is more than 1 code, there will be a 2.5-second pause between each code. After all codes are shown, there will be a 4.0-second pause, and then all codes will be repeated.
    
    HINT:
    - If 2 or more malfunctions are found, the indication begins with the smaller-numbered code.
    - If DTCs are indicated without connecting the terminals, proceed to Diagnosis Circuit .
CLEAR DTC (Using SST Check Wire)
1. When the engine switch is turned off, the DTCs are cleared.
  HINT:
  
  Depending on the DTC, the code may not be cleared by turning off the engine switch. In this case, proceed to the next procedure.
2. Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3, and then turn the engine switch on (IG).
  - SST: 09843-18040
3. Disconnect terminal TC of the DLC3 within 3 to 10 seconds after the DTCs are output, and check if the SRS warning light comes on after 3 seconds.
4. Within 2 to 4 seconds after the SRS warning light comes on, connect terminals 13 (TC) and 4 (CG) of the DLC3.
5. The SRS warning light should go off within 2 to 4 seconds after connecting terminals 13 (TC) and 4 (CG) of the DLC3. Then, disconnect terminal 13 (TC) within 2 to 4 seconds after the SRS warning light goes off.
6. The SRS warning light comes on again within 2 to 4 seconds after disconnecting terminal 13 (TC). Then, reconnect terminals 13 (TC) and 4 (CG) within 2 to 4 seconds after the SRS warning light comes on.
7. Check if the SRS warning light goes off within 2 to 4 seconds after connecting terminals 13 (TC) and 4 (CG) of the DLC3. Also check if the normal system code is output within 1 second after the SRS warning light goes off.
  If DTCs are not cleared, repeat this procedure until the codes are cleared.

CHECK DTC (Using Techstream)
1. Connect the Techstream to the DLC3.
2. Turn the engine switch on (IG).
3. Turn the Techstream on.
4. Enter the following menus:
  Select: Body Electrical/SRS Airbag/Trouble Codes.
CLEAR DTC (Using Techstream)
1. Connect the intelligent Techstream or Techstream to the DLC3.
2. Turn the engine switch on (IG).
3. Turn the Techstream on.
4. Enter the following menus:
  Select: Body Electrical/SRS Airbag/Trouble Codes.
5. Erase the DTCs.
